Elastic constants of several kinds of Ni-P composite coatings are determined using a surface acoustic wave spectroscopy, and the ultrasonically determined Young's moduli are compared with mechanically determined ones using a nanoindentation in order to examine the validity of the measured values. The experimental results have shown that the Young's moduli determined ultrasonically and mechanically almost agree with each other. The results have also clearly shown that increasing SiC particles content causes an increase in Young's modulus of the composite coating and the Young's modulus is decreased by increasing Teflon particles content. These results are in agreement with the theoretically estimated ones. Thus, the dispersion effect of hard or soft inclusions to the elastic property of composite coating has been shown quantitatively.
