Determination of Conditions for Evaluating Friction-Wear Properties of Coatings

Abstract

This study was conducted to investigate the determination of the conditions for evaluation friction-wear properties of the thin layers and coatings on structural 16MnCr5 steel. The AlCrVN coatings with the thickness of 2.0 µm were generated on the un-nitrided and nitrided materials under the same conditions. The frictionwear properties of the layers and coatings were evaluated by the ball-on-flat method on The Universal Mechanical Tester 3 (UMT-3) with different test forces. The obtained results showed that the friction-wear properties of AlCrVN-coated materials changed markedly when the force reaches a certain value. The most suitable conditions for evaluating the properties of thin hard coatings have been determined.
