ABSTRACT:
The invention provides a novel method for firmly bonding a porous body, e a sintered body prepared by the powder metallurgical techniques with a metal powder, and a fusion-made body, e.g. an iron casting body, hitherto undertaken by the method of pressure welding or diffusion bonding. The inventive method utilizes the principle of infiltration and an infiltrater material is placed at the contacting portion between the porous body and the fusion-made body and heated at a temperature to exceed the melting point of the infiltrater material in vacuum so that the molten infiltrater material is infiltrated into the porous body leading to strong bonding upon solidification to have the porous body and the fusion-made body integrally bonded together.
