Electro-Coating's success of chromium plating – also known as hard
chrome plating, engineered chrome plating, or industrial chrome plating in
Industrial applications is attributed to its unique combination of multiple
properties and benefits not possessed by any other one material available
commercially. In many instances, all these properties are important for
successful commercial applications.
The properties of chromium are most desirable as metal coatings due to
their inherent protective and decorative characteristics. Chromium
deposits with excellent adhesion to a variety of base metals. It has a
pleasing bluish-white color and is highly resistant to oxidation or
tarnishing, contributing to its popularity as a decorative coating. In
addition, hardness, wear resistance and low co-efficient of friction are the
properties that make chromium of value in practically every major
industry. When identified as industrial hard chrome, it is differentiated
from decorative applications, and is primarily applied to a substrate
material for the purpose of wear resistance.

Hard Chrome Plating
WHAT IS INDUSTRIAL HARD CHROME?
The electrolytic deposition of chromium to the surfaces of other materials, primarily metals, occurs when electrical energy supplied to electrodes in a solution consisting primarily of chromic acid is converted to chemical energy to produce chromium metal.Frequently, when expensive machined parts are damaged or worn and no longer functional, hard chrome plating can be used to build up the lost metal and the parts can then be ground to their original tolerances. In many cases the wear life will have improved.
On new parts hard chrome is used to improve the durability of a variety of components of industrial equipment. The printing industry makes use of copper engraved plates and cylinders which are hard chrome plated for corrosion and wear resistance. Oil exploration equipment and production machinery of all types have many of their component parts chrome plated to extend their in-service life and to reduce costly downtime. Hydraulic equipment utilizes chrome plated shafting to extend service life in corrosive industrial environments.
