<p>A metal sintered body; the subject of this invention is produced by the following example processes in order to offer a metal sintered body, which has a high degree of hardness and a superior wear resistance, and, in order to offer the uncomplicated production method. Process 1A:producing a green body, which is manufactured from a metal powder and a binding material, by the metal injection molding (MIM) method. Process 2A: conducting the de-binding treatment to the green body. Process 3A: sintering the de-bound body and obtain the metal sintered body. The metal powder for the production is a self-fluxing alloy, such as a nickel based self-fluxing alloy. The surface Vickers hardness Hv of this product is more than 500. <IMAGE></p> |
