Elastic modulus of plasma sprayed NiCr coatings

Elastic modulus of plasma sprayed NiCr coatings was measured using ring compression test (RC approach). The modulus measured by RC approach was compared with that obtained by the tensile test. The results show that the data obtained by RC approach are consistent well with those reported in the literature, which demonstrates the feasibility of RC approach for the determination of elastic modulus. The modulus measured by RC approach is between the value of perpendicular and parallel to the deposition obtained by the tensile test, which shows the modulus measured by RC approach is integrated results in the two directions.
