汽车工业采用了堆焊、气体火焰喷涂、真空施镀等方法来提高零件和工具的耐磨性。目前,正在研究真空离子——等离子工艺。真空离子——等离子喷涂工艺之所以能获得长远发展,是因其具有下述优点:1可大大延长处理件的寿命(单位层厚的寿命);2可减少摩擦损失,提高机械效率;3施镀材料消耗少(约1克/分米~2);4可用相对富有的材料,如镀钛;5在增加寿命的情况下,可保证有较高的生产率(在施薄镀层时也能增加寿命的情况下),能适用于大量生产;6多数情况下无需对硬质镀层进行机械加工;7可将离子——等离子设备装在生产线上;8不存在生态问题,生产环境卫生(解决清冼问题之后)。然而,如果对镀层摩擦、磨损和老化特性没有充分的研究,就会阻碍摩擦零部件的真空——离子的耐
The automotive industry used surfacing, gas flame spraying, vacuum plating and other methods to improve the wear resistance of parts and tools. Currently, vacuum ion-plasma processes are being studied. The reason why the vacuum ion-plasma spraying process can achieve long-term development is that it has the following advantages: 1. It can greatly prolong the service life of the processing member (unit life of the layer thickness); 2. It can reduce the friction loss and improve the mechanical efficiency; Less material consumption (about 1 g / dm2); 4 Relatively rich materials such as titanium; 5 Increased life expectancy ensures higher productivity (also increases with thin plating) Longevity), suitable for mass production; 6 No mechanical processing of hard coatings is required in most cases; 7 Ion-plasma equipment can be installed on the production line; 8 There is no ecological problem, production sanitation Sin problem). However, insufficient study of the friction, wear and aging properties of the coating will hinder the vacuum-ion resistance of frictional parts
