金属黑色化处理常用于某些零件和产品的表面装饰,以及改善金属表面的性能,如抗蚀性、抗磨损性和抗辐射性等。黑色化处理方法很多,随金属材料和使用场合的不同,采用不同的配方和操作工艺。总的可以分为二大类:有机涂层(漆、树脂和塑料)和无机黑色化(湿法:电沉积、化学氧化/着色、阳极化着色。干法:离子镀、气相沉积等)。这里主要介绍湿法黑色化处理。一、电化学法(电沉积和阳极化) 三氧化二砷、黑铬、黑镍(镍—钼合金)等黑色化工艺,在很多著作中都有叙述,虽然配方各有差异,但基本组成变化不
Blackening of metals is commonly used for the surface decoration of certain parts and products as well as for improving the properties of metal surfaces such as corrosion resistance, abrasion resistance and radiation resistance. Black processing methods, with the metal materials and the use of different occasions, using different formulations and operating processes. The general can be divided into two categories: organic coating (paint, resin and plastic) and inorganic black (wet: electrodeposition, chemical oxidation / coloring, anodizing coloring. Dry method: ion plating, vapor deposition, etc.). Here mainly introduces wet black process. First, the electrochemical method (electrodeposition and anodization) Arsenic trioxide, black chromium, black nickel (nickel - molybdenum alloy) and other black process, in many books have described, although the formulations are different, but the basic composition does not change
