Plasma Ion Nitriding Services

We are offering Plasma Ion Nitriding in Bengaluru that is a process for surface treatment of metal parts to make them resistant to wear and fatigue.Parts to be treated are placed in a vacuum chamber and a high DC voltage (typically around 1000 volts) is established between the parts and the chamber wall. As nitrogen gas is introduced into the chamber, a glow discharge plasma (ionized gas) builds up around the parts. The reactive nitrogen atoms thus bombard the surface, forming a thin layer of hard metal nitrides.

Advantages of Plasma Nitriding are:-

Glow discharge that envelopes the entire surface achieves a consistent hardness and case depth. This is specially noticeable on complex geometries where gas nitriding case depths can be non-uniform.
Plasma nitriding (H2+N2) least affects the surface finish of the product. Gas nitriding, which uses ammonia (NH3) and phosphate for activa- tion , will roughen a ground or polished surface.
Higher surface hardness is achieved at lower processing temperatures (500 C). Thus distortion is almost zero and no changes in the properties at the core of the material
