Explanation

The process of thermo-chemical treatment in which sulfur is infiltrated into the surface of steel or cast iron workpiece. After sulphurizing, a vulcanization film with a thickness of less than tens of microns is formed on the surface of the workpiece, which can reduce the friction coefficient and improve the anti seizing performance. Gas sulphurizing (also known as ion sulphurizing) is widely used, including ion sulphurizing, ion sulfurizing, ion carbonitriding and other processes. sulphurizing is the final treatment on hardened or surface hardened parts. It is used for parts that need to bear severe friction and wear during use, such as high speed steel cutters, cams, rollers, etc.
