The paper presents the results of moisture detection in the depot and galleries of the Aeronautical Museum in Belgrade. The moisture and changeable temperature conditions are the main causes for corrosion in historical buildings and museum artefacts. The main purpose of the tests was to determine these conditions in the museum where very important metal artefacts are exhibited and deposed, including the only surviving example of the Fiat G50 aircraft, by applying passive IR thermography. The advantages of thermography in a rapid and accurate detection of moisture in the walls, ceilings and floors of the museum are analysed. Active IR thermography is used for the determination of the composite structure and the characterisation of hidden corrosion in some parts of the Fiat G50 aircraft. The recorded thermograms indicate the damage due to corrosion in many parts examined in detail by radiography and the XRD method.
Key words: thermography, IR thermography, moisture, corrosion, testing, museum, museum exhibits.
