description: The purpose of the work is to study the operating modes of the PN-31 air-arc plasma torch to assess the qualities of the coatings created and the possibility of their use for contact assemblies of electrical devices. To achieve this goal, an analysis of modern publications on the subject of plasma coating was carried out, a mathematical model of the PN-31 plasma torch was developed in the COMSOL Multiphysics program, in which the calculation of the operations modes of device with only internal and internal arc transferred was carried out. As a result, graphs of temperature, velocity and pressure of the plasma-forming gas were obtained and compared. The power supply circuit of the transferred arc of the PN-31 plasma torch was also assembled and deposition experiments were carried out, the purpose of which was to find the optimal parameters of the circuit entangling the transferred arc to obtain the best quality coatings.
