Description
Technical Field
The invention belongs to the field of steel plate processing, and particularly relates to a plated hot-formed steel plate, a hot-stamped part with excellent adhesive property, a manufacturing method and application.
Background
Due to the requirements of light weight and corrosion resistance, automobile parts use a large amount of high-strength coating hot-formed steel. Among coated hot formed steels, aluminum-based plated hot formed steel sheets are widely used.
Automobile parts are generally required to be connected with each other, and an adhesive technique is widely used for connection between the automobile parts as one of connection techniques. Thermoformed parts also often require the use of adhesives for bonding. When adhesive bonding is performed, the desired adhesive joint failure mode is glue-to-glue tearing (cohesive failure, fig. 1), while inter-plating tearing rather than glue-to-glue tearing (interfacial failure, fig. 2) is likely to occur when bonding due to the inevitable inter-plating cracks of the general aluminum silicon plated hot-formed steel parts, resulting in a decrease in adhesive performance.

The method for obtaining the aluminum alloy coating on the steel plate comprises the following steps: carrying out hot dip coating on the steel plate in a hot rolling state or annealing state to obtain an aluminum alloy coating to obtain an aluminum alloy coated steel plate;
namely, the aluminum alloy plating layer is obtained by the following method: the steel plate is subjected to hot rolling → acid cleaning → hot dipping → flattening to obtain a hot-base aluminum alloy plated steel plate;
or the aluminum alloy plating layer is obtained by the following method: the steel plate is subjected to hot rolling → pickling → cold rolling → cleaning → annealing → hot dip coating → leveling to obtain the aluminum alloy coated steel plate.
In the aluminum alloy coating components, Si can form an Fe-Al-Si inhibition layer on the surface of the steel plate and can effectively inhibit brittle phase Fe2Al5Thereby improving the adhesion of the plating layer. When the Si content is lower than 2.5%, the Fe-Al alloy layer becomes thick, the coating adhesiveness is reduced, when the Si content is higher than 7.0%, the surface quality of the coating is influenced, and according to the condition, the Si content in the coating is controlled to be 2.5-7.0%. Zn: the inventors found that zinc oxide formed by thermal oxidation of the plating layer has an effect of improving adhesive properties under specific conditions, that when the content of Zn is less than 15%, its oxide does not occupy a sufficient proportion on the surface after hot forming, that improvement of adhesive properties is insufficient, and that when it exceeds 25%, LME phenomenon is easily generated at the time of hot forming. At the same time, the control of the subsequent hot forming process is needed to control the formation of the oxide layer, and the effect of improving the adhesive property is not obtained when the formed oxide cannot occupy a sufficient proportion on the surface or a loose and thick oxide layer is formed. Mg: the magnesium oxide is added for improving the corrosion resistance, the content is not higher than 2.0 percent, otherwise, local blackening of a raw coil and a plate is easily caused to cause color difference of parts after hot forming, and simultaneously, the magnesium oxide is more easily enriched on the surface during hot forming to cause reduction of the adhesive property.
The surface treatment layer comprises one or more organic acid zinc; the organic acid zinc includes but is not limited to zinc succinate, zinc adipate, zinc tartrate, zinc acetate, zinc oxalate, zinc malate and zinc citrate. When the aluminum alloy plating layer has a surface treatment layer thereon, the plating layer is prevented from contacting air to prevent oxidation of the plating layer, and then subjected to a heat treatment process equivalent to sintering, and subjected to mold hot pressing and cooling to form a zinc oxide layer. The use of the surface treatment layer allows the thermoforming process to have a wider process range in which the adhesive properties can be ensured, particularly without the need to control the temperature and humidity of the working environment.
The surface treatment layer is prepared by coating an aqueous solution or turbid emulsion containing organic acid zinc on an aluminum alloy layer, and heating and drying.
The coating amount of the surface treatment layer is 0.1-0.5g/m in terms of zinc content2The content is less than 0.1g/m2The zinc oxide after hot forming is difficult to completely cover the surface of the coating, can not completely prevent the contact between the adhesive and the aluminum alloy coating, has insufficient improvement on the adhesive performance, and has the content of more than 0.5g/m2In this case, a thick, multilayered zinc oxide layer having insufficient interlayer bonding force is formed, and the adhesion property is lowered.
The organic acid zinc is used as a surface treatment layer, and the surface treatment layer does not contain any organic resin binder, and particularly does not contain NO generated during heatingXAn N element-containing organic resin which is a harmful gas. The absence of resin enables to obtain a treated layer having a smaller thickness, preventing the treated layer from forming a thicker zinc oxide layer after heating to lower weldability, and preventing the loose zinc oxide layer from being peeled off at the time of adhesion to lower adhesion property.
The rust preventive oil layer is formed by coating rust preventive oil on the aluminum alloy plating layer or the surface treatment layer, the rust preventive oil is coated for temporary rust prevention and prevention of plating layer scratching in blanking, the coating amount does not affect the adhesive performance effect of the invention because it is decomposed in thermoforming, and the adhesion amount of the rust preventive oil is preferably 0.5-2g/m2。
The hot stamping part with excellent adhesive property provided by the invention is produced by hot forming the plated hot forming steel plate.
The invention provides a manufacturing method of a hot stamping part with excellent adhesive property, which comprises the following steps: and heating the plated hot-formed steel plate to the austenitizing temperature of the steel plate, and then carrying out hot press forming to obtain the hot-stamped part.
The manufacturing method specifically comprises the following steps: the steel plate is hot-formed by utilizing the coating of the invention, then the plate is cut to obtain a blank, the blank is heated to 840-950 ℃, the heat is preserved, and then the blank is transferred to a hot stamping tool for hot stamping.
When the blank adopts the aluminum alloy coating on the steel plate of the coating hot forming steel plate or the aluminum alloy coating and the antirust oil layer on the steel plate, the manufacturing method specifically comprises the following steps: the blank is heated to 840-950 ℃ in the atmosphere containing 15-25% volume fraction oxygen, the heat preservation is carried out for 3-8 minutes, the heating time is short, the complete austenitizing of the steel cannot be ensured, and the production efficiency is reduced after 8 minutes.
When the thickness of the blank is less than 1.4mm, keeping the temperature for 5-8 minutes;
alternatively, when the blank thickness is less than 1.4mm, the preferred holding time for efficiency purposes is 3-4min and the blank is transferred from the furnace to the die gap and the blank is purged with a dry gas containing 15-25% volume fraction oxygen for 1-5 s. Due to the short heating time, the surface zinc oxide is generally not sufficiently formed to ensure the adhesive properties after thermoforming. The inventors have realized that the formation of an oxide layer is not only related to the heating time, but also to the oxygen content and humidity of the furnace atmosphere, and that the distribution of oxides can be adjusted by increasing the oxygen partial pressure and humidity of the furnace atmosphere, whereas increasing the air humidity increases the risk of hydrogen embrittlement, and increasing the oxygen partial pressure also causes an increase in costs. Thus, when the thickness of the billet is less than 1.4mm, it is preferable to purge the billet for 1-5s with a dry gas containing 15-25% by volume of oxygen in the gap between the billet and the die in order to promote oxidation of the coating and make zinc oxide occupy a sufficient proportion on the surface, and another additional effect of this is to rapidly solidify the coating surface in the molten state and reduce the adhesion of the coating on the die;
when the thickness of the blank is more than or equal to 1.4mm, the preferable heat preservation time is 5-8min, zinc oxide is fully formed on the surface, and the purging step can be omitted for the purpose of adhesive property.
When the blank adopts the aluminum alloy coating and the surface treatment layer on the steel plate of the coating hot forming steel plate or the aluminum alloy coating, the surface treatment layer and the rust-proof oil layer on the steel plate, the blank is kept at 840-950 ℃ for 3-12min, the heating atmosphere is not required, and the blank can be carried out in any atmosphere; the complete austenitization of the steel cannot be guaranteed in a short time, the surface treatment layer prevents the oxidation of the plating layer, and the surface treatment layer is cracked into an oxidation layer, so that the upper limit of the heating time is not required to be limited for the purpose of the adhesive property, however, the heating time is not more than 12min generally for the purpose of efficiency, and meanwhile, the atmosphere of a heating furnace and the blank after heating are not required to be limited, so that the production process is simpler and more convenient.
The hot stamping specifically comprises the following steps: and transferring the heated blank to a hot stamping tool, carrying out hot stamping on the blank at the temperature of 500-700 ℃, wherein the purpose of hot stamping at the temperature of below 700 ℃ is to inhibit liquid metal cracks (LME), and forming at the temperature of below 500 ℃ has certain difficulty.
After hot stamping, the obtained part is cooled either in the tool itself or after transfer to a special cooling tool, obtaining a hot formed part with excellent adhesive properties.
