ABSTRACT:
Disclosed are an Fe-based alloy powder adapted for sintering, an Fe-based sintered alloy, and a process for producing the Fe-based sintered alloy. The Fe-based alloy powder or the matrix of the Fe-based sintered alloy consists, percent by weight, essentially of 2.0 to 15% Co, 2.0 to 10% Mo, and the balance of Fe and inevitable impurities. The Fe-based alloy powder exhibits superb compressibility and corrosion resistance, and accordingly the Fe-based sintered alloy made therefrom exhibits excellent wear resistance, corrosion resistance and oxidation resistance. The Fe-based sintered alloy is further improved in the excellent properties by dispersing novel Ni-based alloy hard particles in the matrix.
