Thermally stimulated electron emission of 40Kh10G10 steel samples subjected to sliding friction at different sliding velocities Nu was studied in a vacuum using a secondary electron multiplier. Also measured were the magnitude of induced wear, intermediate contact electrical resistance, the coefficient of friction, and the emf occurring under friction. As Nu increases from 0.75 to 4.5 msec, two maxima appear on the thermally stimulated electron emission curves in the regions 170 and 270 degrees C. A more intense thermally stimulated electron emission is observed after sliding with V equals 4.5 msec, and this also produces greater wear.
