Definitions
- the present invention relates to corrosion resistant coatings of guide rolls for conducting screens or felts in papermaking machines.
- US-A-5,283,121 discloses a method of applying an anticorrosive coating to the metal body of a paper machine roll wherein the surface of the body is provided with a thermal spray coating of a stainless steel material and a layer of fluoropolymer applied to the surface of the thermal spray stainless steel coating.
- the anticorrosive coating of rolls or roll cores currently uses galvanic hard chrome layers and hard metal layers applied by thermal spraying.
- the galvanic chrome plating offers cost-effective and effective corrosion protection, but is due to the toxicity of the galvanic baths used to classify as polluting process.
- a mechanical cleaning of hard chromium plating is difficult due to the brittle behavior of chromium.
- hard metal coatings usually a composite material embedded in a cobalt-nickel matrix tungsten carbide hard materials is used, which with a thermal spraying method, such as. B.
- HVOF H IgH V elocity- O xygen- F uel, high velocity flame spraying
- the application of thermal hard metal spray coatings takes place in several strokes, ie in several sub-layers to ensure the physical homogeneity of the coating.
- Thermally sprayed hard metal coatings are characterized by good corrosion protection and high abrasion resistance.
- the adhesion of impurities arising during a paper production is comparatively low on hardmetal surfaces, so that they are relatively easy to clean by Beschabtation.
- the production of thermal hard metal spray coatings is very expensive compared to the chrome plating.
- Corresponding corrosion protection can be achieved with a method according to claim 1 comprising steps of providing a thermal spray coating apparatus, providing a stainless steel material, coating at least a portion of the surface of the guide roll by applying the stainless steel material using the thermal spray coating apparatus and sealing the applied coating with a polymeric material comprising an epoxy resin.
- An inexpensively and environmentally produced corrosion-resistant guide roll according to claim 16, comprising a metallic base body, a thermal spray coating of a stainless steel material covering at least a portion of the surface of the metallic base body and a polymeric sealing layer applied to the surface of the thermal spray stainless steel coating polymeric sealant layer comprises an epoxy resin.
- the provided thermal spray coating apparatus is configured to perform high velocity flame spraying or laser spraying. These thermal spray processes do not lead to any significant metallurgical change of the spray material, so that the metallurgical Composition of thermal spray coatings prepared by these methods corresponds to the starting material used for the coating.
- the stainless steel material used as the starting material for the coating is provided in the form of fine powder whose particles plastically deform on impact with the surface to be coated, whereby very dense layers of low porosity can be produced in a simple manner.
- the provided apparatus for thermal spray coating for performing arc spraying is formed in which the coating starting material is melted in an arc and transferred by means of a carrier gas to the workpiece to be coated.
- Arc spraying is particularly suitable for applying very well-adhering layers with thicknesses of more than 200 microns to several millimeters on large surfaces.
- the stainless steel material is preferably provided in wire form for ease of feeding.
- a stainless steel material is preferably used, which is formed by a chromium-nickel steel having a composition according to one of the material numbers 1.4401, 1.4404, 1.4406, 1.4435, 1.44036 or 1.4440.
- Stainless steels of this material number also meet the standards 316 L and 316 of the American Iron and Steel Institute (AISI).
- AISI American Iron and Steel Institute
- Very dense, low-porous coatings are advantageous by applying the stainless steel material on a surface of the roll component in several strokes, ie by means of achieved several successive successive deposited sublayers. Dense thermal coatings with thicknesses of about 50 to 200 ⁇ m can already be achieved with 4 to 6 strokes.
- the further material being a carbide, boride or nitride or a mixture thereof or a mixture can be with a metal of the 4th, 5th or 6th subgroup.
- the coating can be applied by the same coating methods as the stainless steel layer, wherein the thickness can be a further 1 to 3 strokes. As a result, a coating which, although not closed, but serving at least one compacting purpose, is formed on the stainless steel, which ensures increased corrosion resistance.
- the polymeric material for sealing the spray coating comprises an epoxy resin, which wets a stainless steel surface in the non-crosslinked as well as in the partially crosslinked state well and thus guarantees a solid cohesive connection. Furthermore, the good wettability also ensures that the resin penetrates into the recesses of the surface and completely fills it, so that no voids form at the interface of the spray coating with the polymeric sealing layer.
- the polymeric material for sealing the sprayed coating comprises a silicone-polyester resin which combines good wetting of stainless steel sprayed layers with a non-stick and dirt-repellent action.
- fillers can also be embedded in the polymeric material of the sealant layer for improvement the non-stick and dirt-repellent properties to achieve their surface.
- materials which contain polyfluoroethylene and in particular polytetrafluoroethylene are preferably used for the fillers.
- the fillers in the form of particles and in particular in the form of particles with average diameters in the range of 0.1 to 5 microns are embedded in the polymeric base material of the seal.
- Figures 1A and 1B is for illustrative purposes only and does not represent a representation of a real component. Sizes and ratios of the individual components are therefore selected with regard to a clear presentation of the circumstances and differ from those of an actual embodiment.
- FIG. 1A shows a detail of a roll component 10 provided with a corrosion-protected surface.
- the illustrated embodiment of a roll component has a roll core 1, on the surface of which a corrosion protection layer 5 formed by a spray coating 4 and a seal 3 applied thereon is arranged.
- the anticorrosion layer 5 preferably covers all Surface areas of the roll component 10, which are exposed to the corrosive media occurring during normal use of the roller.
- the spray coating 4 is constructed in the illustrated embodiment of individual stainless steel particles 2, which adjoin one another positively to form a closed and thus dense layer.
- a suitably corrosion-protected roller is suitable for use as a guide roller for screens or felts in papermaking machines.
- the stainless steel material of the spray coating 4 is preferably a stainless chromium-nickel steel having a composition according to one of the material numbers 1.4401 (short name: X5CrNiMo17-12-2), 1.4404 (short name: X2CrNiMo17-12-2), 1.4406 (short name: X2CrNiMoN17-11 -2), 1.4435 (short name: X2CrNiMo18-14-3), 1.4436 (short name: X3CrNiMo17-13-3) or 1.4440 (short name: X2CrNiMo19-12), which are distinguished by their high resistance to corrosion and acids.
- the steel types mentioned also meet the standards 316 and 316 L of the American Iron and Steel Institute (AISI).
- a thermal spraying method is preferably used, the basic steps in FIG. 2A are presented.
- Thermal spray coating is to be understood as a surface coating process in which the coating material is ab-, on or melted and accelerated as a spray particle is accelerated via a gas stream in the direction of the surface to be coated.
- the surface of the workpiece to be coated is only slightly thermally loaded. When hitting the workpiece surface, the spray particles are usually flattened and connect by mechanical clamping. As a result, crack-free coatings with a homogeneous microstructure, low porosity and good bonding to the workpiece can be achieved.
- the melting of the wire-shaped spray or coating material is performed with an electric arc
- the high-speed flame spraying is the melting of the spray material particles in the fuel-oxygen high-velocity flame and laser spraying with the laser beam.
- other than the exemplified thermal spray coating methods may be used.
- step S2 of the in FIG. 2A illustrated method for applying a corrosion protection coating on a roll component of the spray material is provided in the form of a stainless steel material, preferably using stainless stainless steels, such as chromium-nickel steels of AISI standard 316 L or 316, which also with the material numbers 1.4401, 1.4404 , 1.4406, 1.4435, 1.44036 or 1.4440.
- the form in which the spray material is provided depends on the device used for coating. In arc spraying, the coating material is provided, for example, in wire form, in high-speed flame spraying in powder form.
- the order of magnitude of the average particle sizes of such powders is selected as a function of the desired coating thickness and can be, for example, about 50 ⁇ m for coating thicknesses of approximately 100 to a few 100 ⁇ m, since the particles are flattened when they hit the workpiece surface.
- a surface or a part of a surface of the workpiece 10 is coated with the spray material using the apparatus.
- the application of the spray material is preferably carried out in several strokes.
- the number of strokes was determined by the process parameters set on the coating apparatus, possibly the size of the powder particles, the distance between the workpiece and the part of the apparatus emitting the spray material and the desired coating thickness. Usually, the number of strokes is determined experimentally.
- the porosity of the sprayed coating can also be influenced by the process parameters of the coating process, whereby porosities of less than 0.5% can be achieved, in particular with high-speed flame spraying. By porosity here is the area fraction to be understood, which is taken in a penetrating the investigated material transverse grinding of the cavities contained therein.
- step S3 The stainless steel sprayed coating applied in step S3 is finally sealed in step S4 by application of a polymeric material, whereupon the corrosion protection coating process is completed in step S5, apart from possible surface finishing.
- Thermal spray coating processes are characterized by the possibility of producing coating layers with very low porosity, ie with few cavities formed in the coating material.
- the individual cavities are usually not connected to each other, so that the pores create no passages from the surface of the coating to the surface of the base material, via which a penetration of electrolytically acting substances could take place.
- coatings are therefore dense for the process water and vapors associated with papermaking.
- the coating surface is sealed with a polymeric material upon completion of the thermal spray coating.
- the sealing effect is not removed by a possible wear of the sealing layer 3 to the exposure of the upper regions of the spray coating 4, the surface of the spray coating is not ideally flat, but has a spatial contouring, in which the interfaces of adjoining coating particles arranged almost exclusively in depressions are.
- Suitable polymers are epoxy resins and epoxy resins with filler particles embedded therein, for example of a polyfluoroethylene (PFE) and in particular of polytetrafluoroethylene (PTFE). Since epoxy resin in the non-crosslinked or partially crosslinked state shows good wetting of the coating base material, it can also penetrate into depressions of the coating surface with an unfavorable aspect ratio. The viscosity of the epoxy resin can be reduced by the addition of solvents, such as alcohols or ketones, to adjust the wetting to the surface contour of the coating 4.
- the sealing process can be done by dipping, by spraying, or by using brushing tools such as a brush. As brushing or filling done.
- DJ2600 is applied a corresponding one of one of the AISI standard 316 L steel formed spray material in 4 strokes on the surface of a steel roller core to form an approximately 90 micron thick spray coating using a high-speed flame spraying apparatus "Diamond Jet Hybrid ®". The resulting thermal spray coating is then sealed with a colorless two-component epoxy resin-based system.
- FIG. 1B is in the same view as in Figure 1A a second embodiment of the invention shown.
- an additional second coating 6 is provided here, which is arranged on the spray coating 4 and provides the function of compacting the stainless steel particles 2. This embodiment is particularly suitable for use in highly loaded positions appropriate.
- carbides there are in particular carbides, nitrides or borides and mixtures thereof and mixtures with other metals of the 4th, 5th or 6th subgroup of the Periodic Table of the Elements application.
- a preferred embodiment is tungsten carbide.
- this hard metal layer does not form a dense, closed layer, it densifies the underlying layer due to the high density, for example of tungsten, in such a way that increased corrosion resistance can be assumed.
- the invention described enables effective, long-lasting and cost-effective corrosion protection of guide rolls for use in paper machines.
