Popis:	Using the results of comparative analysis of the structure, mechanical behavior, and nanohardness of chromium and molybdenum coatings produced by the method of magnetron sputtering, we propose an original mechanism of the uncommonly high hardness of superfine-grained chromium. We have developed the concept of “useful” impurities, which enables one to obtain nanostructurized materials with high hardness (strength) by means of grain-boundary engineering.
