Estimation of Wear Resistance for Multilayer Coatings Obtained by Nitrogenchroming

This article deals with improving the wear resistance of multilayer coatings as a fundamental problem in metal surface treatment, strengthening elements cutting tools, and ensuring reliability machine parts. It aims to evaluate depth for by mass loss distribution layers. The article’s primary purpose is develop mathematical method assessing value steel-based coatings. study material coating applied steel DIN C80W1. research was performed using up-to-date laboratory equipment. Nitrogenchroming has been realized under overpressure two successive stages: nitriding 36 h at temperature 540 °C chromizing during 4 1050 °C. complex analysis included several options: X-ray phase analysis, local micro-X-ray spectral durometric determination resistance. These analyses showed that after nitrogenchroming, three-layer protective from Cr23C6, Cr7C3, Cr2N formed on surface. Spectral indicated maximum amount chromium 92.2% first layer Cr23C6. carbon 8.9% characterizes Cr7C3. Nitrogen concentrated mainly layer, its 9.4%. Additionally, it determined minimum typical C80W1 nitrogenchroming. weight samples 25 mg obtained. differs 3.6% results evaluated analytically developed model metallization As result, impact loading mode intensity established. time increases, friction coefficient coated decreases. Among studied samples, plates have lowest linear dependence losses wearing obtained carbide nitride Finally, an increase leads steels achieved scientific are applicable developing methods chemical-thermal coatings, highly loaded parts tools.
