Abstract
A sintered alloy having superb wear resistance consisting, percent by weight of, as a whole, Ni in the amount of 1.35 to 19.61%, Cr in the amount of 0.9 to 11.05%, Mo in the amount of 1.44 to 9.09%, Co in the amount of 3.6 to 20.05%, V in the amount of 0.018 to 0.26%, Si in the amount of 0.1 to 0.75%, C in the amount of 0.35 to 1.5%, and the balance of Fe, and the sintered alloy exhibiting a metallographic structure in which the following hard phases are dispersed in a mixed structure of martensite, sorbite, and austenite: a first hard phase comprising, a hard phase as a core mainly consisting of Mo suicide, and a diffused phase including diffused Co surrounding the hard phase; and a second hard phase comprising, a hard phase as a core consisting of Cr carbide, and a mixed phase of ferrite and austenite surrounding the hard phase.
