In the industrial field, coating powder material is a kind of surface engineering application material. It is coated on the surface of the substrate to resist wear, corrosion, high temperature, oxidation and aging, and meet special effects or functions such as light, electricity and magnetism. As the manufacturing of some products becomes more and more sophisticated and the service conditions become more and more harsh, higher requirements are also placed on surface coating materials. People have found that when the characteristic scale of the material is reduced to the nanoscale, the properties of the material will be significantly different from those in the macroscopic world due to small size effects, quantum effects, interfaces or surface effects. This has also prompted scientists to think of integrating nanotechnology with surface engineering.
