Document Type and Number:
Japanese Patent JP6941663
Kind Code:
B2
Abstract:
A sliding contact material that is used for a constituent material, particularly a brush, of a motor. The sliding contact material includes: Pd in an amount of 20.0% by mass or more and 50.0% by mass or less; Ni and/or Co in an amount of 0.6% by mass or more and 3.0% by mass or less in terms of a total concentration; and Ag and inevitable impurities as a balance. Preferably, the sliding contact material further contains an additive element M including at least one of Sn and In, and the total concentration of the additive element M is 0.1% by mass or more and 3.0% by mass or less. When containing the additive element M, the sliding contact material has material structures in which composite dispersed particles containing an intermetallic compound of Pd and the additive element M are dispersed in an Ag alloy matrix, and the ratio (KPd/KM) of the content (% by mass) of Pd and the content (% by mass) of the additive element M in the composite dispersed particles is within a range of 2.4 or more and 3.6 or less.
