Proses korosi terjadi bila logam bersentuhan langsung dengan air atau udara. Timah adalah ringan ketahanan dan konduktivitas yang sangat baik. Berdasarkan penelitian pengkorosian pada material juga dapat dilakukan metode Anodizing dimana semakin lama proses anodizing tinggi laju benda Aluminium. menyatakan dalam penelitiannya bahwa arus di tingkatkan dari 1 sampai 3 A/dm2 akan menurun, namun at...

Electrochemical impedance spectroscopy (EIS) is a versatile technique to characterize electrochemical systems satisfying causality, linearity and stationarity requirements. Odd Random Phase multisine EIS (ORP-EIS) can measure time-varying impedances for non-stationary processes. In this work, operando ORP-EIS introduced monitor the anodizing of aluminum, which nonlinear process, by superimposin...

In the automobile sector, pistons are anodized on crown, ring grooves, and also skirts to improve its wear resistance corrosion properties. this work, we have carried out crown anodizing along with skirt simultaneously study of samples. The surfaces three different processes such as soft anodizing, hard microarc oxidation (MAO) or well known plasma arc (PAO). All differ in their respective proc...

Anodizing process is largely performed on aluminum alloys to enhance corrosion and wear resistances. However, this can significantly reduce the fatigue resistance of depending alloy parameters. This paper deals with influence anodizing aeronautical 2618-T851. The anodic film has been characterized after each step using scanning electron microscopy (SEM). analysis showed that layer was crazed ju...

BACKGROUND Search for materials that may either replace titanium dental implants or constitute an alternative as a new dental implant material has been widely studied. As well, the search for optimum biocompatible metal surfaces remains crucial. So, the aim of this work is to develop an oxidized surface layer on tantalum using plasma electrolytic oxidation (PEO) similar to those existing on ora...

OBJECTIVES The aim of this study was to determine the antibacterial properties of silver-doped titanium surfaces prepared with a novel electrochemical anodizing process. MATERIAL AND METHODS Titanium samples were anodized with a pulsed process in a solution of silver nitrate and sodium thiosulphate at room temperature with stirring. Samples were processed with different electrolyte concentrat...

Porous aluminum oxide membranes with a complete and even covering of alumina nanowires were formed in a one-step anodization process in dilute phosphoric acid electrolyte. The anodizing conditions can be adjusted to start forming alumina wires that originate on the surface of the porous alumina layer at the triple junction points (the edges of the hexagonal inter-pore structure where three pore...
