Abstract: Molybdenum based alloys, such as TZM, Z6 and Mo-41Re, have been considered as possible divertor cooling-channel materials for NET. Preliminary corrosion investigation of these alloys and pure molybdenum in water with variable pH values from 2.9 to 11.1 has been carried out at 95-degrees-C. In this paper we present first results obtained from anodic potentiodynamic polarization measurements of molybdenum and its alloys, and from bimetallic corrosion experiments in which molybdenum base materials TZM and Z6 have been coupled with 316L stainless steel. The results indicate that the electrochemical corrosion potential of the molybdenum based alloys increases with decreasing pH value, and the coupling of type 316L stainless steel to the molybdenum alloys leads, depending upon the pH value, either to cathodic protection or to accelerated corrosion of the molybdenum alloys.
