Abstract The present invention belongs to the field of coating boanding strength test technology. The sample of said invention is formed from a support ring with upper taper hole and lower taper hole and a plug inserted into lower taper hole of said support ring. Said invented test method inclues the following steps: (1). inserting the taper body of the plug into lower taper hole of support ring and spraying coating layer to be tested on the upper surface of the support ring; (2). sticking a reinforced plate on the surface of coating layer; (3) fixing the sample on the tensile measuring device and applying force upward from undersurface of support ring, and applying force downward by holding plug so as to measure bounding strength of coating. Its measured result is not limited by tensile strength of adhesive, and said invention can be used for measuring bounding strength of hot-sprayed coating with high bounding strength.
