抄録
To establish the shearing delamination strength evaluation method of thermal sprayed coating, the torsion pin test method with tension is developed. In this report, delamination strength of WC-12Co thermal sprayed coating is investigated experimentally and analytically. Stress distributions around interface edge on delaminated surfaces are analyzed by FEM and are approximated by using the expression σ=Kr^<-λ> where K means a size of the field of singular stress. Delamination of the coating has occurred at the interface edge of the pin. It was confirmed that the shearing delamination strength can be measured accurately. The delamination criteria can be expressed by the shear stress intensity factor (Ks) with tensile stress intensity factor (Ka) for combined loading mode I with III.
