Abstract
THE OBJECTIVE OF THE PROPOSED PROGRAM IS TO PREPARE AND EVALUATE A SERIES OF OXIDATION, CORROSION, AND WEAR INHIBITING ADDITIVES FOR CTFE FLUIDS EFFECTIVE AT >275F. THE CANDIDATE ADDITIVES ARE MONO- AND DIPHOSPHA-S-TRIAZINES SUBSTITUTED ON THE PHOSPHORUS ATOMS BY PHENYL AND/OR THIO-GROUPS AND BY PERFLUOROALKYL OR PERFLUOROALKYLETHER GROUPS ON THE CARBON RING ATOMS. THE MATERIALS CONTAINING PHENYL-SUBSTITUTED PHOSPHORUS RING ATOMS WERE SHOWN TO BE EFFECTIVE ANTI-CORROSION AND ANTI-OXIDATION AGENTS IN PERFLUOROALKYLETHER FLUIDS; THE PRESENCE OF PERFLUOROALKYL OR PERFLUOROALKYLETHER CHAINS IS BELIEVED TO ASSURE SOLUBILITY IN CTFE. ADDITIVE-CTFE FLUID FORMULATIONS WILL BE EVALUATED USING SELECTED METALS AND ALLOYS IN A MICRO-OXIDATION-CORROSION TEST ASSEMBLY, AS WELL AS "DIP-COATED" METAL SPECIMENS EXPOSED TO A 100% HUMIDITY ENVIRONMENT AT 158F. SELECTED FORMULATIONS WILL FURTHERMORE BE SUBJECTED TO 4-BALL WEAR TESTS TO EVALUATE THE LUBRICITY AND FILM FORMING CHARACTERISTICS OF THE DEVELOPED ADDITIVES. BASED ON THE TEST RESULTS, OPTIMUM ADDITIVES WILL BE DEVELOPED.
