| Research Abstract |
Lubrication properties of two kinds of copper molybdates as a solid lubricant which can be used in the high temperature atmosphere were investigated. Copper molybdates showed excellent lubricity with the increasing temperature up to 700 °C and drastically decreased wear amount of stainless steel friction pair. This lubrication property was superior to the lubricity of copper oxide or molybdenum trioxide which shows good lubricity under high temperature atmosphere. It was suggested that the generation of metal copper as a result of reduction reaction could be one of the reason for excellent lubricity at high temperature.
