概要	Sputtering erosion and surface morphology of F82H and pure Fe irradiated by hydrogen and carbon mixed ion beam (1 keV H-3(+)) were studied. It was found that carbon impurity (0.7-0.8%) in hydrogen ion beam caused significant reduction 3 in the sputtering yield for Fe at elevated temperatures ( >= 773 K). On the other hand, the increase in the sputtering yield at elevated temperature was observed for F82H. Surface roughening at 423 K for Fe was pronounced in the case of C: 0.1%, but not in C: 0.7%. The mechanisms for these carbon effects could be related to surface disordering and change of grain orientation by mixed ion bombardment. (c) 2007 Elsevier B.V. All rights reserved.
