High-Temperature Lubricant Analyses Using the System for Thermal DiagnosticStudies (STDS). A Feasibility Study

摘要

Increased importance has been focused upon the development of lubricants whichcan withstand more intense thermal exposures. Accordingly, a study was undertaken to determine the applicability of experimentally evaluating the high-temperature degradation properties of various lubricants using a System for Thermal Diagnostic Studies (STDS). With recent advances in instrumental chemical analysis techniques and associated instrumentation assemblies, it was considered highly probable that improved measurement and characterization techniques could be implemented for evaluating current and future high-performance aircraft lubricants. Therefore, four different lubricant samples were selected and subsequently tested using the STDS, which is an in-line system that performs both the thermal stressing function and the subsequent instrumental chemical analyses.
