摘要

The aim of this study has been to develop a new method of recording temperature fields over friction surfaces and within thin surface layers of friction pair elements. In this, the materials tested include steel, titanium, aluminium, silica glass, and sapphire. When studying the temperature distribution in the surface layers of mated bodies a pin-on-disc geometry is usde. The friction regimes are as follows: the sliding velocity is varied within the range 10-80 m/s and the nominal pressure is 0.06-0.5 MPa. Experiments have been performed using a set-up involving an optoelectronic scanning technique and comprising a high-speed friction machine and a temperature field recording system. The latter consists of an optoelectronic transducer, a monitor, a video tape recorder, an amplifier, a device to form oscillograms of image brightness, and a digital storage oscillograph.
