CHARACTERIZATION OF THE DAMAGE TOLERANCE OF NANODESIGNED COATINGS BASED ON HIGH ENTROPY ALLOYS

Coatings are primarily designed to offer excellent wear and corrosion resistance. However, these properties are adjusted at the expense of the damage tolerance of the materials applied. By introducing the concept of high entropy alloys new property combinations are expected. In this contribution coatings composed of purely refractory HEA nitride as well as coatings containing non-refractory elements such as Al or Si will be presented. The focus is on a comparison of different experimental strategies to evaluate the damage tolerance of these coatings.
