Frictional properties of Fe5Si3 dispersed Si3N4 were investigated using polyolester and normal oil with additives as lubricants; the following results were obtained: 1) when polyolester was used, Fe5Si3 dispersed Si3N4 showed obviously lower friction coefficient than cast iron while friction coefficient of both materials were almost the same under normal oil testing conditions; 2) chemical analysis proved that a relatively high amount of calcium-sulphonate as detergent-dispersant existed on wear track of Fe5Si3 dispersed Si3N4, while oiliness-agent was not detected. Those results suggested that adhering of calcium-sulphonate to the surface of Fe5Si3 dispersed Si3N4 reduced oiliness and raised the friction coefficient.
