- Summary:
- This paper is devoted to the methods of increasing wear resistance, corrosion resistance, and service life of parts and assemblies of vehicles during their strengthening and renovation by the use of combined electric arc spraying (EAS) coatings. High density, adhesion, and microhardness of EAS coatings are provided by activation of the spraying process and subsequent nitriding of the sprayed coatings. This study is about the influence of technological parameters of the spraying processcomposition, diameter and feed rate of sprayed wires, arc power, spray gas flow rate, spraying distance, speed of spraying spot movement, dispersion of spraying, et ceteraon the qualitative characteristics of EAS coatings. The possibility of using pulsed ion nitriding (PIN) to improve the operational characteristics of EAS coatings made of wire materials is considered. Also the control of the recovered surfaces in order to increase the service life of parts, assemblies, and assemblies of transport means is due to the choice of design parameters and characteristics of equipment for EAS. The work shows that the correct selection of equipment and its technological parameters will increase the speed and temperature of the jet of the transporting gas and particles, reduce the diameter of the droplets, increase the density, and reduce the oxidizability of the coatings
