ELECTROPLATING
Introduction to Electroplating
Chrome plating is a form of electroplating where we make use of an electrical current to pull dissolved metallic chromium out of our plating bath and deposit it in a thin layer on the substrate — which is your product or material. Through precise bath chemistry and current flow control, we can deposit the right thickness of chrome plating for your application.
​
​
Chrome plating plant consists of :
​
o The electrolyte; which is the chemically engineered solution containing dissolved chromium
o The tub; it includes the chrome electrolyte
o The rectifier; it outputs an electricity flow of the high variable current required for the electroplating process
Pros of chrome plating
o Low convicted heat throughout the process, no deformation or cracking takes place
o Low coefficient for friction of the final product which resists galling, abrasive unlubricated wear
o Wear resistant, High hardness up to 65 HRC
o Is suitable for complex and irregular geometries, including holes and bores
o Adherence is excellent, meaning little risk of de- lamination or flaking during use
Chrome plating applications
o Build up to restore dimensions of undersized parts
o Hard facing
o Increasing service life of mechanical components
o Chrome can be applied to:
o Nickle based alloys
o Copper
o Steel
o Carbon steel
o Cast iron
o High strength steel o brass

Chrome plating applications
o Submerged electroplating: the type discussed earlier
o Rotary electroplating: same as the submerged but, the solution is poured over the plated area while an insulated brush rubs against the depositing area, the brush is connected to the positive terminal of the rectifier while the plated piece is connected to negative terminal best used for onsite applications
