Abstract
Official abstract text for this publication.
Provided is a copper-base alloy with excellent wear resistance. The wear-resistant copper-base alloy includes, by mass %: 5.0 to 30.0% nickel; 0.5 to 5.0% silicon; 3.0 to 20.0% iron; less than 1.0% chromium; less than or equal to 5.0% niobium; less than or equal to 2.5% carbon; 3.0 to 20.0% of at least one element selected from the group consisting of molybdenum, tungsten, and vanadium; 0.5 to 5.0% manganese and/or 0.5 to 5.0% tin; balance copper; and inevitable impurities, and has a matrix and hard particles dispersed in the matrix, when niobium is contained, the hard particles contain niobium carbide and at least one compound selected from the group consisting of Nb—C—Mo, Nb—C—W, and Nb—C—V around the niobium carbide, and when niobium is not contained, the hard particles contain at least one compound selected from the group consisting of molybdenum carbide, tungsten carbide, and vanadium carbide.

1 . A wear-resistant copper-base alloy comprising, by mass %: 5.0 to 30.0% nickel; 0.5 to 5.0% silicon; 3.0 to 20.0% iron; less than 1.0% chromium; less than or equal to 5.0% niobium; less than or equal to 2.5% carbon; 3.0 to 20.0% of at least one element selected from the group consisting of molybdenum, tungsten, and vanadium; 0.5 to 5.0% manganese and/or 0.5 to 5.0% tin; balance copper; and inevitable impurities, wherein: the wear-resistant copper-base alloy has a matrix and hard particles dispersed in the matrix, when niobium is contained, the hard particles contain niobium carbide and at least one compound selected from the group consisting of Nb—C—Mo, Nb—C—W, and Nb—C—V around the niobium carbide, and when niobium is not contained, the hard particles contain at least one compound selected from the group consisting of molybdenum carbide, tungsten carbide, and vanadium carbide. 2 . The wear-resistant copper-base alloy according to claim 1 , wherein a hardness of the matrix is 200 to 400 HV, a hardness of the hard particles is 500 to 1200 HV, and an area rate of the hard particles relative to a total area of the matrix and the hard particles is 5 to 50%. 3 . The wear-resistant copper-base alloy according to claim 1 , for use as an alloy for cladding. 4 . The wear-resistant copper-base alloy according to claim 1 , which forms a cladding layer. 5 . The wear-resistant copper-base alloy according to claim 1 , for use as a material for a valve gear member or a sliding member for an internal combustion engine. 6 . The wear-resistant copper-base alloy according to claim 2 , for use as an alloy for cladding. 7 . The wear-resistant copper-base alloy according to claim 2 , which forms a cladding layer. 8 . The wear-resistant copper-base alloy according to claim 2 , for use as a material for a valve gear member or a sliding member for an internal combustion engine.
