RÉSUMÉ

Nb−Al−N films were deposited by magnetron sputtering of Nb and Al in an atmosphere of Ar−N2 onto silicon wafers, at different currents of magnetron power supply, on which an aluminum (IAl) target is mounted. The films were studied by X-ray diffractometry, nano- and microindentation. The size of nanocrystals, microstrain, nanohardness, and the elastic modulus are extremely dependent on IAl. The films exhibit nanohardness and Knoop hardness in the range 29−33.5 GPa and 46−48 GPa, respectively.
