[en] Fabrication technique is developed for electromelted zirconium dioxide base powders with application of high frequency heating in a cold crucible. Cold crucible design and manufacture method are described. Test results are given on properties of powders obtained and coatings of these powders. X-ray analysis showes that main phases in ZrO₂-Al₂O₃-Y₂O₃ system powders are α-Al₂O₃ and ZrO₂ of tetragonal modification. It is revealed during plasma are coating of strainless steel substrate that powders possess good flowability and ensure homogeneous structure, high adhesion and low porosity of coatings
