Abstract

The invention discloses a preparation process of a corrosion-resistant automobile hub. The preparation process includes the following steps that the automobile hub is selected for preparing required raw metal materials, the raw metal materials are smelted, a solution is filtered, then the solution is molten to form a mixed solution, the mixed solution is casted in a processed automobile hub mold,then the processed automobile hub mold moves in a film laminator for integrated pressing and molding, after natural cooling, the molded automobile hub is placed at 300-400 DEG C again for heat treatment, after being subjected to heat treatment, the automobile hub is subjected to rounding, surface grinding and surface treatment, then the automobile hub is placed in a pretreated electrophoresis tank, electrophoresis liquid is added in the electrophoresis tank, then electrophoresis is conducted, and finally, the surface of the automobile hub is coated with a layer of corrosion-resistant coating.After long-time use, the hub can not be corroded, the hub can adapt to environments different in temperature, the service life of the hub is prolonged, and the hub meets the current development requirement.

Description

technical field

[0001] The invention relates to the technical field of automobile parts preparation, in particular to a preparation process of a corrosion-resistant automobile wheel hub. Background technique

[0002] With the rapid development of the economy, the output and usage of cars are increasing, and consumers are paying more and more attention to the quality of cars, and car wheels are an indispensable part of cars. has a pivotal role. Since the wheel hub is outside the car, it is easy to corrode the wheel hub after being exposed to wind and sun for a long time, thus affecting its safety performance. Therefore, we propose a preparation process for corrosion-resistant automotive wheel hubs. Contents of the invention

[0003] The present invention proposes a preparation process of a corrosion-resistant automobile wheel hub to solve the problems raised in the above-mentioned background technology.

[0004] The present invention proposes a kind of preparation technol...
