SINTERED ALLOY OF STAINLESS STEEL HAVING SUPERIOR SURFACE COMPACTNESS, SURFACE HARDNESS AND CORROSION RESISTANCE, AND MANUFACTURING METHOD THEREFOR

摘要

PROBLEM TO BE SOLVED: To provide a sintered alloy of stainless steel having superior surface compactness, surface hardness and corrosion resistance, and to provide a manufacturing method therefor.;SOLUTION: The sintered alloy of the stainless steel having the superior surface compactness, surface hardness and corrosion resistance has a surface layer part thereon with a thickness in a range of 1 μm to 2 mm, which contains a higher average concentration of P than that of the inner part of the sintered alloy by 0.01 to 1 mass%, and which contains 0.01 to 1 mass% K and/or Na by average concentration.;COPYRIGHT: (C)2005,JPO&NCIPI
