Abstract
This paper studies effect of ultra fine surface structures on friction coefficient. Ultra fine structure was fabricated on a soda glass plate by nano-forming method with-a knife edge diamond tool. Friction coefficient of the fabricated surface was measured by a friction tester both under dry condition or wet condition with kerosene. Results show that ultra fine structure increases friction coefficient under, dry condition, but reduces factional coefficient under wet condition. Indentation load and indentation pitch also change friction coefficient.
