The surface layer and the core are studied by diffractometric analysis and scanning electron microscopy. The microhardness and the tribological characteristics of the alloy are determined. The effect of the temperature of nitrocarburizing on the wear resistance, surface roughness and friction coefficient of the alloy is considered. © 2017 Springer Science + Business Media New York.Springer New York LLC2017Articlehttps://rdlopen.rawdatalibrary.net/r/ebyu/14582https://doi.org/10.1007/s11041-017-0089-x0026-0673enMetal Science and Heat Treatmentinfo:eu-repo/semantics/openAccessinfo:eu-repo/semantics/articlehttps://ebyu-rdlopen.rawdatalibrary.net/tr/items/ebyu/14582
