coating of one metal over another metallic object with the help of electricity is known as
Answers
Answer: Electroplating
Explanation:
is a general name for processes that produce a metal coating on a solid substrate through the reduction of cations of that metal by means of a direct electric current.
Answer:
Electroplating and electroless plating
Electroplating is a process that uses an electric current to reduce dissolved metal cations so that they form a thin coherent metal coating on an electrode. Electroless plating, also known as chemical or auto-catalytic plating, is a non-galvanic plating method that involves several simultaneous reactions in an aqueous solution, which occur without the use of external electrical power. It is mainly different from electroplating by not using external electrical power. Plating an object makes it tougher and improves the corrosion resistance of the material. Electroplating and electrolessplating can be used to create a protective coating for materials that will be used in the medical field. Electroplating is quick and effective if the external power source is sufficient. The coat produced by this method is smooth and thick enough to protect the material from damage.
