Improvement of Lubrication Performance by Micro Pit Surfaces

This paper describes an investigation on improvement of lubrication performance by incorporating micropits on a surface with special focus on the arrangement of the micropits. Water lubricated experiments were conducted using a test rig in which parallel conformal sliding motion was produced between...
