Supersonic spray coating performance parameters

       As one of the branches of surface engineering technology, supersonic spraying technology is a new surface strengthening and surface protection technology. In the past three decades, it has developed rapidly at home and abroad. Its main feature is that it can spray almost most solid-state engineering materials such as various metals and alloys, ceramics and cermets, plastics, and non-metallic minerals. It is made into various functional coatings such as wear resistance, friction reduction, corrosion resistance, high temperature resistance, oxidation resistance, heat insulation, insulation, electrical conductivity, radiation protection, anti-interference, and energy conversion. Supersonic spraying technology is a low-input, high-output project. It can be protected by spraying and surface strengthening or repaired and used, and its life can be doubled or even dozens of times longer. Supersonic spraying technology has typical applications in various types of equipment in modern machinery manufacturing, electric power industry, metallurgical industry, automobile industry, aviation industry, petrochemical industry, papermaking and other industries. Coating performance parameters Coating thickness 0.05 ~ 2mm Coating hardness HV900 ~ 1300 Coating bonding strength: ≥ 90MPa Porosity: ≤ 1% Surface roughness: mirror surface after polishing (within Ra0.2) Acid, alkali, salt, Corrosion and temperature resistance such as hydrogen sulfide: up to 1200 ℃
