Vacuum Plasma Nitriding

Vacuum plasma nitriding (VPN) is a kind of surface treatment technology that excites gases such as nitrogen and hydrogen into plasma through high-frequency electric current or microwave, and plasma generates nitride on the surface of parts and penetrates into the metal matrix to form a layer of wear-resistant nitrid layer, which is mainly used to enhance the hardness, wear resistance, corrosion resistance and fatigue strength of the metal surface. WELLTECH currently has vacuum plasma nitriding of nickel-based high-temperature alloy Inconel 718, with a surface hardness of parts above 60HRC and an effective thickness of the nitrided layer above 10 μm.
