At present coating materials are widely used in the field of aerospace, machinery, petroleum, chemical, nuclear power. The strength and failure analysis of coating is more and more important, at the same time the coating mechanical properties are critical for guiding the industrial electroplating. The elastic constant is one of the most important mechanical properties of parameters that are needed to be evaluated. The paper presents the measurement method of elastic constants for coating material based acoustic microscopy technology. The elastic constants of different thickness semi-infinite nickel coating materials are test by the V(f, z) analytical method, it’s a frequency domain method; which is to obtain the experimental dispersion curves. The mechanical properties of the nickel coating can be inversed by changing the longitudinal wave velocity and shear wave velocity of nickel coating to fit the theoretical dispersion curves with the experimental dispersion curves. The experimental results show the method is feasible, this study lays a foundation for evaluating mechanical properties for semi-infinite coating materials.
