化学镀镍稳定性好,镀层硬度高,厚薄均匀,抗腐蚀能力强,耐磨性能好,且设备简单,操作方便。在设备维修中作为一种零件的修复手段,可以缩短修理周期,提高修复件的质量,减少修理费用。本文就我们在生产实际中的应用情况,作一介绍。化学镀镍的原理在设备维修中,一般使用酸性镀液,所需化学药品少,施镀方便。在含有镍离子及次磷酸根的溶液中,在表面催化作用下,利用强还原剂次磷酸根将镍离子还原成金属镍,次磷酸盐分解析出的磷沉积在镀件表 Electroless nickel plating has good stability, high hardness coating, uniform thickness, strong corrosion resistance, good wear resistance, simple equipment and convenient operation. In the equipment maintenance as a part of the repair tools, you can shorten the repair cycle, improve the quality of repair parts, reduce repair costs. This article gives an introduction of our application in production practice. The principle of electroless nickel plating equipment maintenance, the general use of acid bath, less chemicals required, plating convenient. In a solution containing nickel ions and hypophosphite, under surface catalysis, nickel ions are reduced to metallic nickel by using a strong reducing agent hypophosphite, and phosphorus deposited by the hypophosphite is deposited on the surface of the plating material
