The Influence of Gaseous Environment on the Self-Adhesion of Metals

Abstract

The self-adhesion of metal surfaces was measured in various gases with pressure, exposure duration, and temperature as variables. Aluminum, copper, gold, lead, magnesium, and titanium were studied in air, argon, carbon monoxide, ethylene, hydrogen, nitrogen, and oxygen. The results showed that loss of adhesion for a particular metal resulted from gas absorption on its contacting surface and that the effect of environment upon adhesion could be related to the heat of absorption for the particular metal-gas interaction.
