Abstract

Application of the method of acoustic emission to study the processes of structural adaptability in friction under conditions of slip for the tribosystem of steel 30HGSA and duraluminium D16, on the surface of which the method of electroscope alloying is applied an alloy BK8 followed by surface processing by superficial plastic deformation. The formation of wear-resistant secondary structures has been established by increasing the intensity of heat emission in the frictional contact, which leads to an increase in the mechano-chemical activation of the surface layers of the metal. The modification of dyuraluminium D16 by the electrospray coating ВК8 provides a reduction of the average power of acoustic emission by 2 times during the wear-in stage by reducing the stress-strain state of the surface layers and reducing the ability of the material ВК8 to absorb mechanical energy during deformation. The correlation dependence of the total weight wear of friction pairs and the average power of acoustic emission is established
