A new self lubricating material has been assessed in a laboratory rig simulating high temperature piston rings for adiabatic diesel engines. The material consists of a solid metallic surface containing half millimetre diameter pockets filled with solid lubricant.The friction and wear properties of conventional piston ring surfaces were assessed at 380°C versus a chromium oxide counterface. This was followed by a study of the properties of various solid lubricant formulations which were then evaluated as fillers for surface pockets. The most promising solid lubricated materials contained molybdenum disulphide or lithium fluoride plus copper.
