Outgassing of stainless steel during sliding friction in ultra-high vacuum

Outgassing of SS surfaces under sliding friction in ultra-high vacuum has been studied by ad-desorption mass-spectrometry and Auger electron spectroscopy. Experiments have been performed at normal loads of the indent in the range from 0.02 up to 0.87N, sweeping frequencies from 48 to 124 min-1 and l...
