Abstract

Two ultrasonic non-destructive evaluation methods were applied to characterize the mechanical properties of nano-structured diamond-like carbon hard coatings in this work. Guided-wave phase velocity spectra were measured using the photoacoustic guided-wave technique and Line-focus Acoustic Microscopy. The measured dispersion curves by the two methods were independently analyzed by a nonlinear optimization approach using an appropriate multi-layer material model. The measured Young's moduli using the ultrasonic techniques were compared with nano-indentation tests and good quantitative agreement was found.
