Au-based clad composite material, producing method thereof and micromotor using the same

Year	Description
2001	Invention patented by Mii Matsuzawa, Hirotaka Sakamaki, and Osamu Matsuzawa on June 20th, 2001. Abstract: To provide a contact material suitable for a commutator of a micromotor which can improve wear resistance and prolong the life of the micromotor by improving an Au-based clad composite material provided at an outermost layer with Au or an Au alloy. The present invention provides the Au-based clad composite material including a surface of a contact substrate having an Ag--Cu--Si alloy layer cladded with Au or the Au alloy, wherein an intermetallic compound Cu--Si is dispersed and deposited in Au or the Au alloy.
