Abstract

Laser-induced transient reflecting grating (TRG) technique was applied to measure both nitrogen-ion-implanted and nonimplanted thin-film coatings (thickness, 40nm) of diamond-like-carbon (DLC). Different TRG responses corresponding to the different samples with a variety of nitrogen-ion implantation doses were observed and the hypersonic surface acoustic wave velocities were obtained with a variety of wavelengths. A phenomenon was observed that the SAW velocity of the implanted DLC coating with higher dose became larger than that of the nonimplanted sample.
