Abstract
AbstractThe versatility of a differential scanning calorimetry (DSC) cell in studying thermal and/or thermal‐oxidative degradation of lubricants is shown using ester‐based aviation turbine oils as an example.The following applications are discussed: 1. quality control of fresh and used oils by pressure differential scanning calorimetry; 2. influence of metal catalysis on oil degradation; 3. identification of volatile degradation products by PDSC gas chromatography‐mass spectrometry via a TENAX trap; 4. determination of spontaneous ignition temperatures; 5. influence of metall metal oxides, wear debris and oil degradation products on ignition behaviour; 6. inhibition of spontaneous ignition by antioxidants.
