The supersonic spraying protective layer has a strong degree of bonding!

       

The development of modern industry has put forward higher requirements for the performance of various mechanical parts, and has also challenged the development of materials and their processing technologies. Considering the comprehensive performance and price ratio of the workpiece, a single material obviously cannot meet the requirements. In this case, various hard surface technology and spraying technology came into being and made great progress.

The principle of supersonic spraying is to use clean, high vapor pressure, high enthalpy propylene gas and high pressure oxygen, through a specially designed spray gun, so that both can generate a high-speed air flow of Mach 4-5. Guided by nitrogen, the coating material particles are accelerated by the injected gas stream to form a high kinetic energy particle beam. After the particles are in contact with the surface of the workpiece, mechanical inlay is achieved to form a protective layer. The airflow temperature of the supersonic spray system is moderate; the heat absorption of the particles during the acceleration process is small; the flying speed of the particles is high; the size of the protective layer is small, so the protective layer has the characteristics of high bonding strength, high density and good uniformity.
