1.Corrosion and damage of parts
In order to prevent the corrosion of parts, nickel, chromium, zinc, etc. are often used on the surface of metal parts, or oil is applied to the surface of metal parts, and non-corrosive paint is applied to the surface of non-metal parts to prevent parts and Direct contact with harmful media. By improving the surface finish of the part, the potential difference on the part surface can also be reduced.
2.Fatigue damage of parts
Manifestation: Fracture, surface peeling: Treatment method: Improve the surface finish of the part during the manufacturing process, and use a milder section filter 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 parts, can also receive good results.
3.Friction damage of 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 to stabilize the shape of the working parts of the soil mixing station, its friction resistance is also minimized. For example, the use of high manganese content and rare earth alloys in the manufacture of soil processing parts, the application of wear-resistant materials such as polyvinyl fluoride on the plough wall; the use of roller ploughs to change the sliding friction with the soil, etc. Abrasive wear.
