Abstract Anodizing refers to conversion coating of the surface of aluminum and its alloys to porous aluminum oxide. This article provides the reasons for performing anodizing and discusses the three principal types of anodizing processes, namely, chromic acid process, sulfuric acid process, and hard anodic process.

Anodization of molybdenum. I. Galvanostatic anodization
Journal of Applied Electrochemistry, 1987Molybdenum was anodized at different current densities (10−4–10−2 A cm−2) in various aqueous solutions. Potential-time curves obtained in strong acid solutions are similar to those usually reported for the valve metals, and the anodization kinetics were found to obey the familiar exponential law $$i = A \exp BH$$ and also to obey the empirical ...

Nanoporous Anodic Bismuth Oxide Photo-Anodes
ECS Meeting Abstracts, 2014Metal-oxide semiconductors have received a wide attention as photo anodes since the demonstration of water splitting by TiO2 electrode under UV illumination [1]. Significant research efforts were focused on developing various semiconductors with band-gap engineering for efficient photo water splitting.

Abstract Anodizing produces a uniform, continuous, highly ordered network of individual cells comprising a layer whose thickness and cell dimensions, and ultimately engineering properties, depend on the electrochemical parameters of the anodizing process.

Fabrication of porous anodic alumina using normal anodization and pulse anodization
AIP Conference Proceedings, 2015This article reports on the fabrication of porous anodic alumina (PAA) by two-step anodizing the low purity commercial aluminum sheets at room temperature. Different variations of the second-step anodization were conducted: normal anodization (NA) with direct current potential difference; pulse anodization (PA) alternate between potential differences ...

Proceedings of the IRE, 1935
The anode direct current versus grid bias voltage characteristic of tubes is developed in a sum i = ZAneaV, where two or three terms suffice to represent the curves of some modern commercial tubes quite accurately. This development has two practical advantages.

Anode spot vacuum arc model: graphite anode
IEEE Transactions on Components and Packaging Technologies, 2000A model of near anode processes in vacuum arc anode spots on graphite electrode is developed. The physical model is based on a kinetic treatment of anode evaporation and plasma production. The system of equations formulated in the paper includes description of plasma flow in the kinetic and in the plasma acceleration regions in a self-consistent manner.
