Electroplating is how, precautions have those

It is the process of plating a thin layer of other metals or alloys on the surface of certain metals using the principle of electrolysis. Electroplating, the plated metal as the anode, oxidized into cations into the plating solution; to be plated metal products as the cathode, the plated metal cations in the metal surface is reduced to form the plated layer. In order to exclude the interference of other cations and to make the plating layer uniform and firm, it is necessary to use the solution containing the cations of the plating metal as the plating solution to keep the concentration of the cations of the plating metal unchanged. The purpose of electroplating is to coat the substrate with a metal deposit to change the surface properties or dimensions of the substrate. Plating can enhance the corrosion resistance of the metal (plated metal mostly corrosion-resistant metal), increase the hardness, prevent abrasion, improve electrical conductivity, lubrication, heat resistance, and surface aesthetics. Plating is divided into hanging plating, roll plating, continuous plating and brush plating and other ways, mainly with the size of the plated parts and batch related. Hanging plating is suitable for general size products, such as automobile bumpers, bicycle handlebars and so on. Roller plating is suitable for small parts, such as fasteners, washers, pins, etc. Continuous plating is suitable for batch production of wire and strip. Brush plating is suitable for partial plating or repair. Plating solution is acidic, alkaline and add chromium composite acidic and neutral solution, no matter what kind of plating method, with the products to be plated and the plating solution in contact with the plating tanks, hangers, etc. should have a certain degree of universality.

The plating is divided into two categories: decorative protective plating and functional plating.
