| Research Abstract |
A friction behavior of close-surface-modified amorphous carbon coating by copper metal has shown the characteristic feature in ultra high vacuum environment. We have observed that the cupper thin film was formed after the point-contact friction tests. The scenario can be that the copper grains were selectively transferred to the counter material and formed the metallic film. It can be understood that friction behavior of metal-containing amorphous carbon coating is well influenced by the shearing force of transferred metal.
