Raman and Confocal Microscopy

Mechanical Face Seals are often used in compressors and in the chemical industry to prevent oils or other liquids from leaking from the system and possibly contaminating the surrounding environment. A custom built mechanical face seal test rig is used to investigate the friction and wear properties of such seals.
