FIELD: weapons and ammunition.
SUBSTANCE: proposed process comprises preliminary barrel etching and shot blasting. Then, first layer of nickel is applied by electrolytic process. Then, heat treatment is performed by high-temperature annealing at 600-610°C at heating and cooling rate of not over 15°C/min. Now, second layer is applied by slip process from slip composition, containing the following components in wt %: fine powder (Al, Cr, Ni, Fe) - 45-50%; chromic anhydride - 3%; surfactant - 0,2%, chromia-alumina-phosphate binder making the rest.
EFFECT: higher wear resistance, homogeneous improved chemical composition of gun barrel.
