Embodiment 1
[0041] A surface treatment process for mechanical parts, comprising the following steps:
[0042] 1) Parts degreasing
[0043] Use a degreasing agent or acetone to scrub with a brush or a scouring pad to remove local heavy oil stains on the surface of the parts;
[0044] 2) Parts washing
[0045] Use a high-pressure water gun tank to rinse the surface of the parts twice with pure water, and use high-temperature pure water for parts with heavy oil pollution at a temperature of 40 °C;
[0046] 3) Surface polishing
[0047] Put the parts and the medium into the drum of the planetary tumbling machine for tumbling. The mass ratio of the medium is 15% kerosene, 25% polishing agent, 50% steel shot, and 10% water, and the tumbling time is 30 minutes;
[0048] 4) chemical polishing
[0049] Use chemicals for rough polishing and fine polishing respectively, the chemical agent is a mixture of nitric acid and nitric acid, and the time is 5 minutes;
[0050] 5) Electrolyte plasma poli...
