Abstract
The results of a study of the strength and erosive properties of ion plasma layered coatings of various metal and ceramic (nitride) systems are described. The total thickness of the coating is a few microns, while the thickness of each of the layers does not exceed two or three tens of nanometers. The use of different indentation schemes provides a set of physicomechanical properties responsible for the coating strength. The properties are subjected to multiparametric optimization to obtain a satisfactory correlation with the data of bench erosion tests of the coatings. It is found that the erosion resistance of nanocomposite coatings, which is commonly determined in complex bench or full-scale tests, can be reliably diagnosed from the set of the physicomechanical properties of the coatings measured in the laboratory.
