dc.description.abstractCorrosion behaviour of Ti25-0.5xV40Cr35-0.5xRhx (x= 0, 0.5, 1 at %) alloy electrode in 6M KOH was investigated. The V-rich alloy was produced under argon atmosphere in an open hearth crucible furnace. The microstructure of the arc-melted alloy was examined by scanning electron microscopy, and the phases were identified by X-ray diffraction. The as-cast alloys contained a primary (V) body centered cubic phase and an intergranular αTi phase. Rhodium (Rh) decreased the Ecorr from -767 mV to -793 mV for 0.05 Rh and -825 mV for 0.10 Rh. The corrosion current also decreased from 1 μA/cm2 in Rh-free alloy to 0.77 μA/cm2 with addition of 0.05 at % Rh and 0.37 μA/cm2 with addition of 0.10 at.% Rh. Addition of 0.05 at. % Rh decreased the corrosion rate from 0.0110 to 0.0009 mm/y and to 0.001 mm/y with addition of 0.10 at.% Rh. Hardness of the alloy electrode decreased with addition of rhodium.en_US
