The appliance of electropulse impacton the spraying distances to enhance the properties of plasma sprayed coatingsis discussed. The aim of research is to set the impact of high-voltage electrical pulses on the process of applying the plasma coatings and their mechanical properties.The structure and mechanical propertiessuch ashardness, bond strength, wear resistance of bronze plasma sprayed coating obtained using the electropulse impact are studied experimentally. Set the effect of The enhancement of mechanical properties of coatings obtained by grinding their structure and improving the speed of sprayed particles are set. The research results can be applied in thetechnology of repair and restoration of machines elements and mechanisms.The fixed effect allows us solving the problem of providing the high quality plasma sprayed coatings. = Исследовано влияние наложения электрических импульсов при плазменном напылении на механические свойства покрытий.
