The Sintering Mechanism of Aluminium and the Anodization of Aluminium Sintered Bodies

[摘要] It has been said that aluminium is hard to sinter. This is because a hard aluminium oxide film forms naturally onexposed aluminium in air, and in the case of heat-treatment for sintering, another type of hard aluminium oxidefile also forms. Thus aluminium is hard to sinter at about 600℃. The uthor has succeeded in manufacturingaluminium sintered bodies, by using a vacuum, an inactive gas or a reducible gas atmosphere for the sinteringenvironment.The possibility of producing a satisfactory dielectric on the aluminium sintered body was also investigated. Analuminium sintered body has physical properties different from aluminium foil or plate, because it is always in theporous state.In this paper, the author presents the experimental results on aluminium sintered bodies manufactured undervarious conditions and the results of anodization of the sintered bodies.
