After the laser cladding is completed, there will be a new coating on the surface of the workpiece. At this time, nitriding treatment can form a hard nitriding layer on the coating, further improving the hardness, wear resistance, corrosion resistance and fatigue resistance of the coating. Therefore, surface nitriding treatment is a supplementary process after laser cladding, used to further enhance the performance of the workpiece.
