The Dissolution of Carbon Adlayers into the (110) Face of Nickel.
Abstract
The rate of carbon dissolution from adsorbed layers through the (110) face of a nickel crystal has been measured for a wide range of initial surface carbon concentrations over the temperature range from 600 to 913K. Auger electron spectrometry was used to measure the decrease in surface carbon concentration with time at temperature. For graphitic monolayers at T greater than 873K, dissolution is controlled by the transport of carbon from adsorbed layer to bulk. For dilute adlayers at T approximately 723K, dissolution is controlled by the bulk diffusion rate of carbon. At intermediate values of initial carbon concentration and temperture, quantitative treatment of the dissolution rate was not possible. (Author)
