Study of Effect of Annealing on Morphology and Elemental Composition of Pyrolytic Chromium-Carbide Coatings on Steel Lattice

Results of the elemental composition detection, of the X-ray diffraction analysis, and of metallographic research on pyrolytic chromium-carbide coatings (PCCC) are presented in the article. Coatings on a steel substrate are obtained by deposition from a gas phase using "BARHOS"s (a chrome-containing metalorganic liquid) and by furthert annealing at 700–1000°C on air and in a vacuum. The research showed good prospects for PCCC to be used for modification of the steel products surface that are operated at temperatures up to 1000°C
