Abstract: Pulsed-laser-arc deposition technique was introduced. Diamond like carbon (DLC) films were deposited on Si<111> and Si<100> respectively. Results of laser
raman spectroscopy showed that the as-deposit films were amorphous, having obvious sp3 structure. Meanwhile, surface topography and micro-tribological
character were investigated by using atomic force microscope and nano-scratch tester. The results show that the surface microstructure and micro-tribological
character of the film deposited on Si<100> is better than that deposited on Si<111>. The average friction coefficient of the film on Si<100> is 0.036.

Key words: pulsed-laser-arc, diamond like carbon film, laser raman spectroscopy, friction coefficient
