Abstract

Nanocomposite films with unusual structures were synthesized by ablating a molybdenum disulfide target with pulsed intense ion beams and depositing the films on substrates kept at 573 K. Microstructure of the films was comprised of 10-100 nm size pure molybdenum boulders in an amorphous matrix of Mo and S, instead of a single homogeneous phase. Tribological studies indicate that frictional contact during the initial run-in period can transform the amorphous matrix into crystalline MoS2 with basal planes oriented along the direction of sliding. The films appear to have potential for low friction and low wear applications in harsh environments.
