Geometric influence on friction and wear performance of cast iron with a micro-dimpled surface

Geometric influences on the tribological performances of cast iron with a micro-dimpled texture are researched experimentally. The friction coefficients are measured on four different dimpled shapes with various geometrical parameters with the changing of operating load and rotation speed by a ring-...
