Autocalytic Plating

autocalytic plating: When the surface of the workpiece with a certain catalytic effect is in contact with the electrolyte solution, and in the absence of external current, the reduction characteristics of chemical substances are used to promote the deposit of related substances on the surface of the workpiece, and then the formation of a solid plating layer with the matrix, this process is called electroless plating, typical such as electroless nickel plating, electroless copper plating, etc. In particular, on the surface of the activated substrate, the metal ions in the plating solution are subjected to catalytic reduction to form a metal coating. Compared with electroplating, electroless plating has the advantages of better coating uniformity and uniform deposition on complex shape workpieces, and is suitable for precision parts with demanding coating quality.
