This article introduce on research the results of materials properties of 67Ni18Cr5Si4B bimetalcarbon steel - Alloy existing in border area of two materials joined by plasma spraying method for the purpose of recovering worn cylindrical-shape machine parts. Investigating Material properties of thecoating layer by means of crystal structure analysis and SEM-EDX analysis method for the purpose of determining properties ofjoints between coating layer and primary material received from two types ofalloy powder spaying: directly on journal and on advance spayed lining layer. SEM-EDX analysis result allows determining chemical component, crystal structure of coating layer, intermediate area of coatinglayer and primary layer. That is scientific evidences proven for affection of hardness and durability of Plasma spraying coating layers serving as copper-alloy bush plain bearing and under working conditions of heavy loads and high abrasives. This is a part of experiment research result of research team of CTA-NARIME Center of National Research Institute of Mechanical Engineering, in which Ph.D. students is a key member.
