A TECHNIQUE FOR MEASURING CAPTURE COEFFICIENTS AND APPLICATION TO THE MEASUREMENT OF HYDROGEN ADSORPTION BY TITANIUM

Abstract

The problems encountered in making capture coefficient measurements are reviewed, and a new experimental technique, employing a rotating gage, is presented. Utilizing this technique, the fraction of impinging hydrogen molecules removed by a continuously deposited titanium surface was determined as a function of the titanium evaporation rate and gas flux. The results demonstrate that there is little to be gained by evaporating more than one atom of titanium for each atom of hydrogen.
