Metal Finishing

An electrolytic surface treatment

The electrolytic surface coating is, in principle, a simple electro-chemical process, where a metal is deposited cathodically on components in an electrically conducting solution (electrolyte) by the use of direct current. Thus it is also called electro-plating where a power source serves as an electron pump.

The metal to be deposited can either be dissolved from the anode (e.g. Copper) or is added into the electrolyte as a salt (e.g. Hard Chrome). Every coating is merely as good as its adhesive strength. Only an atomic, metallic binding to the base material can be called “adhesive compound” and is dependent on an optimal pretreatment.

Adhesive coatings produced by the MTV NT GmbH cannot be separated from the substrate without mechanical destruction of the base material.
