I ron-based alloys doped with copper can be attributed to anti-friction materials [1–5]. A decrease in the coefficient of friction for lowcarbon steel [1] and cast iron [2] was noted when copper is added. The decrease in the friction coefficient depend on the concentration of coppercontaining particles ranging in size from several nanometers to tens of micrometers. Such particles can be formed, both during prolonged isothermal annealing of hardened steel [6–9] and during crystallization of cast iron-carbon alloys [1–4]. Doping with copper leads to changes in the structure and mechanical properties of the hypereutectoid steel [10]. Adding of 3 wt.% Cu to steel is accompanied by an increase in the microhardness of perlite from 380 to 430 HV. Moreover, the Brinell hardness increases from 340 to 390 HB. For copper containing alloys, the dispersion of the ferritic cement mixture is inherent. An additional factor contributing to the growth of the perlite hardness is the isolation in the ferrite gaps of nano-dimensional particles of the ε-phase. In sliding friction with lubrication, the wear resistance of hypereutectoid steel containing 8.97% copper is by ~23% higher than that of antifriction cast iron АЧС-1. During laser cladding alloying elements are introduced into a ПОЛУЧЕНИЕ ИЗНОСОСТОЙКИХ И ЗАДИРОСТОЙКИХ ПОКРЫТИЙ ПРИ ЛАЗЕРНОЙ НАПЛАВКЕ ПОРОШКОМ НА ОСНОВЕ ЖЕЛЕЗА С ДОБАВКАМИ НАНОПОРОШКА ОКСИДА МЕДИ
