Corrosion of metallic materials is a natural process, and our study shows that even in an alkaline environment severe corrosion may occur on a carbon steel surface. While corrosion cannot be stopped it can be retarded. Many of the traditional anti-corrosion approaches such as the chromate process are effective but hazardous to the environment and human health. Mefp-1, a protein derived from blu...

This paper provides a review of the state of the art on the study of the fatigue behaviour of mechanical components coated with thin hard corrosion-resistant coatings such as the physically or chemically vapour deposited ones. Some references address the experimental characterization of the fatigue resistance of coated steel and light alloys. Some coatings have been observed to prove effective ...

Optical Coherence Tomography (OCT) is one of the most rapidly advancing techniques. This method is capable of non-contact and non-destructive investigation of the inner structure of a broad range of materials. Compared with other methods which belong to the NDE/NDT group (Non-Destructive Evaluation/Non-Destructive Testing methods), OCT is capable of a broad range of scattering material structur...

Abstract: This research examines the performance of strengthened non-uniformly corroded reinforced self-consolidating concrete (SCC) members. This paper focuses on three aspects of concrete including corrosion, concrete cover loss, and repair technique. Up to a 50% corrosion level is considered in this study. Corrosion was experimentally induced and was simulated in other cases. Twenty-six rein...

in this study, we have investigated the effects of mix of tomato (solanum lycopersicum) & carrot) daucus carota ( and red bell pepper )capsicum annuum( as a natural pigment source and astaxanthin as synthetic pigment sources on the skin colour of cichlid fish (astronotus ocellatus sp., agassiz, 1831), which are generally white with red patches in the dorsal skin. the fish were fed diets con...

The stability of an electrodeposited nanocrystalline Ni-based alloy coating in a H₂S/CO₂ environment was investigated by electrochemical measurements, weight loss method, and surface characterization. The results showed that both the cathodic and anodic processes of the Ni-based alloy coating were simultaneously suppressed, displaying a dramatic decrease of the corrosion current density. The co...

Waterborne epoxy resin (WEP) has been widely used as an anti-corrosive coating for metals. However, it is still a big challenge to further improve its anti-corrosion performance due the poor barrier properties corrosive media. In this study, fluorinated graphene (FG) was filler in WEP properties, which contributes corrosion resistance enhancement. The chemical composition and microstructures of...

y-tial intermetallic alloy have a good potential for use as biomaterial, due to its good corrosion resistance. in this paper, two fundamental electrochemical techniques namely electrochemical impedance spectroscopy and potentiodynamic anodic polarization were used to evaluate the corrosion performance of g-tial in ringer's solution. surface modification treatments were employed with the pu...

A mini-flowloop was developed to study CO2 corrosion and corrosion/erosion interactions, and to assess the effectiveness of inhibitors under conditions that simulate multi-phase pipelines. The miniflowloop was used to study the effect of testing time, steel chemistry, velocity, temperature, fluid chemistry, sand and inhibitors on corrosion rates. The measured corrosion rates in inhibited and un...
