The Calowear is an easy and straightforward instrument which characterizes the resistance to abrasion of a surface. Abrasive slurry is inserted into the contact between a coated sample and a rotating ball. Testing with these conditions results in a spherically shaped wear scar on the surface of the sample. The diameter of this wear scar gives a measurement of the amount of the worn material.
