Copper atmospheric corrosion in tropical climate

Copper sample were exposed (for 1 year) in different areas of Fuerteventura Island from Canare Archipelago, to study atmospheric corrosion in this tro pical climate. The chlorine and SO2 concentrations were determined; also th e moisture content was measured all exposure time. The corrosion products w ere analysed by X ray diffraction. The copper corrosion rates in this clima te are very high and exceed the values of the current standards for atmosph eric aggressivity; so it is necessary to be added a new atmospheric corrosi on grade.
