ION PLATING( PHYSICAL VAPOUR DEPOSITION) PROCESS.
Ion plating is the latest technology in gold & decorative coatings.
Ion plating, also popularly known as PVD (physical vapour deposition) is done in a special chamber.
In Ion plating process, consumption of gold is very very less compared to conventional electroplating. TiN base coat provides very good adhesion & the plating losts for 2 to 3 years depending on the coating thickness & the usage. This is the biggest advantage of Ion plating.
Ion plating machines can be used for decorative coatings, TiN coating of toolings for prolonged life due to hardness of the coating.
