| Outline of Final Research Achievements |
To achieve low friction coefficient without lubrication, fine projections were formed on the coatings. Nano-wires were grown at the interface to form fine projections. The result showed that the delamination strength of the coatings was increased by the projections.
Friction coefficient was influenced by the height of the fine projections, and the minimum friction coefficient was observed when the average height of the projection was around 0.5 micrometer. Density of the nano-wires was one of important factors, and increase in density was achieved by optimizing discharging condition.
