Supply of abrasion-resistant coatings for various Steel, Mine, Petrochemical, Cement and Micronized powder production industries in order to prevent the internal steel components being affected by abrasion. These coatings are composed of alumina ceramic (Al2O3 more than 90%) in various shapes and dimensions. Alumina Ceramic has not only high hardness, but also high mechanical resistance and corrosion resistant. Its thermal tolerance (up to 1600 Centigrade) makes it totally distinguished:
