What is hard chrome plating? TWI
Hard chrome plating is an electroplating process in which chromium is deposited from a chromic acid solution. Thickness of hard chrome plating ranges from 2 to 250µm. Various types of hard chrome include microcracked chromium, microporous chromium, porous chromium and crack free chromium.

Zinc Plating Process Sciencing
Zinc plating, a process also known as galvanization, is the deposition of a thin layer of aluminum onto a metal component to provide a protective layer. The outer surface of the zinc coating oxidizes to form zinc oxide, which results in a matte silvercolored finish. Zinc plating is often applied to iron or steel

What is Metal plating? A Look at the Metal Plating Process
20191121&ensp·&enspThe plating process is a manufacturing process in which a thin layer of metal coats a substrate. Metal plating provides many benefits to products made from metal and other materials. This can be achieved through electroplating, which requires an electric current, or through electroless plating, which is in autoalytic chemical process.
