Friction behavior of silicon in contact with titanium, nickel, silver, and copper

Technical Report ·
OSTI ID:7003917

This paper describes the friction behavior of single crystal silicon rubbed against the pure metal titanium, nickel, silver, and copper in room air under both dry and lubricated conditions. The metallic pin specimens moved in reciprocating sliding 30 cycles (60 passes) on the same path in the parallel direction on the silicon surface. Results indicate that the friction coefficient in dry sliding is controlled by adhesion and the surface chemical activity of the metal. With mineral oil lubrication, the silicon behaved plastically. The wear tracks on the silicon surfaces were subsequently examined with the scanning electron microscope.
