Furthermore, the method of the present invention is a method for manufacturing an axle housing having a part of a cast steel body that rubs violently against other members such as a leaf spring, in which high hardness alloy grains are added to the surface of a mold forming the part. Spread it and
After that, the material for the main body is cast into the mold, and the high-hardness alloy is melted by the high heat of the material and impregnated into the part.

The figure shows an enlarged view of the main part of the axle housing 11 of the present invention, that is, the part 11L+ of the cast steel main body that rubs violently against other members 2 (Fig. 1) such as leaf springs. The surface of the portion 11b is impregnated with a high hardness alloy M. As the high hardness alloy M, iron-molybdenum alloy (Fe Mo), iron-based OA gold alloy Fe

含浸される。High-hardness alloy grains MG are scattered on the surface of the mold 4b, and then the material for the main body 11a is cast into the mold in the usual manner. Then, the high hardness alloy particles MG are melted by the high heat of the material and impregnated into the part 11b of the axle housing 11, which is the product.

って維持される。The present invention is configured as described above, and its operation will be explained below. Since the casting of the axle housing 11 is completed with the high-friction portion 11b impregnated with the high-hardness alloy M, there is no need to perform welding to reinforce the portion after casting9, which saves man-hours. Furthermore, the friction portion 111) of the axle housing 11 impregnated with a high-hardness alloy will not wear out even if it rubs against another member 2, such as a leaf spring, because the high-hardness alloy MO impregnated on the surface has high wear resistance. Moreover, even if it wears out to some extent, a new high-hardness alloy M appears on the surface, so high hardness is maintained for a long period of time.
