Abstract: An electric arc sprayer has been improved, which makes it possible to improve the quality of composite coatings by increasing the particle velocity in a high-temperature heterophase jet and reducing its opening angle, which leads to an increase in the CMM during spraying from 0.63 to 0.74. The optimal temperature-time parameters of pre-recrystallization heat treatment are established, which provide a further increase in the hardness of coatings due to the grinding of subgrains to the nanoscale size inclusive. The possibility of thermal stabilization of the polygonization substructure of electric are coatings obtained by spraying 12×18n10t wire by their additional plastic deformation is shown.
