Study on temperature-resistant properties of polymer-matrix solid film lubricants

The temperature-resistant properties of some polymer-matrix solid film lubricants were studied. Different chemically modified methods were used in this study to enhance, their temperature-resistant properties. The friction and wear mechanism of polymer-matrix solid film lubricants rubbing at different temperatures in air were explored with differential scanning calorimetry (DSC), scanning electron microscope (SEM), and X-ray photoelectron spectroscopy (XPS). The test results showed that the blending modification of polymer and the application of certain of filler were beneficial to enhance heat resistance of polymer-matrix solid film lubricants, and therefore, improved their lubricating properties at different temperatures in air.
