SYNTHESIS OF FLUORINATED DIAMOND FILMS USING A LASER TECHNIQUE

A laser chemical vapour deposition process for growing fluorinated dia mond thin films on two bearing materials, SiC and 440 C stainless stee l, is described. The type of laser, carbon feedstock, laser-precursor gas interactions, and deposition conditions have been established. Ram an spectroscopy analysis revealed that the films' deposited on SiC con sisted of a mixture of diamond and graphite, while the films on 440 C steel were composed of diamond, diamond-like carbon and graphite. The feasibility of diamond formation using laser light-gas interactions is explained.
