In this paper, the structure and tribological properties of synthetic MoS2 film prepared by a novel compound technology—combining magnetron sputtering with low temperature ion sulfurizing were investigated. X-ray diffraction (XRD) pattern for the MoS2 film implies that the film mainly consists of Mo and MoS2 phases. The hardness of the synthetic MoS2 film was 7.44 GPa which was higher than that of the FeS film. The sliding tribological behavior of the MoS2 film was studied by ball-on-disc tests. The results showed that the synthetic MoS2 film possessed excellent friction-reducing and wear-resisting properties. In addition, the tribological behaviors of the MoS2 film were superior to those of the FeS film and original 1045 steel.

Mn-Zn ferrites with different doping contents of W6+ ions were prepared by using standard ceramic technique. The microstructure and magnetic properties of the as-prepared Mn-Zn ferrites were investigated. It was found that all the samples with different contents of W6+ ions consisted of ferrite phase of typical spinel cubic structure. With increasing doping content of W6+ ions, the lattice constant of the ferrites decreased but the grain size increased. Through the measurement of magnetic properties, it was revealed that the saturation magnetization and initial permeability of the samples increased with small doping content of W6+ ions but decreased with additional doping, and the Curie temperature decreased monotonously with W6+ ion doping.
