The method of tribotesting of PVD coated elements in oscillation motion at high temperature

The development of new types of coatings is realised by many scientific and technological centres in numerous countries. To evaluate new material solutions, researchers use various methods with wide range of tribotesters. Consequently, the obtained results are incomparable. The barrier of new technologies development, especially surface modifications dedicated to work at high temperatures, is a lack of worldwide recognised tribological test methods. This paper presents the method for tribological evaluation of tribosystems with PVD/CVD coated elements, in oscillatory motion and at high temperature (up to 900 °C). The method is realised by using SRV Optimol Instruments Prüftechnik GmbH (Germany) device. The realised verification tests proved the correctness of the elaborated methodology.
