ABSTRACT:
A wear-, corrosion-, heat-, and abrasion-resistant sintered body is prepared from a metallic powder mixture of from about 95 to 99.5% of a base alloy powder and about 0.5 to 5% of an additive alloy powder, wherein the additive alloy has a melting point which is lower than the melting point of the base alloy such that when pressed and sintered at a temperature above the melting point of the additive alloy and below the melting point of the base alloy a sintered body is produced having a density of at least 95% of the theoretical density.
