In this paper, we study the corrosion behavior of parylene-metalparylene thin films using accelerated-lifetime soak tests. The samples under test are thin film resistors with a 200 nm layer of Au sandwiched by parylene-C on both sides, fabricated with parylenemetal skin technology. The samples are tested in hot saline both passively and actively, and different failure modes are observed using o...

We investigated the galvanic corrosion behavior of aluminum alloy in contact with carbon steel during accelerated testing by evaluating current and morphology coupled specimen. Electrochemical polarization curve was acquired before after testing, only detected for dissolution. Aluminum next to more severely corroded than remote aluminum. Corrosion also observed steel, although its dissolution n...

Concrete carbonation damages the passive film that surrounds reinforcement bars, resulting in their exposure to corrosion. Studies on the prediction of concrete carbonation are thus of great significance. The repair of pre-built reinforced concrete (RC) structures by methods such as remodeling was recently introduced. While many studies have been conducted on the progress of carbonation in newl...

We report a unique and highly stable electrocatalyst-platinum (Pt) supported on titanium-ruthenium oxide (TRO)-for hydrogen fuel cell vehicles. The Pt/TRO electrocatalyst was exposed to stringent accelerated test protocols designed to induce degradation and failure mechanisms identical to those seen during extended normal operation of a fuel cell automobile-namely, support corrosion during vehi...

In the realm of industrial automation, corrosion represents one primary modes failure, especially in case armored thermocouples exposed to temperatures ranging between 1073.15–1373.15 K. this context, selection metal materials that can withstand high-temperature oxidation and is paramount importance. Typically, resistance a given material assessed by measuring “annual rate” or “corrosion depth”...

Efforts to develop metallic zinc for biodegradable implants have significantly advanced following an earlier focus on magnesium (Mg) and iron (Fe). Mg and Fe base alloys experience an accelerated corrosion rate and harmful corrosion products, respectively. The corrosion rate of pure Zn, however, may need to be modified from its reported ~20 μm/year penetration rate, depending upon the intended ...
