摘要
The friction and wear of graphitic carbons sliding against themselves or against a metal has been investigated as a function of the gaseous environment. Water vapour and oxygen are of prime importance in determining the behaviour of the contact in agreement with previous results. Hydrogen is effective in reducing friction only after it has been dissociated on a tungsten ribbon. The mechanism of reduction of friction by adsorbed gases is discussed in relation with the absorptive capacity of the third body layer. The action of hydrogen explains well the unusually good wear and friction properties of hydrogenated amorphous carbons. The use of modern surface analytical tools in elucidating the mechanisms of friction and wear is discussed.
