Because of the existence of corrosion media such as chlorine, serious corrosion attacks ships, offshore and marine structure. Scholars worldwide have been long committed to the research of marine corrosion and development of anti-corrosion agents, and have achieved remarkable results. But so far, the conventional ocean coating inevitably makes microholes or microcracks between the additive and ...

chromate conversion coating is applied on aluminum 6061. the optimum conditions for chromate bath composition and immersion time are also obtained for standard requirements provision such as corrosion resistance in salt spray test, electrical resistance and coating quality. the applied coatings are electrochemically tested in sea and distilled water. according to tafel and cyclic polarization c...

Zinc-Nickel electrodeposits have been widely adopted for surface treatment of automobile steel sheet for high corrosion resistance. In this work the effect of pulse parameters on the Zn-Ni alloy electrodeposits was investigated. The hardness, thickness, corrosion resistance and composition of deposits thus produced were investigated. The surface topography of the deposits was also observed in S...

Microstructural inhomogeneity generally deteriorates the corrosion resistance of materials due to the galvanic effect and interfacial issues. However, the situation may change for nanostructured materials. This article reports our studies on the corrosion behavior of SiC nanoparticle-reinforced Al6061 matrix composite. It was observed that the corrosion resistance of Al6061 increased when SiC n...

Corrosion of steel reinforcement in concrete is generally considered as an electrochemical process which reduces the service life of a structure exposed to chloride ions attack. Therefore, laboratory experiments were performed in order to ascertain the effectiveness and sustainability of ternary inhibitors (calcium nitrite, ethanolamine and eco-friendly green Bambusa Arundinacea) in protecting ...

in this study, plasma electrolytic oxidation of 2024-t3 aluminum alloy was investigated. the electrolyte used in this investigation was an alkaline solution containing additives of silicate, phosphate, potassium hydroxide and glycerin. a conventional dc power source with a low applied voltage was employed. corrosion resistance of the oxide layer was investigated by means of tafel plots and elec...

Copper alloys are widely used in the manufacturing of heat transfer applications, this due to their excellent heat transfer properties. Copper contamination is one of the serious industrial problems in the boiler feed water system. This contamination commonly resulted from copper corrosion reactions in boiler feed water environment. The best way to reduce the copper contamination is by improvin...

Ti-based bulk metallic glasses (BMGs) are very attractive for applications because of their excellent properties such as high specific strength and high corrosion resistance. In this paper, we briefly review the current status of the research and development of Ti-based bulk metallic glasses. Emphasis is laid on glass-forming ability, mechanical properties, corrosion resistance, and biocompatib...

Corrosion resistance, wear resistance and biocompatibility of the studied Ti–Ta alloys with Ta contents of 10, 30 and 70 mass% together with the currently used metallic biomaterials pure titanium (Ti) and Ti–6Al–4V extra low interstitial (ELI) alloy were investigated for biomedical applications. Corrosion resistance was measured by an anodic polarization test using an automatic potentiostat in ...
