The purpose of this study was to identify suitable alternative cleaning solvents and lubricants to replace l, l,2-trichloro-l,2,2-trifluoroethane CFC-ll3 and 1,1,1- trichloroethane TCA in mechanical degreasing operations, in an anti-seize material used to lubricate high-torque fittings, and in electrical cleaning operations. The study was conducted at the Engineering Propulsion Laboratory EPL Air Force Plant PJKS. Over sixty candidate materials were evaluated. This study was demonstrative not only in eliminating ODC usage but also in selecting materials which could improve cleaning and operational requirements. Because many of the analysis and test techniques can be easily integrated into other industry applications, investigation of these techniques in other aerospace industry programs and processes is recommended.
