Patent ID: 6852143

Claim:
A turbo component for a turbocharger having overall composition, in ratio by mass, of Cr: 23.8 to 44.3%, Mo: 1.0 to 3.0%, Si: 1.0 to 3.0%, P: 0.1 to 1.0%, C: 1.0 to 3.0%, and the balance of Fe and inevitable impurities and Cr carbide is dispersed in the matrix at a density ratio of 95% or more, wherein the turbo component is obtained by steps comprising: using a mixed powder having 1.0 to 3.3 mass % of Fe—P powder including P: 10 to 30 mass %, and 0.5 to 1.5 mass % of graphite powder, added to Fe alloy powder comprising, in ratio by mass, Cr: 25 to 45%, Mo: 1 to 3%, Si: 1 to 3%, C: 0.5 to 1.5%, and the balance of Fe and inevitable impurities; forming the mixed powder; and sintering.
