Abstract
Zirconium carbosulfides with various compositions have been produced by the combustion synthesis. In this study, molybdenum powders were added into the Zr-C-S reaction system to inhibit its intensive reactivity. The raw powder mixtures were pressed into pellets, followed by the combustion synthesis. It was revealed that Zr4C2S2 phase was formed with extra carbide phases in the obtained products. Hardness values of the products increased with a quantity of the added Mo, which suggested occurrence of solid solution hardening. SEM and TEM observations showed that some of the products had layered structures, which is expected as one of the promising solid lubricants.
