Problems solved by technology

However, chromium is a heavy metal with high toxicity. When it enters human cells, it will cause damage to liver, kidney and other internal organs and DNA, resulting in cancer.
Therefore, the pollution caused by the preparation of chromium metal coatings in the traditional electroplating process is relatively serious.

Abstract

The invention discloses a process method for preparing a high-hardness corrosion-resistant hub coating. The process method comprises the following steps of preparing AlxFeNiSiTi high-entropy alloy powder; mixing the AlxFeNiSiTi high-entropy alloy powder and stainless steel blasting shots in proportion, and heating the mixture to the preset temperature after uniform mixing; and spraying the AlxFeNiSiTi high-entropy alloy powder and the stainless steel blasting shot to the surface of a wheel hub through inert gas, and uniformly attaching the AlxFeNiSiTi high-entropy alloy powder to the surface of the wheel hub along with movement of a spray head to form the coating. According to the process method, a coating material can be better attached to the surface of the wheel hub, the adhesion and density of the coating material are improved, and meanwhile, some surface defects of the wheel hub can be repaired; and the content of Al in AlxFeNiSiTi high-entropy alloy can be changed according to different wheel hubs and different use conditions, so that the hardness and corrosion resistance of the AlxFeNiSiTi high-entropy alloy are adjusted.

Description

technical field [0001] The invention relates to the technical field of automobile hubs, in particular to a process for preparing a high-hardness corrosion-resistant coating for hubs. Background technique [0002] In recent years, with the development of aluminum alloy preparation technology, high-performance aluminum alloy wheels have gradually replaced steel wheels and entered the market. Compared with steel wheels, aluminum alloy wheels have higher strength, lower density, and better heat dissipation, so their applications are more extensive. However, the corrosion resistance of aluminum alloy wheels is relatively poor and its hardness is relatively low. Therefore, no matter in processing and production or in actual use, various defects will inevitably appear on the surface of aluminum alloy wheels. Therefore, surface treatment for its hardness and corrosion resistance is very important for improving the performance and life of aluminum alloy wheels. [0003] For the sur...
