| Abstract(in English) | Palladium is one of the most useful and important materials for low load contacts because of its good propert,against corrosive gases.In this study,influence of atmospheric pressure and humidity on palladium oxide formation caused by mechanochemical reaction which might deteriorate the contact reliability was investigated, and the conditions of the appearance of this phenomenon were determined.It was found that palladium oxide was not formed in the atmospheric pressure lower than a threshold level,which became lower in lower humidity.Aqueous vapour was thought to have an effect to restrain the palladium oxide formation,and an explanatory model for this restraint mechanism was proposed.The proposed model was verified through experiments in purified air where neither aqueous vapour nor organic vapour had any influence. |
