| Research Abstract |
Low friction mechanism of hydrogenated Diamond-Like Carbon(a-C : H) was assumed that sp^3 structures were destructed to graphite-like having low shearing strength. We prepared PECVD a-C : H coatings which were irradiated with UV. These specimens and as-deposited a-C : H tested, during 250 to 4500 cycles, friction coefficient of 254 and 312 nm UV irradiated a-C : H exhibited 0. 02 to 0. 05.
