Embodiment Construction
[0049] The material of the metal internal teeth in the embodiment of the present invention is a ferrous alloy metal, and its main chemical components include Fe, Cr, Ni, Mn, Mo, C, P, S, and Si. The iron and carbon contained therein can be combined with nitric acid, respectively. The principle of chemical reaction with hydrogen peroxide replaces the traditional metal cutting and forming method to quickly correct the shrinkage and deformation of the internal teeth of the metal workpiece after heat treatment, so that many problems caused by traditional metal cutting can be avoided. At the same time, in order to prevent the non-repaired part of the metal internal tooth workpiece from chemically reacting with nitric acid and hydrogen peroxide, the non-repaired part of the metal internal tooth workpiece is covered and protected to form a protective layer. The protective layer can be made of non-metallic materials (such as plastic, petrolatum, wax, etc.). If only the repaired part of th...
