PROPERTIES OF FERROMAGNETIC MATERIALS INSIDE THE MATRIX OF ANODIZED ALUMINIUM COATINGS.
Abstract
Methods for imprgnating porous anodized aluminum coatings with magnetic substances and the basic behaviour of such complex structures were investigated. By use of electroless plating processes chemical reduction, and by thermal descomposition, taking place in situ, of metalorganic salts deposition inside the pores of metallic cobalt, iron, nickel, palladium and silver were achieved. These structures were studied with a torsion magnetometer, a vibration coercimeter, and a B-H electronic tracer. It was found that any type of metal or compound impregnating the pores was neither electrically conductive nor ferromagnetic, including samples heat treatmented 400 C for five hours. (Author)
