In order to prevent corrosion of parts, corrosion-resistant materials such as nickel, chromium, zinc, etc. are often plated on the surface of metal parts, or oil is applied to the surface of metal parts, and anti-corrosive paint is applied on the surface of non-metal parts to prevent parts and Direct contact with hazardous media. The potential difference on the surface of the part can also be reduced by improving the surface finish of the part.
2, fatigue damage of parts
Form of expression: fracture, surface peeling
Treatment method: Improve the surface finish of the part during the manufacturing process, and use relatively gentle section filtering to reduce the stress concentration of the part. In addition, the use of carburizing, quenching and other methods to improve the hardness, toughness and wear resistance of the parts, can also receive good results.
3, the friction of the parts
In order to reduce the amount of abrasive wear, wear-resistant materials are used as much as possible on the working parts of agricultural machinery. When designing the shape of working parts of agricultural machinery, the frictional resistance is also minimized. For example, the use of high manganese content and rare earth alloys to produce soil-processed parts, the application of wear-resistant materials such as polyvinyl fluoride on the plow wall; the use of roller plows and soil sliding friction to roll friction, etc., are relatively reduced The amount of abrasive wear.
