EFFECTS OF TEMPERATURE ON THE CORROSION OF COPPER IN SEA WATER AT DIFFERENT HYDROSTATIC PRESSURES.

An investigation has been made of the effect which an increasing hydrostatic pressure may have on copper corrosion at different temperatures in sea water at pH 7. 8. The tests were carried out at a pressure of 1, 50, 100, 200 and 300 atm at a temperature of 5 degree , 10 degree and 20 degree C. It was found that copper corrosion is always stimulated by a pressure rise and that the increased corrosion rate is accelerated by increasing temperatures.
