Flowserve Corporation signed a collaborative agreement with Advanced Diamond Technologies, Inc. (ADT) to become the exclusive developer and supplier of diamond coated hard faces for its mechanical seals.When applied to Flowserve base materials, the ultrananocrystalline-structured diamond (UNCD) coating developed by ADT produces an exceptionally hard surface with significantly improved friction and wear characteristics. This is particularly beneficial in services requiring protection from slurry, dry running conditions and resistance to chemical corrosion.
