Gas Nitrocarburizing Treatment

Gas Nitrocarburizing Treatment Technology

Gas nitrocarburizing is one type of nitrocarburizing method developed to achieve at least the same quality and properties as conventional salt bath nitrocarburizing but without the problems of quality and environmental burden.
Generally, temperature is set around 570 degrees Celsius for gas nitrocarburizing. During the process, mixed gas with the main ingredient of ammonia gas is added which causes carbides and nitrides to form a compound layer on the surface of the fabricating material, resulting in a diffusion layer underneath. This formative nitride layer markedly improves mechanical properties, including abrasion resistance, corrosion resistance and fatigue endurance, of the steel part.
Gas carburizing is considered an eco-friendly treatment method as it is non-polluting and achieves effective quality properties in a short time. The applications for this surface hardening method will likely continue to increase going forward because it can accommodate the trend toward lighter more compact parts from the popularization of electric vehicles and it is considered a more eco-friendly treatment method.
