Results of oxidation-corrosion test evaluations on numerous aircraft turbine engine lubricants are given. Lubricant types include those related to four specifications as well as a number of experimental-type fluids such as polyphenyl ethers. Blends of selected lubricants were also examined. Test conditions were varied extensively in the study, with emphasis on the parameters of time, temperature, airflow, metals, and reflux of condensable sample vapors. A major objective in investigations with conventional, ester-type lubricants was a comparison of relative performance for test series of short duration and high temperature versus long duration (26 days) and relatively low temperature. In addition, several experimental-type fluids were evaluated in a test series over a temperature range of 600 to 680F. This investigation was mainly concerned with performance effects due to variation of metal types in the corrosion specimen set. The applicability of electrocleaning of metal specimens was also explored with regard to improvement of the repeatability of corrosion data.
