Corrosion of Iron-Chromium Alloys in Hot Concentrated Caustic Soda Solution

Pneumothorax following inhalation of caustic soda fumes.

new family home. He accidentally leant over the bucket and inhaled the fumes produced by the solution. Five minutes after the inhalation, he developed persistent pleuritic, right-sided chest pain and breathlessness. There was no personal or family history of pulmonary disease, and he had never smoked. Physical abnormalities were confined to the chest. He had a respiratory rate of 30 a minute an...

Corrosion mechanism of Ti-Cr alloys in solution containing fluoride.

OBJECTIVE The objective of this study was to clarify the influence of chromium content on surface reaction of Ti-Cr alloys in an acidic fluoride-containing saline solution. METHODS Four Ti-Cr alloys containing 5, 10, 15 or 20 mass% chromium were characterized in terms of dissolution of metals in an acidic fluoride-containing saline solution and surface structure by X-ray photoelectron spectro...

High-temperature Corrosion Behavior of Iron Aluminide Alloys and Coatings

A multi-year effort has been focused on optimizing the long-term oxidation performance of ingot-processed (IP) and oxide-dispersion strengthened (ODS) Fe3Al and iron aluminidebased coatings. Based on results from several composition iterations, a Hf-doped alloy (Fe28Al-2Cr-0.05at.%Hf) has been developed with significantly better high temperature oxidation resistance than other iron aluminides. ...

Corrosion Behavior of Solution- Annealed CoCrMo Medical Implant Alloys

Corrosion behavior of solution annealed high-carbon and low-carbon CoCrMo wrought alloy, commonly used in medical joint implants, was investigated. The surface passivation properties remained similar with and without the various solution anneal conditions, while the rate of corrosion was lower for solution annealed high-carbon CoCrMo. Corrosion was found to target phase boundaries and certain g...
