ALLOY POWDER FOR MATRIX COMPOSITION OF SINTERED ALLOY, SINTERED ALLOY CONTAINING ALLOY POWDER FOR MATRIX COMPOSITION AND MANUFACTURING METHOD OF SINTERED ALLOY

摘要

PROBLEM TO BE SOLVED: To provide an alloy powder for matrix composition capable of enhancing abrasion resistance of a sintered material constituting a valve seat with focusing on that Mo produces a hard article such as carbide, enhances abrasion resistance by dispersing the same, Ni and Mn are essential elements for stabilizing an austenite phase of a matrix together with C and elements having effects for enhancing heat resistance and improving abrasion resistance.SOLUTION: There is provided an alloy powder for matrix composition composing a matrix of a sintered alloy and containing, by mass%, Mn and Ni of total 12 to 28%, Mo of 10 to 30% and the balance with inevitable impurities and Fe.SELECTED DRAWING: None
