Thermal analysis of synthetic lubricating oils with DSC and TGA

摘要

Thermal stability of selected lubricating oils was studied using thermoanalytical methods Differential Scanning Calorimetry (DSC) and Thermogravimetricla Analysis (TGA). The ways worked out allow fast estimation of different base oils and additives especially under influence of CO{sub}2. Based on heating curves thermal decomposition and evaoporation reactions can be interpreted. Relations between chemical structure and thermal stability of synthetic lubricants result.
