Nickel plating is a method of depositing a layer of nickel on the surface of non-ferrous metal parts by means of electrochemical action.It can be used as a surface coating, but it is mainly used for chromium plating, to prevent corrosion, to increase wear resistance, gloss and beauty.It is widely used in machinery, instruments, instruments, medical devices, household appliances and other manufacturing industries.i will introduce the nickel plating process, nickel plating process conditions.
Nickel plating process: generally includes three stages: pretreatment before plating, plating and post-plating.
Nickel plating conditions
Nickel plating process can generally be divided into dark nickel and bright nickel. In addition, with the application and demand, it also extends to semi-bright and so on. Bright nickel is obtained from plating bath with brightener, while dark nickel is obtained from electrolyte without brightener. Common plating is also called dark nickel process. So what are the technological conditions for nickel plating? The following is an introduction to the process conditions for the formation of dark nickel and bright nickel.
First of all, the electroplating industry is a heavy pollution industry. A large number of toxic and harmful materials are used in electroplating. These materials will emit different degrees of gases in the process of storage and use. Some gases will stimulate people's eyes, nose, throat and skin and cause inflammation.
However, nickel has almost no acute toxicity. Generally, nickel salts are less toxic, but nickel carbonyl can produce very strong toxicity. Nickel carbonyl is quickly absorbed by the respiratory tract in the form of vapor, and also by the skin in a small amount. The former is the main way for poisons to invade the human body in the working environment.
So we must pay attention to safety protection in electroplating process.
