Examination of the coating of a cutting tool based on measurements microhardness and scratch tests

Resumo

Methods of measuring and analyzing the wear resistance of the cutting tool coatings have been described in the article. Physical and mechanical properties of the surface has been determined by measuring the Vickers hardness test and based on the Oliver–Pharr model. Surface scratch test was performed with a variable load. Profilometry of the surfaces was carried out before the scratch test and the resulting scratches along. The quality of the coatings applied on the surface has been estimated.
