Ion nitriding treatment plant

Ion nitriding treatment manufacturers include Qingdao Fengdong Heat Treatment Co., Ltd., Dezhou Dekai Heat Treatment Co., Ltd. and Dongguan Zhong Rui Metal Material Co., Ltd. ..

Ion nitriding forms R phase, and then hydrogen carbide system is added to form ε phase compound layer and diffusion layer. Nitriding treatment, also known as nitriding treatment, usually refers to a chemical heat treatment process in which the quenched and tempered parts are placed in a nitrogen-containing medium (such as ammonia gas) and kept at 500 ~ 540℃ for a proper time, so that new active nitrogen atoms generated by the decomposition of the medium penetrate into the surface of steel parts to obtain a white layer with a certain thickness and a diffusion layer with a certain depth to increase their hardness, wear resistance and corrosion resistance. Commonly used nitriding treatments include gas nitriding and ion nitriding. Not all steels are suitable for nitriding. When nitriding ordinary carbon steel, the surface hardness, wear resistance and fatigue strength of steel have not been greatly improved, and the expected effect can not be achieved. The main disadvantages of nitriding treatment are long treatment time, high production cost, thin nitriding layer and high brittleness.
