ジャーナル フリーBarrier anodic film formation on aluminum covered with a layer of hydrous oxide has been investigated by transmission electron microscopy of ultramicrotomed sections. Hydrous oxide film formed on aluminum by 5min reaction with boiling distilled water was found to consist of an inner dense layer of relatively uniform thickness, about 1100Å, and an outer fibrillar laver of varying thickness. During anodic oxidation, the inner dense layer of hydrous oxide film was found to be incorporated into the barrier oxide layer growing beneath the hydrous oxide film. Presence of γ'-crystalline layer containing voids and cracks was revealed clearly in the barrier oxide layer. The mode of the growth of γ'-crystalline layer within the barrier oxide was found to be consistent with the mechanism of the barrier anodic film formation on aluminum in the presence of hydrous oxide layer proposed by Alwitt.抄録全体を表示PDF形式でダウンロード (1728K) -

ジャーナル フリーAl-Si alloy castings AC3A were wet ground with a SiC type grinder at different work speeds and different depths of cut using various grinding fluids. Effects of grinding conditions and plastic deformation on the residual stress were examined. The plastic atrain in ground layers was measured by the moiré method. The maximum residual stress is intensified and the depth of tensile stressed part is increased as the depth of cut increases and the work speed accerelates. The moiré strain in the normal direction at 1mm in depth from the surface has a closed correlation with the maximum residual stress. The residual stress and plastic strain in the ground layer are moderated by using oil type grinding fluids rather than water soluble type fluids.抄録全体を表示PDF形式でダウンロード (782K) -

ジャーナル フリーA practical and economical process for reclamation of aluminum sludges and waste solutions generated in a factory anodizing process was succesfully developed on the basis of a fundamental study on producing zeolite and aluminum sulfate. Waste water is neutralized, agglutinated, scummed and reacted with waste acid to produce aluminum sulfate. Waste alkali is reacted with sodium silicate to produce zeolite and recovered alkali.抄録全体を表示PDF形式でダウンロード (1006K) -

ジャーナル フリーIn a work on Al/FeS2 secondary cells, aluminum alloy negative elctrodes were studied to improve the cell performance. Al-Sn and Al-Mg alloy electrodes were the most promising in charge-discharge characteristics of the cell. When a 5154 alloy electrode was used, high and low voltage plateaus lay at 1.7 and 1.1V respectively in the discharge curve. The discharge capacity was twice that of 99.99%Al electrode. The cyclic voltammetry and electrodepsition test showed smooth and adherent aluminum deposits on Al-Mg alloy. The alloy had an effect on the reduction of Al(III). The activation energy on the Al-Mg alloy was less than that on 99.99%Al. Two intermediates, Al(II) and Al(I), were produced in reduction of Al(III).抄録全体を表示PDF形式でダウンロード (735K) -

ジャーナル フリーDirect suspension electrolysis of alumina in CaCl2-BaCl2 molten salt was performed as a new process for aluminum production in which alumina was directly reduced with calcium generated through electrolysis of the molten salt. The current efficiency of aluminum production in the molten salt at 1223K increases with an increase of CaCl2 content up to 80%. It also increases with increases in alumina suspension concentration and cathode current density and with temperature rise up to 1223K. Produced aluminum grows spherically up to about 20mm in diameter in the upper part of the molten salt. The rate of alumina reduction in this process is well analysed in the viewpoint of consumption of calcium electrolytically generated in the molten salt.抄録全体を表示PDF形式でダウンロード (643K) -

ジャーナル フリーAlumina reducing behavior in continuous and batch type apparatuses of a new electrolysis process was kinetically estimated in which alumina suspends in a CaCl2-BaCl2 molten salt. Alumina particles in the continuous process having density greater than that of the molten salt are reduced during sinking in the salt. When the alumina particles adhere on produced aluminum, they are reduced in the early stage of sinking, intermediate stage of staying in which more aluminum adheres and final stage of floating successively. Alumina particles in the batch apparatus are reduced suspending in the molten salt agitating by inert gas bubbles. The alumina reduction is accerelated with condensation of Ca in the molten salt and with decreasing particle radius resulting in a decrease of the electrolysis cell height in the continuous process.抄録全体を表示PDF形式でダウンロード (514K) -
