[en] Production processes and properties of oxide (Al₂O₃, ZrO₂) and metal-oxide (Mo-Al₂O₃, Mo-ZrO₂, W-Al₂O₃, W-ZrO₂) coatings on molybdenum substrates and uranium dioxide fuel particles were investigated. It is shown that the main factors that have an effect on the deposition rate, density, microstructure and other properties of coatings are the deposition temperature, the ratio of H₂ and CO₂ flow rates, the total reactor pressure and the ratio of partial pressures of corresponding metal chlorides during formation of metal-oxide coatings
