Electroplating is also known as electro-chemical plating, is an electrolytic process. In this process metal ions in an electrolyte solution are deposited onto a cathode. In the electrolytic process, anode is generally made of metal being plated so it serves as source of coating metal. Workpiece where coating is to be applied made as cathode.

ELECTRO CHEMICAL MACHINING Introduction: The process of metal removal by electro chemical dissolution was known as long back as 1780 AD but it is only over the last couple of decades that this method has been used to advantage. It is also known as contactless electrochemical forming process. The noteworthy feature of electrolysis is

Hybrid production/manufacturing means the combination of processes/machines in order to produce parts in a more efficient and productive way. A general objective of hybrid manufacturing is the ''1 + 1 = 3''effect,meaning that the positive effect of the hybrid process is more than the double of the advantages of the single processes.

Electrodeposition is an electrochemical process that allows the preparation of solid deposits on the surface of conductive materials. It is a commercially highly relevant process, providing the basis for many indus-trial applications, such as electro-winning, refining, and metal plating. Metal plating is …
