Abstract

Disclosed are a testing device and a testing method for adhesive strength of an inner hole coating. A pull rod of the testing device for the adhesive strength of the inner hole coating may apply an axial tension to the inner hole coating via a guide ring and an assisting assembly, and may also apply radial pressure to the inner hole coating via a tapered surface and the assisting assembly. And the press rod may apply a radial tension to the inner hole coating via the pull hook and the assisting assembly. The testing method for the adhesive strength of the inner hole coating adopts the above-mentioned testing device for adhesive strength of an inner hole coating, a tensile adhesive strength test and a shear adhesive strength test may be performed on a same device.
