Abstract

1. The process of depositing coatings by pyrolysis of metalloorganic chromium compounds is distinguished by high productivity. 2. Depending on the regime of deposition, coatings with different structure and phase composition may be obtained: practically amorphous homogeneous deposits in the kinetic region, horizontally laminated ones in the intermediate region, columnar and dendritic coatings based on chromium and its carbides in the diffusion region. 3. Maximum wear resistance is attained in coatings with horizontally laminated structure. There we also find maximum adhesion of the coatings to various structural materials. 4. Horizontally laminated coatings are practically without pores and have high corrosion resistance in weakly acid chlorine containing media, this resistance being substantially higher than the resistance of steels type 08Kh18N10T.
