HVOF Thermal Spary Coating
Hello, this is Microcontrols, a company specializing in warrior coatings. HVOF is a spraying technique characterized by high-speed spraying using oxygen as fuel. The temperature of the flame is around 3,000 degrees, and the scattering speed of the particles melted in the ultra-high-speed jet of about 2,100 m/sec is about 800 ~ 900 m/sec. It is sprayed at the fastest speed among thermal spraying to be called super-high-speed thermal spraying, so it has the advantages of high adhesive strength and low porosity compared to other thermal spray coatings, and the time that the molten thermal spray material is exposed to the air is relatively short, so changes such as oxidation can be minimized. It is mainly suitable for spraying carbide-based powders with high wear resistance such as tungsten carbide or chromium carbide with high hardness, or materials with strong acid resistance and corrosion resistance such as Hastelloy or Inconel. It has the advant...
