The influence of temperature on the tribological properties of polyoxymethylene (POM) materials

Polyoxymethylene (POM) has been widely used as a gear material owing to its excellent mechanical properties. One of the key parameters that influence the tribological properties of POM is the operating temperature. In this study, the tribological properties of POM under different operating temperatures (25–110 °C) were studied. The results showed that the friction and wear coefficients tend to increase with increasing temperature. The adhesive wear is the primary wear mechanism influenced by temperature and the adhesive wear increases with an increased temperature. Material transfer was found for all the velocity and load settings.
