Characteristics of thermal spraying technology

From the analysis of the principle and process of thermal spraying technology, the thermal spraying technology has the following characteristics.

1.Due to the wide temperature range of the heat source, the coating materials that can be sprayed include almost all solid engineering materials, such as metals, alloys, ceramics, cermets, plastics and their composites, which can endow the substrate with the surface of various functions (such as wear resistance, corrosion resistance, high temperature resistance, oxidation resistance, insulation, heat insulation, biocompatibility, infrared absorption, etc.).

2.During the spraying process, the heating degree of the substrate surface is small and controllable, so it can be sprayed on various materials (such as metal, ceramic, glass, cloth, paper, plastic, etc.), and has little impact on the microstructure and properties of the substrate, and the workpiece deformation is small.

3.The equipment is simple and easy to operate. It can spray large-scale components in a large area or at designated parts.It can be sprayed indoors in the factory or constructed outdoors on site.

4.Spraying operation has fewer procedures, shorter construction time, high efficiency and economy.
