With the continuous development of modern industrial technology, different production fields have put forward higher requirements for industrial processing methods. Traditional industrial production materials and processes have been difficult to meet the development needs of the current production field. Thermal spraying technology is currently a relatively advanced industrial processing technology. By using this technology, a coating with good wear resistance, corrosion resistance and high temperature oxidation resistance can be produced on the surface of mechanical parts, thereby protecting the working surface of the part and extending its working life. Ensure the safe operation of equipment.

Thermal spraying technology is a process technology in which the coating material is fed into a heat source to be heated and melted, and then sprayed on the surface of the substrate with a high-speed airflow to form a protective coating. The protective coating made by thermal spraying technology has the characteristics of corrosion resistance, wear resistance, high temperature resistance and heat insulation. In addition, this technology can also repair some parts whose dimensions have changed due to wear and corrosion. Today, thermal spraying technology has been widely used in machinery manufacturing, petrochemical, aviation equipment manufacturing and other fields.

Thermal spraying technology is one of the surface modification technologies, and it is also an important part of the development and application of surface engineering. The so-called thermal spraying technology is to use a heat source to heat and melt or soften the sprayed material, rely on the heat source itself or an external compressed airflow to atomize or push the droplets to form a sprayed particle beam, which is sprayed at a certain speed to the pre-heated The processing method of the surface of the workpiece to form a firm coating with certain special properties.
