摘要

Due to a high strain hardening coefficient the nitrogen austenite shows promise for its use as the base (matrix) when producing new composite materials and coatings. The aim of the given paper is to obtain and study the structure, phase composition and properties of coatings of nitrogen-alloyed chromium-manganese cast iron as well as the fusion zone between the coating and substrate. We have determined the following characteristics: microhardness distribution, normal elasticity modulus, microstresses and macrostresses in the coating and fusion zone. It is shown that in the fu-sion zone, which provides conjugation of various crystal structures of the coating and substrate, the macrostress level is minimum and increases as the coating becomes thicker. Structural peculiarities of the fusion zone (no segregation of carbides and nitrides), low macrostresses and the distribution pattern of elastic properties in the coating deposited by electron beam deposition prove that this coating composition offers promise as a wear-resistant material.
