High temperature tribometer is used to evaluate the tribological properties of engineering materials under high temperature conditions. In the present paper, the virtual instrumental testing system of the tribometer was developed with LabVIEW software as it calls the dynamic link library to drive the normal data acquisition card. The system is designed for getting the information about coefficient of friction, temperature, velocity and load of data acquisition, data treatment, graphic displaying, data storaging and report generating. The friction and wear tests were carried out by the pin-on-disc tribometer with this testing system. The experimental results show that the testing system is stable, accurate and reliable.
