The aim of the present work was to study the mechanical properties of thin nanocomposite
Mo-B-C coatings consisting of nanocrystalline Mo2BC embedded in amorphous Mo-B-C
matrix. Magnetron sputtering of three targets, B4C, C and Mo, was used for coatings preparation. The Mo-B-C coatings were deposited on high speed steel substrates. The fracture resistance of Mo-B-C coatings was studied by both indentation and dynamic impact tests. The impact tests enabled us to predict the load limit causing the coating destruction.
