FIELD: weapons and ammunition.SUBSTANCE: when manufacturing an item, formation of a coating on an inner surface of a barrel, smooth or rifled barrel, is carried out by means of mechanical pressure from a tool in the amount of at least 2.5 N/mm. The coating material is represented by finely dispersed powders of natural mineral materials with energy density of at least 80 kJ/cmor their mixtures with a process medium. As a result, the coating with thickness of at least 50 mcm is produced. In process of operation the coating of the inner surface of the barrel is recovered periodically via a number of shots determined for each type of firearms by means of a tool developing pressure of at least 2.5 N/mmand by using powders of natural mineral materials or their mixtures with a process medium at the ratio of 1:1.EFFECT: on an inner surface of a firearms barrel a corrosion-resistant coating is produced, which recovers the inner surface of the barrel and increases close pattern of shooting.2 cl, 2 ex |
