What is the role of carburizing powder metallurgy products

Carburizing in powder metallurgy is to improve the surface hardness and wear resistance of the product. Carburizing is often achieved using other solid or liquid forms. We use hydrogen for carburizing treatment, which to a certain extent penetrates the carburizing into the product. Inside the body of the product, a carburized layer is formed on the surface. Carburization is generally controlled at a carburization value of 0.2-2.5mm. Because powder metallurgy is a porous structure, if the carburization is too high, it will easily produce carbonization, brittleness, and failure to The surface hardness required for carburizing must be high, and the internal toughness must be good for carburizing. Therefore, when performing the carburizing process in powder metallurgy, special care must be taken to control the carbon content and depth.
