Studies on the Oxidation-Corrosion-Deposition and Thermal Stability Characteristics of MIL-L-7808-Type Lubricants

Abstract

The report describes test methods and procedures used in the study of the oxidation-corrosion-deposition (O-C-D) characteristics of aircraft turbine engine lubricants employing a glassware-type apparatus. Development and evaluation of a light meter device for quantitative measurement of glassware deposits are also discussed. An extensive experimental effort using eight MIL- L-7808-type lubricants is described. The study encompassed an investigation of the factors of time, temperature, moisture, and metal types in relation to lubricant breakdown in an oxidizing (air) atmosphere. A similar, less extensive program was conducted for four lubricants using an inert (nitrogen) atmosphere.
