Reasons for electroplating include making the object more corrosion resistant, strengthening the surface, producing a … The metallic ions of the salt carry a positive charge and are attracted to the part. Improper cleaning usually results in a variety of plating defects like peeling or blistering over a period of time. Electroplating occurs when an electrically conductive object is coated with a layer of metal using electrical current. Electroplating consists of depositing a thin layer of metal on another metal, either to protect the surface from corrosion or for a decorative effect. This process of producing chemical changes by passing an electric current through an electrolytic cell is called electrolysis. can be defined as the mass of the substance deposited/liberated per unit charge. Electroplating is a plating process that uses electrical current to reduce cations of a desired material from a solution and coat a conductive object with a thin layer of the material, such as a metal. Definition: Chromium is a kind of silver-white metal with a blue tint. Electroplating is the process of plating one metal onto another by hydrolysis, most commonly for decorative purposes or to prevent corrosion of a metal. Although the basic principles of electroplating are known for several decades, practical electrodeposition in micro-vias is quite complicated [38–42].
