Rapid growth of diamond-like-carbon films by copper vapor laser ablation

PDF Version Also Available for Download.

Description

Visible light from a copper vapor laser (CVL) operating with 510 and 578 nm radiation (intensity ratio approximately 2:1), an average power of 100 W, a pulse duration of 50 ns, and a repetition frequency of 4.4 kHz has been shown to produce high quality diamond-like-carbon (DLC) films at fluences between 2x10{sup 8} and 5x10{sup 10} W/cm{sup 2}. Maximum deposition rates of 2000 {mu}m{center_dot}cm{sup 2}/h were obtained at 5x10{sup 8} W/cm{sup 2}. DLC films with hardness values of approximately 60 GPa were characterized by a variety of techniques to confirm DLC character, hydrogen content, and surface morphology. The presence of ... continued below

DLC films with hardness values of approximately 60 GPa were characterized by a variety of techniques to confirm DLC character, hydrogen content, and surface morphology. The presence of C{sub 2} in the vapor plume was confirmed by the presence of the C{sub 2} Swan bands in emission spectra obtained during the process. Economic implications of process scale-up to industrially meaningful component sizes are presented.
