Abstract
A sintered alloy having superior heat resistance and superior wear resistance and also having corrosion resistance against salt damage that may occur in cold-weather regions, and a production method therefor, are provided. The sintered alloy consists of, by mass %, 32.4 to 48.4% of Cr, 2.9 to 10.0% of Mo, 0.9 to 2.9% of Si, 0.3 to 1.8% of P, 0.7 to 3.9% of C, and the balance of Fe and inevitable impurities, and it has a density ratio of not less than 90% and includes carbides that are dispersed in a matrix of a metallic structure thereof.
