Abstract
To establish the adhesive strength evaluation method of thin coating layer with high adhesive strength, thermal sprayed coatings were tested by the newly proposed torsion pin test method. In this study, adhesive tensile strength of WC-12Co thermal sprayed coating is also investigated experimentally and analytically. Stress distributions at crack tip singular point on fractured interface are analyzed by FEM. It is found that the torsion pin test method is very useful to evaluate shear adhesive strength precisely by small number of specimen.
