摘要： PROBLEM TO BE SOLVED: To provide a corrosion resistant film producible inexpensively with good productivity, for coating the surface of a separator in a fuel cell to give an effect to maintain a low contact resistance over a long term, and to provide a separator using the corrosion resistant film. SOLUTION: The separator 10 includes the corrosion resistant film 2 formed by layering a corrosion resistant layer 21 and a conductive layer 22 composed of one or more noble metal elements selected from Au and Pt, on the surface of a base material 1 composed of metallic materials such as Ti, Al and stainless steel. In the corrosion resistant layer 21 formed of an alloy of one or more noble metal elements selected from Au and Pt and one or more non-noble metal elements selected from Nb, Ta, Zr and Hf, when the content of the non-noble metal elements is set to 50-90 atom%, the alloy becomes an amorphous alloy, and pin holes are hardly formed and exposure of the base material 1 is prevented even if film forming into a thin film is carried out by an ordinary sputtering method and the like. When this corrosion resistant layer 21 is equipped in a substrate, the conductive layer 22 on the surface can be formed into a thin film and cost can be lowered in the separator 10.

摘要： PROBLEM TO BE SOLVED: To improve plasma resistance by adjusting Si/Al atomic ratio of alumina ceramic intercrystalline domain to below the specified value. SOLUTION: The Si/Al atomic ratio of alumina ceramic intercrystalline domain is adjusted to below 0.2 and the width of the intercrystalline domain is preferably made less than 10 Angstroms. A silica glass phase existing in the intercrystalline domain is corroded by fluorine plasma having high chemical activity and subsequently the formed pit-shaped corrosion holes physically damage the alumina ceramic as the starting points. Therefore the improvement of the chemical corrosion property is indispensable for improving the fluorine plasma resistance of the alumina ceramic. It is necessary that the state of the silica glass phase existing in the intercrystalline domain is changed so that the phase is hardly volatile and corroded chemically even when irradiated by fluorine plasma. The Si/Al atomic ratio of the intercrystalline domain can be changed by adjusting the particle size, the purity, etc., of alumina powder of the raw material. When the Si/Al atomic ratio is low, the plasma resistance is improved. This sintered compact is obtained by sintering under a nitrogen atmosphere.

摘要： PROBLEM TO BE SOLVED: To maintain the anodic oxidation treatmentability, thermal cracking resis tance and corrosion resistance of anodically oxidized films at the same level as the level of a base metal by including the joint part for jointing a pair of Al or Al alloy base materials to each other by a plastic region formed by sliding of these base materials and a probe consisting of material harder than the base materials and the anodically oxidized films formed on the base materials and the joint part into the above member. SOLUTION: The joint part is formed by rotationally operating the probe consisting of the material harder than Al and using a friction agitation joining method forming the plastic region in the Al of the butt part of, for example, two plates. The temperature of the joint part does not rise up to a dissolution temperature at the time of joining and the joint part is joined by utilizing plastic deformation and, therefore, the crystal grain size of the joint part does not grow larger than the crystal grain size of the base metal. Accordingly, the texture of the joint part is approximate to the rolled structure and cast structure and, therefore, the anodically oxidized films having the excellent corrosion resistance may be formed. More preferably the ratio of the crystal grain size of the joint part and the crystal grain size of the base materials is
