Notes:
A new method has been developed to measure exo-electron emissions stimulated by frictional heating for a ball-on-disk sliding where a tungsten carbide was biased at +15 V dc to collect exo-electrons emitted from a γ-irradiated hot-pressed alumina disk. Exo-electron emission's signals were detected above a certain critical velocity when the contact surface was frictionally heated to a critical temperature of 250 °C and emitted exo-electrons. Sliding temperatures at any conditions of load and velocity were thus estimated using the temperature calculation program M. F. Ashby, J. Abulawi, and H. S. Kong [T-MAPS Background Reading and User Manual, Cambridge University Engineering Department (Cambridge University, London, 1992); Tribology Trans. 34, 577 (1991)]. This method provides a versatile method of measuring the sliding temperature of ceramics. © 1995 American Institute of Physics.
