JPS5970737A - Sliding contact material - Google Patents

Abstract

PURPOSE:To obtain a sliding contact material having an increased softening temp. and producing oxide which acts as a lubricant to improve the wear resistance by adding a specified percentage of one or more among Co, Sn, and Ti to an alloy material consisting of prescribed percentages of Au, Pt, Pd, Ag, Cu and Zn. CONSTITUTION:The sliding contact material is obtd. by adding 0.5-15% one or more among Co, Sn and Ti to an alloy material consisting of, by weight, 9-11% Au, 9-11% Pt, 34-36% Pd, 29-31% Ag, 13-15% Cu and 0.5-1.5% Zn. A brush contact made of the contact material undergoes much less wear than a brush contact made of a conventional material and has low and stable contact resistance. Accordingly, the formation of powder due to wear is remarkably reduced, and noise is hardly generated. This brush contact is equal to the conventional brush contact in contact resistance.

Go, Sn, i'' without changing the composition ratio to an alloy material consisting of 14% weight, 9% weight 29-31 weight, 13-15 weight % Cu, and 0.5-1.5 weight % Zn. The reason why at least one type of j is added by 0.5 to 15% by weight is,
This is to increase the softening temperature of the alloy material and improve the adhesion resistance.If it is less than 0.5% by weight, it will not be effective, and if it exceeds 15% by weight, the amount of oxidized p generated will increase. If the contact resistance increases, the contact resistance will increase, and it will become unstable.
