Abstract: A magnesium alloy material with excellent corrosion resistance is provided. The magnesium alloy material comprises a magnesium alloy containing 7.3%-16 % by mass Al. When the Al content for the whole magnesium alloy material is x% by mass, the area with an Al content of 0.8x%-1.2x% by mass is 50% by area or more, the area with an Al content of 1.4x% by mass min. is 17.5% by area max., and there is substantially no area with an Al content of 4.2% by mass max. This magnesium alloy material can effectively prevent the occurrence of localized corrosion and the progression of said corrosion, as a result of the low variation in Al concentration and the lack of areas with extremely low Al content. Accordingly, the magnesium alloy material has excellent corrosion resistance compared to a die cast material with the same overall Al content. The magnesium alloy material can be used for plate material, coil material comprising rolled long plate material, and formed articles.

Abstract: [Object] To provide a gas decomposition apparatus and a gas decomposition method in which no safety problems occur in spite of the application of a relatively high voltage between an anode and a cathode for the purpose of decomposing odorous gases of many types. [Solution] A catalytic electrode layer 6 that contains a catalyst and is porous; a counter electrode layer 7 that forms a pair with the catalytic electrode; and an electrolyte layer 15 that is sandwiched between the catalytic electrode and the counter electrode and has ion conductivity are included. The catalyst is held by the catalytic electrode in the form of being carried by a carrier containing a conductive material or the catalyst is directly carried by the catalytic electrode. A conductive material in the catalytic electrode, the conductive material being in contact with the catalyst, is not a noncovalent carbon material.

Abstract: membro estrutural de uma liga de magnésio. é fornecido um membro estrutural de uma liga de magnésio possuindo excelente resistência à corrosão. o membro estrutural de uma liga de magnésio inclui um substrato de liga de magnésio que contém mais do que 7,5% em peso de al e uma camada anticorrosiva formada em um superfície do substrato pelo tratamento de conversão química. o substrato contém um precipitado, tipicamente, partículas dispersas no mesmo. as partículas são feitas de um composto intermetálico contendo pelo menos um de al e mg e têm um tamanho médio de partícula de 0,05 m ou mais e 1 m ou menos. a área total das partículas representa entre 1% da área ou mais e 20% da área ou menos. a camada anticorrosiva inclui uma subcamada inferior e uma subcamada de superfície no substrato nesta ordem. a subcamada de superfície é mais densa do que a subcamada inferior. o substrato do membro estrutural de uma liga de magnésio tem alta resistência à corrosão por causa de um alto teor de al. o membro estrutural de uma liga de magnésio tem excelente resistência à corrosão por causa da subcamada densa no lado frontal da camada anticorrosiva, que impede que um líquido corrosivo atinja o substrato. a subcamada inferior porosa pode reduzir a tendência da camada anticorrosiva de separar do substrato, por exemplo, quando de um impacto e permite que o membro estrutural de uma liga de magnésio possa conservar uma alta resistência à corrosão.

Abstract: A magnesium alloy material having high corrosion resistance is provided. The magnesium alloy material contains a magnesium alloy containing 7.3% to 16% by mass Al, wherein a region having an Al content of 0.8x% by mass or more and 1.2x% by mass or less occupies 50% by area or more, a region having an Al content of 1.4x% by mass or more occupies 17.5% by area or less, wherein x% by mass denotes the Al content of the entire magnesium alloy material, and there is substantially no region having an Al content of 4.2% by mass or less. The magnesium alloy material has small variations in Al concentration and includes a few regions having a very low Al content, thereby effectively preventing and retarding local corrosion. Thus, the magnesium alloy material has higher corrosion resistance than die-cast components having the same Al content. The magnesium alloy material may be a sheet, a coiled long sheet, or a formed product.
