A New Multifunctional Tribometer With High Temperature Module

H. Yanar, M. Demirtas and G. Purcek, A new multifunctional tribometer with high temperature module, BalkanTRib'17, 9th International Conference of Tribology, September 13-15, 2017 in Cappadocia, Nevsehir, Turkey.

Abstract: This paper presents a new multifunctional tribometer (UTS TRIBOMETER T30-HT) with high temperature module for especially characterizing the tribological behaviors of materials of machine parts operated at high temperature environments such as internal combustion engines, steam turbines, jet engines and power plants. This tribometer allows user to make high temperature tribological tests according to ASTM-G99 standards at temperatures starting from room temperature up to 1000 °C with an accuracy of 1 °C by adapting an electric resistance furnance. The furnace with a PID controller can be operated either independent or dependent on the software of the tribometer. The high temperature module can be easily adapted to the multifunctional tribometer and removed after the tests. It is possible to carry out the friction and wear tests using the samples with various dimensions. The tribometer has a well-design special arm for measuring the friction force. While the friction force is precisely measured by inctive sensors placed on the arm, the depth of wear is also measured by a displacement sensor placed under this arm. The multifunctional tribometer has its own software called Turquoise V02 which allows users to control the experimental parameters. The data obtained during the test are presented graphically via this software. Furthermore, this tribometer simulates the different contact configurations such as pin/ball-on-disk and test types such as circular(ASTM-G99), linear reciprocating (ASTM G133) and block-on-ring (ASTM G77-98). Tribometer can be operated with or without lubricant according to appropriate standards inall modules except high temperature one. The test system has a tribocorrosion module to characterize tribological properties of materials into different elektrotribocorrosive media. Also, it is possible to adapt an environmental chamber to the tribometer in order to do the tests in the different atmospheric conditions.
Keywords: Multi-functional tribometer, high temperature tribology.
