表面处理是应用范围极为广泛的一门应用科学,国外近几年的发展非常迅速。在机械工业里不仅应用在防护-装饰性镀层方面,例如电镀光亮性镍、微孔隙铬、微裂纹铬等,而且还较多地用来产生具有减摩、耐磨、耐热、光学、钎焊性、磁性等特殊用途的表面。最近较新的发展还有离子镀、化学气相沉积、分散电镀、局部电镀(Dalic法)、工程性电镀镍、有机复盖层等。随着机械工程的发展,不但继续通过表面处理提高材料在室内与一般大气中的防护-装饰性能、抗蚀性能,而且正在解决工业大气、湿热、干热、海洋性气候、强腐蚀介质中的保护问题。表面处理不仅进一步完善了钢铁零件的保护工艺,而且也解决了轻金属、难熔金属、粉末冶金、塑料制品等方面的处理技术和复涂工
Surface treatment is a very broad application of an applied science, foreign rapid development in recent years. In the machinery industry is not only used in protective - decorative coatings, such as plating bright nickel, micro-pore chromium, micro-crack chromium, but also used to produce a more friction, wear resistance, heat resistance, optical, solder Solder, magnetic and other special purpose surface. More recent developments include ion plating, chemical vapor deposition, dispersion plating, local electroplating (Dalic method), engineering nickel plating, and organic overlays. With the development of mechanical engineering, not only continue to improve the material through the surface treatment in the indoor and the general atmosphere of the protection - decorative performance, corrosion resistance, and is addressing the industrial atmosphere, hot and humid, dry heat, marine climate, strong corrosive medium Protection issues. Surface treatment not only further improve the protection of steel parts process, but also to solve the light metal, refractory metal, powder metallurgy, plastic products and other aspects of the processing technology and re-coating
