[0002] The valve body is one of the essential parts of the high-speed train. In order to prolong its service life, it is often necessary to carry out anti-corrosion treatment. The traditional treatment process is: valve body blank—rough forging—precision grinding—chrome plating— Polishing-decoration-finished product, this kind of process can achieve a certain effect of improving hardness and anti-corrosion in principle, but using traditional processing, the product life is not good, and the corrosion resistance is less and less able to meet the current technical requirements. More importantly, pickling and hard chrome plating are required, which seriously pollute the environment

Embodiment Construction
[0019] The embodiments of the present invention will be further described below in conjunction with the accompanying drawings.
[0020] An anticorrosion treatment process for a motor vehicle valve body provided in this embodiment includes the following steps:
[0021] Step 1. Process the anti-corrosion treated valve body to the required size. No need to reserve deformation. The precision forged valve body can be directly processed to the required size. This process does not need to reserve deformation. At the same time, it greatly simplifies the post-treatment process of the valve body and saves the overall processing time of the valve body;
[0022] Step 2: Carry out shot peening treatment on the surface of the valve body; use a shot blasting machine to carry out high-strength ultra-fine shot peening on the surface of the valve body to remove forging burrs and improve the surface performance of the valve body. The shot blasting machine is a prior art, here No specific elabor...

The invention particularly relates to a surface anticorrosion treatment process for a valve body of a motor car. The process comprises the following steps that the valve body for being subjected to the anticorrosion treatment is machined to the demand size, the shot peening treatment is conducted on the surface of the valve body, activating is conducted on the valve body surface after the shot peening treatment, the non-metal element composite seeping is conducted on the activated valve body surface, and the oxygen atom composite seeping is conducted on the valve body surface after seeped withthe non-metal element; and cooling is conducted on the insulated valve body, washing is conducted on the valve body surface during cooling to the room temperature, the shot peening treatment is conducted on the surface of the valve body again, the oxygen atom composite seeping is conducted on the valve body surface after the shot peening treatment again, and cooling, washing and lubricant feedingare conducted on the insulated valve body. According to the surface anticorrosion treatment process, by adjusting the valve body surface treatment process and working procedure, the surface treatmentis conducted on the valve body, the high corrosion resistance performance and the like can be achieved, the environmental protection is also achieved, and the heavy metal pollution cannot be caused.
