Friction coefficient gold on gold

WebThe friction, wear, and contact resistance of lubricated sliding gold contacts at low energy circuit conditions have been studied with representatives of the major fluid chemical types. An understanding of the basic phenomena of lubricated sliding has been developed, and compared with details of unlubricated sliding. WebThe friction coefficient here showed between 0.8 and 2.0. Figure 6 demonstrates the influence of PCB materials and load acting on the friction pair on the friction coefficient. The friction ...
