The Study and Application of Bronze-Graphite Oil- Containing Self-Lubricating Composites

Several bronze-graphite oil-containing self-lubricating composites were developed by adding a moderate amount of tin, molybdenum disulfide and others. The test results shown that the mechanical strength and tribological properties of these composites were improved differently as compared with bronze-graphite matrix, and their oil-containing ratio and several typical mechanical properties are equal or superior to the level of the same kind of materials at home and abroad. The instances in this paper shown that the bronze-graphite oil-containing self-lubricating composites have wide range of application. Typical properties of several bronze-graphite oil-containing self-lubricating composites(impregnated with 20 machinery oils).The properties of several composites were listed as following table:
