A FRICTION AND WEAR STUDY OF CARBON IN SLIDING CONTACT WITH METAL

Abstract

This investigation concerns the mechanical wear of carbon in sliding contact with metal. The combinations of carbon and metal materials tested were some of those normally used for mechanical seal applications. The investigation was carried out in two phases: various combinations of carbon and metal were tested to determine which performed best on the basis of wear rate and friction; the selected combination of materials was further tested to determine the predominant test parameters affecting wear rate and friction. It was found that carbon wear rate is more dependent on contact pressure than applied load. It was also found that wear rate and friction increase with decreasing speed. This evidence indicates that the establishment of a boundary film was of importance in this investigation. A cross cylinder testing apparatus built at the United States Naval Postgraduate School was used for testing.
