Manufacturing method of wear-resistant barrel

A manufacturing method of a wear-resistant barrel comprises steps as follows: 1, a barrel blank is selected and is machined to form a barrel; 2, a formula of nickel-based alloy powder is formulated; 3, the nickel-based powder is mixed to form a mixture according to the formula in the step 2; 4, a pull wire with the set strength is selected, and corundum is uniformly bonded to the pull wire; 5, the mixture at the temperature ranging from 70 DEG C to 80 DEG C is placed in an inner cavity of the barrel with the temperature controlled to range from70 DEG C to 80 DEG C, is spread on the inner wall of the barrel and is uniformly cut by the aid of a pull wire head. The method has the advantages as follows: the manufacturing technology is simple and stable, an inner wear-resistant layer manufactured on the inner wall of the barrel is high in strength and good in wear-resistant performance, more importantly, the wear-resistant layer of the barrel manufactured with the method has the uniform thickness, and with the method, the thickness of an inner wear-resistant layer on an inner wall of a relatively long barrel or an ultra-long barrel can completely meet the requirements for uniformity and consistency; and the technical problem that wear-resistant layers of long barrels cannot be uniform and consistent so far is solved.
