Two kinds of plasma sprayed Cr2O3 coating specimens are tested with electro-mechanical impedance (EMI) method.Quantitative investigation on the relationship between PZT excitation voltage and sensitivity of EMI method is performed in the frequency range of 100-110 kHz,withWK6500B precision impedance analyzer and high excitation voltage electric impedance measurement system (HEVEIMS).
