At the alloy powder for abrasion resistance hard phase formation and production mannered null mass ratio of the abrasion resistance sintering

摘要

PROBLEM TO BE SOLVED: To provide powder which is excellent in forming a hard phase dispersed in a sintered alloy for a wear-resistant member, and a production method for a sintered alloy in which the hard phase formed by the powder is dispersed. ;SOLUTION: The alloy powder for forming a wear-resistant hard phase has a composition containing, by mass, 1.0 to 12% Si, 20 to 50% Mo and 0.5 to 5.0% Mn, and the balance at least one or more kinds selected from Fe, Ni and Co with inevitable impurities. This alloy is added to master alloy powder using iron powder or low alloy steel powder, and they are mixed. This powdery mixture is compacted, and is thereafter sintered in the temperature range of 1,000 to 1,250°C to obtain the wear-resistant sintered alloy.;COPYRIGHT: (C)2003,JPO
