The goal of the present study was to analyze the influence of temperature on the static friction coefficient, which is important during the start-up of machine and equipment components. Thermoplastic materials: PA6, PEEK and PTFE were tested. These materials cooperated with typical C-45 structural steel using a pin-on-disc association. The sliding pairs were placed in a climatic chamber in which tests were carried out in the temperature range from +20 ÂşC to -50 ÂşC. The obtained results allowed to determine the static friction coefficient for each sliding pair. The tests were supplemented with microscopic images of the surface and microhardness measurements.
