Abstract
The corrosion behaviour of copper in solutions of mono-, di- and trichloroacetic acids of different concentrations has been investigated. The maximum steady state potentials are achieved from the positive direction, indicating the destruction of the preformed oxide film on the electrode surface. An increase in the concentration of acid solution is accompanied by a marked shift of the potential in the positive direction. The maximum steady state potential is found to be related to the concentration of the acid solution by the equation E = a + b log c, where a and b constants. The rate of corrosion decreases with increasing solution concentration. The effect of temperature on the steady state potentials and the rates of corrosion of copper have also been investigated in 2M solutions of these acids. 28 ref.--AA.
