Fundamentals of microplasma spraying technology for restoration of local damages in enamel coatings of tank equipment were developed. A double-layer repair coating consisting of a layer of zirconium oxide and tantalum sublayer was proposed. The optimum parameters of microplasma spaying mode were determined in order to obtain a layer of zirconium oxide with dense microstructure (porosity 1.2–1.9 %). It is shown that application of tantalum-based sublayer increases adhesion strength of zirconium oxide coating by 25 % (up to 8.14±2.16 MPa). Evaluation of coating through porosity was carried out. A method was proposed for increase of coating uniformity using epoxy-resin treatment. The technology was approved under real production conditions at CJSC «Kharkovreakhim». 15 Ref., 1 Table, 6 Figures.
