Patterning and coating of sliding surface are important tribotecuniques to contribute to resource saving and energy conservation. We evaluated friction and wear characteristics of nano-pattern on cast iron substrate fabricated by the combination of shot-blast treatment and physical vapor deposition (PVD) of Au and Fe using a ball-on-plate reciprocating tribotester (SRV tribotester). As a result, the surface with nano-patterning showed lower friction coefficients than the surface with only shot-blast treatment and the untreated surface under dry and lubricated conditions. The Au layer was thought to function as solid lubricant especially in case of dry condition. Additionally, there was a possibility that an effect of oil sump induced by the multilayer structure decreased friction coefficients in case of lubricated condition.
