FIELD: metallurgy.
SUBSTANCE: coating in the form of electrolytically produced nanocomposite is applied onto a metal rod, including a metal matrix with nanosize particles of activating flux evenly distributed in it, containing fluoric compounds, and nanosize particles of carbide or a mixture of carbides. The coating has the following ratio of volumes of the matrix and nanosize particles, %: metal matrix 30-92, nanosize particles of activating flux 3-5, nanosize particles of carbide 5-65. Carbide or a mixture of carbides are selected from the following group: tungsten carbide, chrome carbide, molybdenum carbide, vanadium carbide, titanium carbide, niobium carbide, hafnium carbide, tantalum carbide, boron carbide, zirconium carbide.
EFFECT: wire has good welding-technological properties, provides for atomised transition of electrode metal and makes it possible to increase hardness of a wear resistant layer aimed at surface of parts working under intensive impact-abrasive wear.
