Title:
SLIDING CONTACT POINT MATERIAL AND METHOD FOR MANUFACTURING SAME
Document Type and Number:
WIPO Patent Application WO/2017/130781
Kind Code:
A1
Abstract:
The present invention pertains to a sliding contact point material which is used for a motor component, particularly, for a brush and which comprises: 20.0-50.0 mass% of Pd; 0.6-3.0 mass% of Ni and/or Co in total concentration; and Ag and inevitable impurities that are residues. The sliding contact point material preferably includes additive elements M that are Sn and/or In, wherein the total concentration of the additive elements M is 0.1-3.0 mass%. In the case where the additive elements M are included, the sliding contact point material has, in an Ag alloy matrix, a material structure in which composite dispersion particles each including an intermetallic compound formed of Pd and an additive element M among the additive elements M are dispersed. In the composite dispersion particles, the ratio (KPd/KM) of the Pd content (mass%) to the additive element M content (mass%) is within a range of 2.4-3.6.
