Supersonic spraying, thermal spraying recommended

       The technical advantages of supersonic spraying: high thermal efficiency, it directly converts electrical energy into thermal energy to melt the wire, and the thermal energy utilization rate is as high as 70-80%. The production efficiency of supersonic spraying is high, which is reflected in the fact that there are many metal wires sprayed per unit time. Supersonic spraying is easy to operate.

  The bonding strength of the supersonic spray coating can reach 60MPa, which is close to the quality of the plasma. In addition, the porosity of the HVOF coating is low. At the same time, the porosity of the surface of the supersonic spraying coating is generally lower than 1%, which improves the wear resistance and corrosion resistance of the coating; because of the unique advantages of supersonic spraying The wide application in the production field shows that the supersonic spraying technology has produced great economic and social benefits for us.

Thermal spraying technology is a method of using a heat source to heat the sprayed material to a melted or semi-melted state, and spraying and depositing it on the pretreated substrate surface at a certain speed to form a coating. Thermal spraying is powered by fuel gas or electric arc etc. Thermal spraying technology creates a special working surface on the surface of ordinary materials, so that it can achieve a series of functions such as anticorrosion, wear resistance, friction reduction, etc., so that it can achieve the purpose of saving materials and energy. We put special work The surface is called coating, and the working method of making coating is called thermal spraying, in which the thickness of thermal spraying coating can be from 0.01 to several millimeters. Thermal spraying is a surface strengthening technology, and thermal spraying technology is one of the important components of surface process technology. The base material of thermal spraying is not limited and can be metal or non-metal.
