NITRATION MTK TECHNICAL COATING

NITRATION Nitriding is a surface treatment process. As a result of the diffusion of nitrogen to the steel surface, a hard layer with high wear resistance is formed on the surface of the material. Every material has a nitration ability. Nitriding increases corrosion resistance and fatigue strength in some steels. WHY NITRATION Deformation is less during the process. The friction resistance is high. Nitriding is applied to all steels. All steels have the ability to be hardened. Since it penetrates into the steel, flaking, etc., does not occur, such as chrome plating. BENEFITS Nitriding provides high resistance to abrasion, friction, flaking and wrapping, thanks to its high surface hardness, especially in parts subject to overload. Especially by improving the surface compression stresses, the fatigue strength is increased. APPLICATION AND MATERIALS General applications: gears, crankshafts, camshafts, cam followers, valve parts, springs, extrusion screws, die casting tooling, forging dies, aluminum extrusion dies, injectors and plastic injection moulds. Nitriding is more effective when applied to steel grades containing nitride-forming elements such as chromium, molybdenum, vanadium, and aluminum. The process can also be applied to tool steels such as hot work, cold work steels and die steels. Since nitration takes place at low temperatures, spring steels can also be hardened with this method, thus extending the fatigue life of springs used in the automotive industry. For best results, the material should be hardened and tempered prior to nitration.
