Molybdenum disulfide is a layered transition-metal dichalcogenide semiconductor that is attracting renewed attention for its potential use in future nanoscale electronics, optoelectronics, catalysis, tribology, and other fields. In all of these cases, the interaction between MoS 2 and various transition metals is very important. In this work we survey the thermodynamics of the metal-Mo-S systems and the anticipated reaction products from transition metals and MoS 2 . We examined over 200 references on the reactions between transitions metals (M) and MoS 2 , compiled thermodynamic data, and used the thermodynamic data to predict M-Mo-S ternary phase diagrams for systems without experimentally determined diagrams. Where possible, experimental literature on the interactions between metals and MoS 2 was used to corroborate our predicted diagrams and stable reaction products. Both the previously reported and newly predicted M-Mo-S phase diagrams fall into three categories. In the first category, the metal is in thermodynamic equilibrium with MoS 2 . In another, there is a driving force for the metal to reduce MoS 2 , with tie lines to sulfides of the contact metal dominating the phase diagram. In a final category, there is a very stable solid solution or ternary phase that dominates the phase diagram. Better understanding of the phase equilibria in the M-Mo-S systems will aid research on the use of MoS 2 in a variety of fields.

Novel siliconized Mo-Re coatings dedicated to applications in the glass industry are shown in this paper. The study aims at the characterization of morphology, phase composition, and oxidation behavior of siliconized Mo-based coatings deposited on a ceramic-metal substrate. Two coatings with different contents of rhenium were prepared using a hybrid process that includes atmospheric plasma spraying and pack siliconizing. The microstructure, chemical, and phase composition of the obtained coatings were characterized and compared to Mo coating. Moreover, a characterization of starting powders was performed. After the description of the coatings' microstructure, oxidation tests were carried out at 1000, 1100, and 1200°C. The surface condition of oxidized coatings was investigated. The structure of Re-containing coatings after the siliconizing process was comparable. Both were composed of Mo and (Mo,Re)Si 2 -ReSi 1.75 layers. However, in the case of Mo-44Re (wt.%) coating, a higher concentration of rhenium silicide was observed compared to that of coating containing 15% Re. The Re-containing silicide layers were characterized by a presence of lower content of hexagonal MoSi 2 compared to that of non-alloyed MoSi 2 . The oxidation resistance of both coatings containing rhenium was comparable; however, the one with a higher amount of Re exhibited slightly higher durability in high-temperature oxidation.
