These coatings were subjected to annealing to final temperatures in the range from 500 °C to 1000 °C. It was found that the as deposited Mo-B-C coatings exhibited hardness of ~20 GPa, nanocomposite microstructure with very fine grains (~2 nm) and low degree of crystallinity. The X-ray diffraction and transmission electron microscopy together with selective area electron diffraction were used to study the temperature induced changes of the micro-structure of the coating and its crystallinity. The annealing process significantly improved the hardness (from ~20 GPa to ~30 GPa) and effective elastic modulus (from initial 330 GPa -500 GPa) of coatings while their resistance to fracture was kept sufficiently high.
