- The primary focus of this investigation is on tribological properties of plasma nitrided and post-oxidized tool steels during sliding against ultra-high-strength boron steel. The experimental work has been carried out at room temperature and at 400 °C by using a high-temperature pin on disc tribometer. The experimental materials were tool steels of three different compositions, which were plasma nitrided and post-oxidized at 500 °C. One of the tool steels was also post-oxidized at 480 and 520 °C. The results have shown that the friction and wear characteristics are influenced by the test temperature and the post-oxidizing temperature. The tool steel, post-oxidized at 500 °C, resulted in better friction and wear performance at room temperature and also improved wear resistance at elevated temperature. The observed wear mechanisms are mainly adhesive at room temperature and a combination of adhesive and abrasive at elevated temperature.
