Thermal stability of hard nanocomposite Mo-B-C coatings
Popis výsledku v původním jazyce
In the present work, nanocomposite Mo-B-C coatings were deposited on high speed steel and hard metal substrates by magnetron sputtering of three targets. These coatings were subjected to annealing to final temperatures in the range from 500 degrees C to 1000 degrees C. It was found that the as deposited Mo-B-C coatings exhibited hardness of similar to 20 GPa, nanocomposite microstructure with very fine grains (similar to 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 microstructure of the coating and its crystallinity. The annealing process significantly improved the hardness (from similar to 20 GPa to similar to 30 GPa) and effective elastic modulus (from initial 330 GPa-500 GPa) of coatings while their resistance to fracture was kept sufficiently high.
