The effects of surface pretreatment on the rate of scribe-creep caused by underpaint corrosion on coated AA2024-T3 (UNS A92024) were investigated. Scribe-creep experiments were conducted on epoxy polyamide-coated (average coating thickness: ~10 μm) AA2024-T3 in 80% relative humidity at 25°C, 40°C, and 50°C. Scribe-creep was observed to be enhanced by exposure test temperature regardless of surf...

In this work, the effects of tropical marine atmospheric environment on corrosion behaviour 7B04-T74 aluminium alloy were systematically investigated by using accelerated testing, together with kinetic analysis, microstructure observation, product composition and potentiodynamic polarization curve tests. The weight loss method was used for kinetics analysis. surface morphology products transfor...

The authors have reviewed flow-accelerated corrosion (FAC) programs used at various types of conventional fossil plants. The results and findings of the assessments are presented and discussed. A number of emergent areas of FAC damage have been added to the previous suite of recognized susceptible locations with a concentration on damage due to two-phase FAC. Several deficiencies related to fee...

Corrosion of Fe–25Ni–15Cr under the combined effects marine atmospheric exposure and subsequent high-temperature oxidation was investigated in present work. The results indicated that rate superalloy following field significantly accelerated due to deposited salts corrosion products. kinetic process clearly divided into two stages, resulting changes morphology, structure composition oxide film....

Abstract Corrosion and breakages of shielding layers are one the factors for degradation extruded three‐layer (E‐E type) 6.6 kV cross‐linked polyethylene (XLPE) cables. Tohoku Electric Power Network has been measuring electrical resistances in E‐E type XLPE cables, recently found layers. The authors performed an accelerated test cables by taking account aqueous solution, temperature, heat cycle...

PURPOSE Subglottic stenosis can result from endotracheal tube injury. The mechanism by which this occurs, however, is not well understood. The purpose of this study was to examine the role of angiogenesis, hypoxia and ischemia in subglottic mucosal injury following endotracheal intubation. METHODS Six Yorkshire piglets were randomized to either a control group (N=3, ventilated through larynge...

This study provides a semi-probabilistic approach to durability design of reinforced concrete structures, subjected carbonation-induced corrosion. The method was developed from an existing and using comprehensive data collated the literature. A statistical model for predicting accelerated carbonation coefficient, as input variables mix proportions test conditions also generated. performance pro...
