    Résumé indiqué en début d'article : 
    
    "In 1984 the Australian War Memorial (AWM), Royal Australian Air Force and Royal Australian Navy recovered a crashed Japanese Army Air Force Nakajima Ki 43 II "Oscar" fighter aircraft from Papua New Guinea. The aircraft had crashed at the end of an airfield and had been sitting in swampy ground since 1944, and had subsequently corroded and suffered extensive deterioration. In 1996 electrolytic treatment development for corroded composite metal artifacts had reached the stage where it was feasible to electrochemically treat "Oscar " without needing to breakdown the aircraft into small separate components. An above ground swimming pool was erected and filled with a solution of citric acid, sodium hydroxide and water. An electrolytic cell was formed by using expanded stainless steel mesh as anodes and making the aircraft the cathode. An applied potential of approximately 1.15 volts, (with respect to a mercury sulphate electrode) was administered for one month. Electrolysis was followed by a further polarization in fresh water for one week to remove the chemicals. Upon removal from the pool the aircraft was cosmetically treated to remove flash rust and finally coated with wax. During the treatment samples were taken from the pool to monitor pH and concentrations of dissolved chloride, iron, copper and aluminium."
