Research Abstract

For the purpose of establishing an innovative surface texturing techniques in order to reduce the friction loss of mechanical systems, the concept of the multi-scale surface texturing have been studied by developing a complex texturing technology that combines a laser micro-fabrication and a coating technique. Computer Fluid Dynamics (CFD) analysis has been applied to optimize the texturing pattern on the sliding surface. By verifying the tribological properties of the textured surface experimentally, CFD tools has been modified to improve the simulation accuracy. As a result, in the lubricating system with low viscosity oils, we have succeeded to improve the seizure properties of copper alloy significantly by promoting the transition of the lubrication state from the boundary to the hydrodynamic according to a novel concept of surface texturing.
