| Research Abstract |
We could obtain stably Cr sulfide, Ti and Zr-systems carbosulfides by using the combustion synthesis method. From the transmission electron microscopy, the layered structures were observed in the carbosulfides, as well as MoS2 of the typical solid lubricant. The high-temperature oxidation resistance tests showed that the carbosulfides were difficult to use as dispersants for improving machinability of steel under an oxidation atmosphere because their oxidation resistance degraded over 500℃. On the other hand, their dynamic friction coefficient,μ, indicated 0.11 to 0.12, which was equivalent to MoS2.Finally, it was concluded that the sulfide and carbosulfides could be expected sufficiently as one of the promising solid lubricants.
