Electroplating for hardware luggage accessories is already a very familiar thing, but also know that electroplating is only for hardware luggage accessories are metal material, that is not metal luggage hardware accessories to electroplating this action, how to solve it? That would require electroless plating. What is electroless plating? Electroless plating is the main process of non-metal plating. After activation treatment, catalytic active centers have been distributed on the non-metallic surface. These active centers serve as the crystal nuclei for the growth of chemical coatings, from which the chemical coatings grow into continuous coatings. After the initial coating is formed, the chemical coating has an autocatalytic effect that allows the electroless plating to continue.
The principle of electroless plating is still REDOX reaction. The ions participating in the reaction provide and exchange electrons to complete the electroless plating process. Therefore, the chemical plating solution needs to have a reducing agent that can provide electrons, and the gold-plated ions are of course oxidants. In order to control the plating speed, it is also necessary to have a complexing agent to stabilize the metal ions and a pH regulator (pH buffer) to provide the best reduction effect. Electroless copper plating and electroless nickel plating are the most widely used in non-metallic electroplating.
