The BC-2 ball crater equipment is designed for producing a taper section on a coated sample to enable analysis of coating properties such as coating thickness, wear, interface sharpness, layer thickness and coating adhesion.
The principle of the calo test is to determine the thickness of thin films. A hardened steel ball is turned in order to grind the layer.
Since main films are harder than the steel ball used, additional diamond paste is placed between the film and the steel ball. Once the film has been abraded off, the projection surface can be evaluated.
