Factors influencing the effect of electroplating

When plating, the plating metal or other insoluble material is used as the anode and the workpiece to be plated as the cathode, and the plating metal cations are reduced on the surface of the workpiece to be plated to form the plating layer. In order to exclude the interference of other cations and to make the plating layer uniform and solid, it is necessary to use a solution containing plating metal cations as plating solution to keep the concentration of plating metal cations constant.

Main salt system: Each type of plating will develop a variety of main salt system and its matching additive system, each system has its own advantages and disadvantages;

Additives: Additives include gloss agents, stabilizers, softeners, wetting agents, low zone walk agents, etc. The quality of the plating layer differs greatly when using additives made by different manufacturers;

Plating equipment: Plating equipment mainly includes hanging tools, mixing equipment, power supply, etc. Square hanging tools are used in conjunction with square plating tanks, while round hanging tools are used in conjunction with round plating tanks. Round plating tank and hanging device are more conducive to ensure uniform current distribution; stirring device can promote the flow of solution, make the solution state evenly distributed, and eliminate the stay of bubbles on the surface of the workpiece. DC power supply, good stability and small ripple coefficient. These choices will affect the final product out of the surface effect;

Process parameters: process parameters mainly include temperature, plating solution pH, plating solution composition, these parameters should be tested as required, not up to the requirements to be adjusted as soon as possible, otherwise it will certainly affect product quality;
