| abstract | ION BEAM MILLING OF SEAL RINGS Abstract of the Disclosure Fluid seals for use in rotary fluid machines (such as pumps, compressors or turbines) are disclosed. The seals contain a pair of seal rings. At least one of the seal rings contains indentations (or grooves) in the sealing surface which are configured in a geometric pattern. The grooved seal ring is characterized in that an ion beam milling process is used to form the grooves in the sealing surface. |
