Laser cladding refers to the different ways to add materials on the surface of the substrate to be cladding placed on the selected coating material by laser irradiation and the substrate surface of a thin layer of simultaneous melting, and rapid solidification to form a low dilution, and the substrate into a metallurgical combination of surface coatings, to improve the grass-roots surface of the abrasion-resistant, corrosion-resistant, heat-resistant, oxidation-resistant, and electrical characteristics of the process, so as to achieve the purpose of the surface modification or restoration, which meets the specific performance requirements of the material surface and save a large number of precious elements. It not only meets the requirements of specific properties of material surface, but also saves a lot of precious elements.

Laser cladding wear resistance test
Laser cladding is the process of fusing or semi-molten powder on top of a molten bath by changing the interaction between the laser and the powder, and feeding a stream of molten or semi-molten liquid into the bath to achieve improved cladding efficiency and surface quality, and to form a metallurgically bonded surface coating. The surface of the finished coating can be quickly laser scanned to improve the surface quality again. High-speed laser cladding process can improve the wear resistance, corrosion resistance, heat resistance and other properties of the surface of the workpiece, especially the improvement of wear resistance is one of the more important indicators. For the fusion cladding wear resistance test there are mainly the following methods: 1 weightlessness method, that is, friction wear test wear before and after the weight difference to measure the wear resistance, the smaller the weight difference is the better the wear resistance, and vice versa was established. Measurement requires the use of high-precision weighing scales. In the test, the coefficient of friction is measured by reading the friction torque directly from the testing machine and recording the movement trajectory with a recorder, and then calculating the coefficient of friction using the measured friction torque.2 Dimensional Change Measurement Measurement Measurement of the amount of change in size of the wear area by using a spiral micrometer or a micrometer caliper, e.g., if the workpiece is a cylinder, measure the amount of change in the diameter of the wear area.3 Surface Topography Measurement Measurement Method Using a Palpation Type Surface Topography Measurement Method Surface Profile Measurement Method utilizes a tactile surface profilometer (profilometer or step meter) to measure the change in surface roughness before and after wear.
