Plasma Nitriding

Technical introduction

Under the action of a strong electric field in the plasma region, positive ions of nitrogen and hydrogen bombard the surface of the workpiece at high speed. The high kinetic energy of the ions is converted into heat energy, which heats the surface of the workpiece to the desired temperature. Due to the bombardment of ions, the surface of the workpiece is sputtered, which is purified; at the same time, due to adsorption and diffusion, nitrogen then penetrates into the surface of the workpiece to form a nitriding layer.

Compared with gas nitriding, it has the advantages of fast nitriding speed, easy control of nitriding layer structure, small brittleness, no environmental pollution, energy saving, and small deformation.
