Abstract
A device for testing the adherence of a coating to a material includes a cone section and roller for bending the material around the cone section. The bent piece has a sharp bend at one end and a gradual bend at the other end. The proximity to the sharp bend at which flaking of the coating from the substrate occurs is a measure of the adherence of the coating to the material.
