Definitions
- the invention relates to a method for producing a hardened profile component with cathodic corrosion protection and to a hardened metallic P. profile component with cathodic corrosion protection.
- Low alloyed steel sheets are not corrosion resistant after being produced by suitable forming steps, either by hot rolling or cold rolling. This means that after a relatively short time and due to the humidity at the surface, oxidation occurs.
- corrosion is the reaction of a metallic material, with its environment, which causes a measurable change in the material and can lead to an impairment of the function of a metallic component or an entire system.
- steel is usually protected so that it can withstand the corrosion loads during the required service life.
- the avoidance of corrosion damage can be achieved by influencing the properties of the reactants and / or by changing the reaction conditions, separating the metallic material from the corrosive Medium done by applied protective layers and by electrochemical measures.
- a corrosion protection layer is a layer produced on a metal or in the near-surface region of a metal, which consists of one or more layers. Multi-layer coatings are also referred to as corrosion protection systems.
- Possible corrosion protection layers are, for example, organic coatings, inorganic coatings and metallic coatings.
- the purpose of metallic corrosion protection layers is to transfer the properties of the support material to the steel surface for as long as possible. Accordingly, the choice of an effective metallic corrosion protection requires the knowledge of the corrosion-chemical relationships in the system steel / coating metal / attacking medium.
- the coating metals can be electrochemically nobler or electrochemically less noble than steel.
- the respective coating metal protects the steel only through the formation of protective layers.
- barrier protection As soon as the surface of the coating metal has pores or was injured, a "local element" forms in the presence of moisture, in which the base partner is attacked by the metal to be protected.
- the more noble coating metals include tin, nickel and copper.
- Metallic protective layers are applied by various methods. Depending on the metal and process, the connection of the steel surface is chemical, physical or mechanical and ranges from alloy formation and diffusion to adhesion and mere mechanical clamping.
- the metallic coatings are said to have similar technological and mechanical properties to steel as they do to steel, and to behave similarly to steel in terms of mechanical stress or plastic deformity.
- the coatings should therefore not be damaged during forming and also affected by forming operations.
- the metal to be protected is immersed in molten metal melts. Due to the hot dipping, corresponding alloy layers are formed at the phase boundary of steel coating metal.
- An example of this is the hot dip galvanizing.
- Hot dip galvanizing the steel strip is passed through a zinc bath, the zinc bath having a temperature of around 450 ° C.
- Hot-dip galvanized products have high corrosion resistance, good weldability and formability, and their main applications are the construction, automotive and household appliance industries.
- a coating of a zinc-iron alloy is known.
- these products are after hot dip galvanizing at temperatures above the zinc melt point, usually between 480 ° C and 550 ° C subjected to a diffusion annealing.
- the zinc-iron alloy layers grow and absorb the overlying zinc layer. This process is called "galvannealing".
- the zinc-iron alloy thus produced also has a high corrosion resistance, good weldability and U formability.
- Main applications are the automotive and home appliance industry.
- other " coatings of aluminum-silicon, zinc-aluminum and aluminum-zinc can be produced by hot dipping.
- electrodeposited metal coatings i. the electrolytic, so under current passage deposition of metallic coatings of electrolytes.
- electrolytic coating is also possible with such metals, which can not be coated by melt-dip process.
- Conventional layer thicknesses in electrolytic coating are usually between 2.5 and 10 microns, they are thus generally lower than in enamel dip coatings.
- Some metals, e.g. Zinc also allow thick film coatings with electrolytic coating.
- Electrolytically galvanized sheets are mainly used in the automotive industry, because of the high surface quality, these sheets are used above all in the outer skin area. They have good formability, weldability and storability as well as good paintable and matt surfaces.
- the surface of the plate is scaled by heating, so that after forming and hardening the sheet surface must be cleaned, for example by sandblasting. Then the sheet is trimmed and possibly punched necessary holes.
- the sheets have a very high hardness in the mechanical processing and therefore the processing is complicated and in particular a high tool wear exists.
- US 6,564,604 B2 The purpose of US 6,564,604 B2 is to provide steel sheets which are subsequently subjected to a heat treatment, and to provide a method for producing parts by press-hardening these coated steel sheets. In this case, it should be ensured despite the increase in temperature that the steel sheet is not decarburized and the surface of the steel sheet is not oxidized before, during and after the hot pressing or the heat treatment.
- an alloyed intermetallic mixture should be applied to the surface before or after punching, which should provide protection against corrosion and decarburization and also can provide a lubricating function.
- this document proposes to use a customary, apparently electrolytically applied zinc layer, wherein this zinc layer is to be converted into a homogeneous Zn-Fe alloy layer with the steel substrate in a subsequent austenizing of the sheet substrate.
- This homogeneous layer structure is confirmed by microscopic images. Contrary to previous assumptions, this coating is said to have a mechanical resistance that prevents it from melting. In practice, however, such an effect does not show.
- the use of zinc or zinc alloys should provide cathodic protection of the edges when cuts are present.
- US Pat. No. 6,564,604 B2 specifies a coating consisting of 50% to 55% aluminum and 45% to 50% zinc, with possibly small amounts of silicon. Such a coating is not new in itself and known under the brand name Galvalume®. It is stated that the coating metals zinc and aluminum with iron should form a homogeneous zinc-aluminum-iron alloy coating. In the case of this coating, it is disadvantageous that adequate cathodic corrosion protection is no longer achieved here, but the predominant barrier protection which is thereby achieved is not sufficient for use in the press hardening process, since partial surface damage to the surface is unavoidable.
- the method described in this document is unable to solve the problem that, in general, zinc-based cathodic corrosion coatings are not suitable for protecting steel sheets which are to be subjected to a heat treatment after coating and may also be subjected to a further shaping or forming step.
- EP 1 013 785 A1 discloses a method for producing a sheet-metal component, wherein the sheet is to have an aluminum layer or an aluminum alloy layer on the surface.
- a sheet provided with such coatings is to be subjected to a press hardening process, giving as possible coating alloys an alloy with 9-10% silicon, 2-3.5% iron, balance aluminum with impurities and a second alloy with 2-4% iron and the rest aluminum with impurities.
- Such coating tions are known per se and correspond to the coating of a hot-dip aluminized steel sheet.
- In such a coating is disadvantageous in that only a so-called barrier protection is achieved. The moment that such a barrier layer is damaged or cracked in the Fe-Al layer, the base material, in this case the steel, is attacked and corroded. A cathodic protective effect is absent.
- a particularly suitable and therefore preferred coating material is aluminum or an aluminum alloy.
- zinc or zinc alloys would be suitable.
- Such a coated sheet can then be cold preformed and hot finished molded.
- this method has the disadvantage that an aluminum coating, even if it has been applied by electrolysis, no longer offers any protection against corrosion if the surface of the finished component is damaged, since the protective barrier has been breached.
- an electrodeposited zinc coating it is disadvantageous that during heating for hot forming, the zinc is largely oxidized and no longer available for cathodic protection. Under a protective gas atmosphere, the zinc evaporates.
- a method for the production of metal profile components for motor vehicles is known.
- starting material provided in strip form is fed to a roll forming unit and formed into a rolled section.
- at least partial areas of the rolled section are to be heated inductively to a temperature required for hardening and then quenched in a cooling unit.
- the rolled sections are cut to form the profile components.
- a particular advantage of roll forming is to be seen in the low production costs due to the high processing speed and low compared to a press tool costs.
- a special heat-treatable steel is used for the profile component.
- partial regions of the starting material can also be inductively brought to the hardening state before entry into the rolling profiling unit. heated temperature and quenched before cutting the rolled section in a cooling unit.
- the cutting must take place already in the hardened state, which is problematic due to the high hardness of the material.
- the profile components cut to length must be cleaned or descaled in the already described prior art and a piece of corrosion coat must be applied after the ignition has been ignited. Such corrosion coat coatings usually do not give very good cathodic corrosion protection.
- the object is to provide a method for producing a hardened profile component with a cathodic corrosion protection, wherein the cathodic corrosion protection is formed so that even the starting material has a protective layer which does not convert during the further processing in a negative way.
- Another object is to provide a cathodic anti-corrosion layer for curable profile components.
- Another object is to provide a hardened profile component with cathodic corrosion protection.
- the object is achieved by a method having the features of claim 45.
- Advantageous developments are characterized in the dependent claims.
- the inventive method provides, on a hardenable steel sheet, a coating of a mixture consisting essentially of zinc and an oxygen affinity element, such as magnesium, silicon, titanium, calcium and aluminum with a content of 0.1 to 15 wt .-% of the Apply Sauerstoffäffinen element and to heat the coated steel sheet at least partially with the access of oxygen to a temperature above the Austenitmaschinestemperatur the sheet metal alloy and before to reform, wherein the sheet is cooled after sufficient heating and the cooling rate is such that hardening of the sheet metal alloy takes place.
- a hardened component is obtained from a steel sheet having a good cathodic corrosion protection.
- the corrosion protection according to the invention for steel sheets, which are initially formed and in particular roll-profiled and then subjected to a heat treatment and formed and hardened, is a cathodic corrosion protection which is based essentially on zinc.
- 0.1% to 15% of one or more oxygen-containing elements such as magnesium, silicon, titanium, calcium, aluminum, boron and manganese or any mixture or alloy thereof are added to the zinc forming the coating. It has been found that such small amounts of an oxygen affinity element as magnesium, silicon, titanium, calcium, aluminum, boron and manganese cause a surprising effect in this particular application.
- At least Mg, Al, Ti, Si, Ca, B, Mn are suitable according to the invention as oxygen-affine elements. When aluminum is mentioned below, this is representative of the other elements mentioned.
- the application of the coating according to the invention on a steel sheet can be done, for example, by so-called hot-dip galvanizing, i. a hot-dip coating is performed wherein a liquid mixture of zinc and the oxygen-affine element (s) is applied. Furthermore, it is possible to electrolytically apply the coating, i. to deposit the mixture of zinc and the oxygen-affine element (s) collectively on the sheet surface or first deposit a zinc layer and then sequentially deposit on the zinc surface one or more oxygen-affine elements or any mixture or alloy thereof or by vapor deposition or other suitable method deposit.
- an approximately two-layer corrosion protection layer is formed, which consists of a cathodically highly effective layer, with a high proportion of zinc and a very thin oxidation protection layer of one or more oxides (A1 2 0 3 , MgO, CaO, TiO, Si0 2 , B 2 0 3 , MnO) against oxidation and evaporation is protected.
- oxides A1 2 0 3 , MgO, CaO, TiO, Si0 2 , B 2 0 3 , MnO
- the heat treatment must be carried out in an oxidizing atmosphere. Under inert gas (acid-free atmosphere), although oxidation can be avoided, the zinc would evaporate due to the high vapor pressure.
- the corrosion protection layer according to the invention for the press-hardening process also has such a high mechanical stability that a forming step following the austenitizing of the sheets does not destroy this layer.
- the cathodic protection is at least significantly greater than the protective effect of the known anticorrosive layers for the press hardening process.
- a zinc alloy with a content of aluminum in weight percent of greater than 0.1 but less than 15%, in particular less than 10%, more preferably less than 5% on a Steel plate, in particular an alloyed steel sheet are applied, whereupon in a second step, the sheet is formed inline as a strand and heated upon access of atmospheric oxygen to a temperature above the Austenitmaschinestemperatur the sheet metal alloy and then cooled at an increased rate.
- a thin barrier phase is formed, in particular Fe 2 Al 5 _ x Zn x , which forms the Fe-Zn Diffusion in a liquid metal coating process, which takes place in particular at a temperature of up to 690 ° C., prevents.
- the sheet is formed with a zinc-metal coating with an addition of aluminum, which is effective only towards the sheet surface, as in the proximal region of the support an extremely thin barrier phase, which is effective against rapid growth of an iron-zinc compound phase, having.
- the metal layer on the sheet is first liquefied.
- the oxygenated aluminum from the zinc reacts with atmospheric oxygen to form solid oxide or alumina, resulting in a decrease in the aluminum metal concentration in this direction, which causes a steady diffusion of aluminum towards depletion, ie towards the distal region ,
- This accumulation of toner at the layer area exposed to air now acts as oxidation protection for the layered metal and as an evaporation inhibitor for the zinc.
- the aluminum is withdrawn from the proximal blocking phase by continuous diffusion towards the distal region, where it is available for forming the superficial Al 2 O 3 layer.
- the formation of a sheet metal coating is achieved, which leaves a cathodically highly effective layer with a high zinc content.
- the zinc alloy layer is applied to the sheet surface passing through a liquid metal bath at a temperature higher than 425 ° C, but lower than 690 ° C, especially at 440 ° C to 495 ° C, followed by cooling of the coated sheet, not only the proximal barrier phase can be effectively formed, or a very good diffusion inhibition can be observed in the region of the barrier layer, but it also takes place to improve the thermoforming properties of the sheet material.

- said layer ( Figure 9) consists of a gray appearing phase with a composition Zn / Fe of about 30/70 and out a bright area with the composition Zn / Fe of about 80/20.
- an increased aluminum content is detectable. Due to the detection of oxides on the surface can be concluded that a thin Al 2 0 3 protective layer is present.
- the annealed material has a potential of approx. -0.75 V. After a measuring time of approx. 1,500 seconds, the potential required for the resolution increases to ⁇ -0.6 V. The phase lasts up to a measuring time of approx. 2,800 seconds. Then the required potential increases to steel potential. In this case too, in addition to barrier protection, there is cathodic corrosion protection. The potential is up to a measurement time of 2,800 seconds at a value of ⁇ -0.6 V. Thus, such a material has thus over a very long time a cathodic corrosion protection.
- the potential time diagram is shown in FIG.
- This anticorrosive layer contains some aluminum in the zinc bath, of the order of about 0.13%.
- the profile component is heated to a temperature of about 500 ° C prior to austenitizing.
- the zinc layer is completely converted into Zn-Fe phases.
- the zinc layer is thus completely, that is converted to the surface in Zn-Fe phases. This results in zinc-rich phases on the steel sheet, all of which are formed with a Zn-Fe ratio of> 70% zinc.
- This anticorrosive layer contains some aluminum in the zinc bath, of the order of about 0.13%.
- the profile component with the aforementioned fully converted coating is inductively heated to> 900 ° C.
- the result is a yellow-green surface.
- the yellow-green surface indicates oxidation of the Zn-Fe phases during annealing.
- An aluminum oxide protective layer is undetectable. The reason for the absence of an aluminum oxide protective layer can be explained by the fact that in the annealing treatment the aluminum does not migrate as quickly to the surface due to solid Zn-Fe phases and can protect the Zn-Fe coating from oxidation. When heating this material at temperatures around 500 ° C is still no liquid zinc-rich phase, because this forms only at higher temperatures of 782 ° C. When reaching 782 ° C, thermodynamically there is a liquid zinc-rich phase in which the aluminum is freely available. Nevertheless, the surface layer is not protected against oxidation.
- the corrosion protection layer is already partially oxidized at this time and no opaque aluminum oxide skin can form any more.
- the layer is wavy ragged in cross-section and consists of Zn and Zn-Fe oxides ( Figure 11).
- the surface of said material is much larger due to the highly crystalline, acicular surface finish of the surface, which could also be detrimental to the formation of a covering and thicker aluminum oxide protective layer.
- the said, non-inventive coating forms a brittle layer, with numerous cracks, both across and is provided longitudinally to the coating. As a result, in the course of the heating, both decarburization and oxidation of the steel substrates can take place, especially with cold preformed components.
- a profile component made of a sheet metal with a galvanizing as in Example 3 is subjected after the roll forming a particular short, inductive heat treatment, at about 490 ° C to 550 ° C, the zinc layer is only partially converted into Zn-Fe phases.
- the process is carried out in such a way that the phase transformation is only partially carried out and therefore not yet converted zinc with aluminum on the surface is present and thus free aluminum as oxidation protection for the zinc layer is available.
- the profile component with the heat-treated coating according to the invention and only partially converted into Zn-Fe phases is subsequently heated inductively to the required austenitizing temperature.
- the result is a surface that is gray and without defects.
- a SEM / EDX examination of the transverse section (FIG.
- the cathodic corrosion protection is negligible with a voltage difference of 100 mV to the steel potential in poorly conducting electrolytes. Although there is still a cathodic corrosion protection even with a smaller difference to the steel potential, if a current is detected when using a steel electrode, but this is negligible for practical aspects, since the corrosive medium must conduct very well, so this contribution to the cathodic Corrosion protection can be used.
- cathodic corrosion protection in the context of the invention is subsequently determined that at 15 microns thick coatings and the process and experimental conditions described at least a cathodic corrosion protection energy of 4 J / cm 2 is present.
- a zinc layer which has been deposited electrolytically on the steel sheet surface is not in itself capable of providing a corrosion protection according to the invention, even after a heating step above the austenitizing temperature.
- the invention can also be achieved with an electrodeposited coating.
- the zinc can be deposited simultaneously with the oxygen-affine elements or elements in an electrolysis step on the sheet surface simultaneously, so that a coating with a homogeneous structure is formed on the sheet surface, which contains both zinc and the or the Sauerstoffäffinen elements. When heated to the austenitizing temperature, such a coating behaves like a coating of the same composition applied to the sheet surface in the hot-dip galvanizing process.
- a first electrolysis step only zinc is deposited on the sheet surface and in a second electrolysis step, the oxygen-affine element (s) is deposited on the zinc layer.
- the second coating from the clean material-affine elements can be significantly thinner than the zinc coating.
- the outer layer located on the zinc layer oxidizes from the oxygen-affine element (s) and protects the underlying zinc with an oxide skin.
- the oxygen affinity element or elements are selected so that they do not evaporate from the zinc layer or are oxidized in a manner that does not leave a protective oxide skin.
- a zinc layer is deposited electrolytically and then a layer of the oxygen or the oxygen elements is applied by vapor deposition or other suitable coating methods of non-electrolytic type.
- the anticorrosive coatings according to the invention were mentioned for profiling a profiled strand or for roll forming and the subsequent hardening of such a profiled strand or profiled strand sections.
- the coatings according to the invention or coatings chosen according to the invention for a sheet metal component which must be subjected to a heating step are also suitable for other processes in which a steel sheet is to be provided first with a corrosion protection layer and the steel sheet coated in this way is subsequently subjected to a heating step for curing is subjected to the same and prior to heating, during the heating or after heating, a transformation of the sheet is to take place.
- the fundamental advantage of the layer is that a heated component does not have to be descaled after heating and, moreover, that a very good cathodic corrosion protection layer with a very high corrosion protection energy is available. Whenever profiles or tubes are mentioned below, this also always refers to tubes, open profiles and generally rolled profiles.
- the profile component according to the invention is produced in that a band is first passed through a forward punch and then inserted into the profiling machine.
- the strip is bent to a desired profile.
- the necessary welding is carried out in a welding device.
- the heating device being, for example, an induction coil.
- the profile is heated at least partially to an austenitizing temperature necessary for hardening.
- the cooling takes place.
- a special cooling is used which prevents the partially liquid surface layer is fused. This causes high cooling rates with low fluid pressure.
- the induction heating device which serves to heat the sheet to the austenitizing temperature may be preceded by a further heating device which leads the sheet to the first heating stage at approximately 550 ° C.
- a further heating device which leads the sheet to the first heating stage at approximately 550 ° C.
- This can be, for example, an induction heating device to which - in order to comply with the necessary periods of time - an isolated region, for example an insulated tunnel region, is connected.
- the cooling is followed by a calibration device to which the heated and quenched profile strand undergoes a calibration, whereupon the profile strand is then cut to length with a cutting unit.
- band is drawn off from a strip preparation section and punched in a forward punch in a soft state and then profiled or bent and shaped accordingly in a profiling machine.
- a welding device may also follow the profiling.
- the thus preformed profile strand is then cut with a cutting unit or cutting device to the appropriate lengths and transferred to a profile memory with separation.
- a multiplicity of profiles in particular a multiplicity of profiles of different cross sections which are also formed differently, are stored. From the profile memory with separation the desired profiles are subtracted and fed via a drive roller set the hardness level.
- the individual profiles are heated with an inductive heating already described to the temperature necessary for curing and then quenched in the form already described, that is gently.
- the cured profiles can be retrofitted on a straightening scaffold.
- a heat treatment of the coating is carried out before heating to the temperature necessary for curing.
- the profile is first heated to a temperature necessary for the heat treatment in particular 550 ° C. This heating can be done relatively quickly in an inductive heating stage, wherein, if necessary, the heat of the component for a certain time in an insulating region, for example, an iso- tunnel through which the profiles are carried out.
- the profiled and finished molded profile strands are cut to standard profile lengths and then transferred to the profile memory with separation, the profile memory stores there exclusively tubes and profiles of a certain length, for example 6m. Depending on the required profile, the profiles are then removed individually and fed to the appropriate further treatment. Even with these profiles, if necessary, a hole pattern can already be arranged.
- the profiling and in particular the arrangement of the hole pattern can be such that the thermal expansion is fully taken into account during the heat treatment and / or heating to the temperature necessary for curing, so that the component after quenching with respect to the dimensional and Position tolerances is made accurately.
- a profile component made of sheet steel which has a cathodic protection against corrosion, which reliably remains even when the sheet is heated above the austenitizing temperature. It is also advantageous that the components do not have to be reworked after curing.
