Abstract : The formation of gases by sliding friction of self-lubricating material, Teflon filled with 25% carbon black, was investigated and the quantity and the composition of the gases evolved determined. By mass spectrometry, it was shown that all gases produced by the sliding process can be attributed to fragmentation of the Teflon molecule. At least 60% of the gases evolved during the sliding process condense on a copper surface cooled by liquid nitrogen. (Author)
