This work aims at investigating the effect of tannin, a natural compound, as corrosion inhibitor for bare and coated aluminum alloys (AA1200). Tannin was characterized by Attenuated Total Reflectance Fourier Transform ...

Biobased polyurethane coatings derived from vegetable oils, with 2 different compositions, were prepared and applied on the AA1200 aluminum alloy to confer corrosion protection. The influence of the ratio between the ...

The investigation combines microstructura l characterization analyses and atomistic modeling to elucidate the mechanism of carburization embrittlement of an iron-nickel-chromium alloy expo sed to high temperature. It was ...

Zinc and tin, together with Zn-Sn alloys are used in industrial operations and steel coatings against corrosion. One of its most common uses is the galvanizing process for outdoor structures, which is affected by corrosion ...

A common phenomenon in the dissimilar joints is the presence of brittle compounds in the joining interface region. The brittle phases can decrease by introduction of interlayers in the joining interface, such as silicon, ...

Machining processes are one of the most important manufacturing processes in the modern world. In these processes, there are many elements which will influence in the final result of the machined part. Among them, the tools ...

Nesse trabalho realizou-se a caracterização por espectroscopia de infravermelho com Transformada de Fourier (FT-IR) e ATR e o estudo eletroquímico e de corrosão de filmes orgânicos aplicados sobre ligas de alumínio AA1200 ...

Several alloys have been used for prosthodontics restorations in the last years. These alloys have a number of metals that include gold, palladium, silver, nickel, cobalt, chromium and titanium and they are used in oral ...

Ti-6Al-4V alloy with TiO2 coating is the most commonly selected material to construct an aortic heart valve. Wear resistance is the main mechanical property to be evaluated for this purpose. In this paper, the wear resistance ...
