Abstract
The paper presents the study of Ni-based coatings deposited by plasma detonation onto a steel substrate after direct current low-energy electron beam irradiation and proposes explicit parameters of the electron beam for modication of coatings by irradiation.The choice of irradiation modes is based on the calculation of the temperature prole in the NiFe two-layer absorbents using numerical simulation methods.It was found that the exposure of coatings to irradiation according to the recommended modes leads to the evolution of the structural--phase state of coatings and substantial improvement of performance properties of modied surfaces.The wear resistance of modied surfaces increases 3 times, the microhardness increases on the average 25%.
