Rise of efficiency of application of railway transport requires new technologies and materials for increase of their life, first of all of the critical parts of rolling stock. In this aspect one of the most perspective technologies is a supersonic electric arc spraying or supersonic air-gas electric arc metallizing. It allows eliminating the main disadvantages of a traditional electric arc spraying related with low quality of coating, namely, increased burning out of the alloying elements of wire metal being sprayed due to air jet effect, low adhesion strength of the coating with the base material. 12 Ref., 2 Tables, 8 Figures.
