摘要：

Thin films of pure molybdenum oxide MoO3, vanadium oxide V2O5 as well as phases originating from Ag2O-MoO3, CU-V2O5 and Ag-V2O5 systems were deposited on alumina substrates by means of reactive magnetron sputtering. Structure and phase composition of deposits were characterised by X-ray diffraction (XRD) and Raman spectroscopy. High temperature (100-700degreesC) friction tests were performed using ball-on-disc configuration in air of normal humidity. Among studied phases, the best results were observed for silver molybdate (Ag2MoO4) and vanadium oxide bronze (beta-Ag0.33V2O5) coatings, which were chemically stable and allowed to decrease friction coefficient to the level of 0.2 at 450 and 600degreesC, respectively.
