Topics in Number 46 include:Comprehensive review of the structural aspects and anti-corrosion properties of passive films on metals and alloys; a detailed description is given of the nucleation and growth of 2-dimensional passive films at earlier stages, their effect on the corrosion properties of metal surfaces, and the nanostructures of 3-dimensional passive filmsResearch on nano-and micro-fabrications based on anodizing treatments combined with chemical/mechanical processes such as laser irradiation, atomic force micro-probe processing, and thin film deposition techniquesPassivity of aluminum-based amorphous alloys and stainless steels and the catalytic activity of copper-based amorphous alloysTheoretical analysis of the admittance behavior of passive film/electrolyte junction based on the theory of amorphous semiconductor Schottky barriers
