A factory produces both aluminium alloy heat exchangers and copper + brass heat exchangers. As a result, a small deposit of copper is formed on a relatively large aluminium alloy aircraft heat exchanger. This heat exchanger is then subject to saltwater spray, from operating at a coastal airport. What effect will the deposit have? What impacts the severity of this effect? What action could you take to prevent this kind of problem from occurring in future?
