Corrosion and Lubricity Testing of Nonflammable USAF Formulated CTFE (chlorotrifluoroethylene) Base Hydraulic Fluid

Abstract

The objective of this study was to evaluate the antiwear and anticorrosion properties of the US Air Force's latest nonflammable hydraulic fluid formulation, a chlorotrifluroethylene oligimer containing an antiwear additive and an anticorrosion additive. This formulation, referred to as NFHF, is stable to 135 C. The NFHF was tested according to ASTMD1472 and D1748, the Federal Test Standard 791C Methods 5322.1 and 5308.6, and the corrosion rate evaluation procedure (CREP). The data contained in this report is compared with the chlorotrifluoroethylene with no additives and the present fire resistant hydraulic fluid military specification MIL-H-46170. The antiwear and anticorrosion properties of the formulated NFHF improved over the base fluid with no additives. Keywords: Fire safety; Corrosion inhibition; Fire resistant hydraulic fluid; Chlorotrifluoroethylene (CTFE), Nonflammable hydraulic fluid (NFHF), Hydraulic fluid, Halocarbons, Corrosion, Wear, Lubricity.
