Surface damage of molybdenum and TZM alloy under D/sup +/ impact
The surface damage of polycrystalline molybdenum and TZM alloy under 40-, 60-, and 120-keV D/sup +/ impact has been investigated for irradition in both pulsed and continuous modes for total doses varying from 1.7 x 10/sup 1/7 to 2.2 x 10/sup 1/9 ions/cm/sup 2/ and for target temperature varying from ambient temperature to 400/sup 0/ C. Analysis by scanning electron microscopy of the Mo samples held at ambient temperatures during D/sup +/ irradiations in both pulsed and continuous modes revealed surface damage due to blistering for the 40- and 60-keV irradiations for doses ranging from 8.7 x 10/sup 1/7 to 8.1 x 10/sup 1/8 ions/cm/sup 2/, but no detectable damage for the 120-keV D/sup +/ irradiations for doses ranging from 4.3 x 10/sup 1/8 to 2.2 x 10/sup 1/9 ion/cm/sup 2/. This observed difference in the blistering behavior is attributed to the difference in the ambient target temperature for the 120-keV irradiation and both the 40- and 60-keV irradiations. For irradiations at temperatures above 300/sup 0/ C, no blisters could be detected for any of the three energies. For similar irradiation conditions, TZM alloy showed a reduction in blistering as compared to molybdenum.
