    Oxidation in space

    “Oxidation in Space” will investigate how quickly metals oxidise in space.

    As oxidation of metal requires the presence of oxygen and water, the question is asked

    ”What is the rate of oxidation of different metals in space?"

    Oxidation will be measured by comparing;

    1. Changes in relative colour - measured by a colour-digitising camera with strobe.

    2. Changes in internal and external electrical conductivity [corrosion is a poor conductor].

    Different metals are to be tested for oxidation via atomic oxygen using changes in conductivity. Small strips of metal (e.g. thickness of aluminium foil ½ mm thick and 5-10 mm wide) to be used such as: cobalt, steel, stainless steel, copper, nickel, aluminium, gold, titanium (silver is not appropriate as it produces gases in a vacuum).

    Colour change is to be viewed by camera shots.

    Measuring conductivity is to detect surface change and if any physical changes are seen.

    Experimental sites:

    1. The Space Station external platform [unknown oxidation environment]

    2. The Pines School science classroom [low oxidation environment]

    3. The Pines School science classroom roof-top [moderate oxidation environment]

    4. Neptune Island weather recording station [extreme oxidation environment]
