What is chrome oxide spray? What is the use?

First, chrome oxide spraying, also known as: chromium oxide
Second, the chemical formula of chromium oxide spraying: Cr2O3
Third, the content of chromium oxide spraying components: ≥ 99.5% (ordinary) or ≥ 99.9% (high purity)
Fourth, the material properties of chromium oxide spraying: chrome oxide green, also known as chromium oxide, chromium oxide, is a hexagonal system, green powder. Its molecular weight is 151.99, the density is 5.21g/cm3; Mohs hardness is 8.5-9, close to corundum (Al2O3), and exceeds quartz (SiO2) and topaz (Al2(SiO4)(OH)2); the refractive index is 2.5 ( Good hiding rate), specific heat capacity (20 ° C) is 0.17J / (g · K); insoluble in water, acid and organic solvents, extremely stable to light, atmospheric and corrosive gases (H2S, SO2, etc.), excellent weather resistance.
Chromium oxide green is stable to heat, has a melting point of 2265 ° C and a boiling point of 3000 ° C. It is a high quality refractory material. The chrome oxide green commonly found in the market is bright green to dark green, with metallic luster; it has the characteristics of magnetism, strong hiding power, high temperature resistance, sun resistance, insoluble in water, and insoluble in acid. It is relatively stable in the atmosphere. The general concentration of acid and alkali and sulfur dioxide gas have no effect on it, and has excellent outstanding pigment quality and fastness.
Fifth, the way of chromium oxide spraying: high-energy atmospheric plasma spraying, hardness HV900-1100, porosity is less than 3%
Sixth, the application range of chrome oxide spraying: suitable for ceramic anilox roller, plunger, various sealing rings, bushings, pump impeller, cylinder liner of diesel engine, fan blades, etc.
