ION-BOMBARDMENT-ENHANCEC DIFFUSION PHENOMENON IN Pb-Sn ALLOY

The surface phenomena of Pb-Sn alloy under the Ar⁺ ion bombardment have been investigated by using a PHI-590 scanning Auger microprobe at room temperature. Theoretical analysis of experimental data showed that ion-bombardment-enhanced diffusion had occurred with a diffusion coefficient up to 10^-15cm² /sec. A possible explanation is given.
