This paper is concerned with materials used for the seal components of mechanical seals. Mechanical seals are used for rotary seals of fluid machinery in various industries. Their service conditions, such as sliding rate, temperatures and pressure, have been changed to severe in recent years. The sliding surfaces are the most critical part of a seal, and are mainly required tribological properties. Sliding surfaces are subject to chemical attack under the various fluid conditions in the service. Therefore corrosion properties must be taken into consideration in selecting materials for the seals.
