dc.description.abstractDuctile materials have been used for dry gas seal mating rings to replace conventional sintered materials that have experienced occasional brittle fracture. The ductile materials require a coating to make them suitable for dry gas seal designs. This paper describes the dynamic ion beam mixing (DM) technique as an improvement in coating technology. Excellent tribological properties of thin titanium nitride (TiN) films formed by the dynamic ion beam mixing technique (DM/TiN) are demonstrated. Further, performance of a dry gas seal provided with a mating ring comprising a martensitic stainless steel substrate, having a DM/TiN coating formed thereon, is demonstrated, while making a comparison with the performance of a dry gas seal utilizing conventional materials. Considerations necessary for designing the ductile mating ring, its durability under abnormal and severe conditions, testing of the DM coating, and results of field experience are also discussed, together with problems accompanying the use of ductile materials.en
