Abstract
Metal anodizing process is now widely applied to not only usual commercial products but also advanced materials like a photo-catalyst or some nano-materials. In these applications, micro-pore or nano-pore structure in the anodized oxide film, e.g. pore arrangement or straightness, is considered to be important to improve the performance of electric devices etc. In this research, in order to obtain good arrangement and straightness and control of pore size, strong magnetic field and strong electric field imposition during anodization are conducted for Al and Ti under intense electric field and intense magnetic field imposition. Strong electric field can control the pore size and its distribution. Strong magnetic field can promote the metal substitution reaction and it also increase the metal anodizing. Furthermore, magnetic field has the possibility of ordering the pore arrangement in the anodized film.
