Abstract (en)
[origin: EP3054024A1] A metal powder for powder metallurgy includes particles, which contain Fe as a principal component, Cr in a proportion of 0.2 mass% or more and 35 mass% or less, Si in a proportion of 0.2 mass% or more and 3 mass% or less, and C in a proportion of 0.005 mass% or more and 2 mass% or less, and in which when two elements selected from the group consisting of Ti, V, Y, Zr, Nb, Hf, and Ta are defined as a first element and a second element, the first element is contained in a proportion of 0.01 mass% or more and 0.5 mass% or less and the second element is contained in a proportion of 0.01 mass% or more and 0.5 mass% or less, wherein the content of Cr on the surface of each particle (Cr(0)) is 0.2 at% or more and 15 at% or less and is 70% or more and 170% or less the content of Cr at a depth of 60 nm from the surface of each particle (Cr(60)).
