Ion nitriding is an effective surface strengthening process, for precision parts, it can significantly improve the surface hardness and wear resistance of the parts, thus improving the durability and service life of the parts. Ion nitriding is an ionic chemical heat treatment process that uses the glow discharge phenomenon to bombard the surface of parts with nitrogen ions generated by ionisation of nitrogen-containing gases, and forms a nitriding layer on the surface of the parts by heating and nitriding. This process is applicable to a variety of materials, including cast iron, carbon steel, alloy steel, stainless steel and titanium alloys, etc., can significantly improve the hardness of the surface of the material, enhance wear resistance, fatigue strength, corrosion resistance and burn resistance.

In the manufacture of precision parts, ion nitriding technology is particularly important. Through ion nitriding treatment, the surface hardness and wear resistance of precision parts can be significantly improved, which is essential for maintaining the accuracy and performance of precision parts. For example, the application of ion nitriding moulds is to extend the service life of moulds by improving surface hardness and wear resistance, as well as improving fatigue strength and corrosion resistance.
