Abstract

Studies have been made on the behaviour of copper-manganese alloys, with and without addition of other elements in synthetic sea water, using potentiostatic technique. It is found that 70:30:Cu:Mn alloy hassuperior corrosion resistance probably because of the homogeneous micro-structure of the alloy. Addition of misch metal further improves corrosion resistance. The corrosion rate values were found to decrease in the following order: 80120: CuIMn, copper, 70130: CuIMn and CuIMn misch metal. The anodic Tafel constant (b,) is found to be 75 * 5 mvldecade, for copper and its alloys. Addition of manganese to copper shifts the open circuit potential in cathodic direction. It also marginally increases the hardness.
