In order to stay on top of the latest industry news, we’re always scouring the web for articles on corrosion, composites and pipe supports. Here are some articles that caught our attention in September.
Thermodynamic explanation of the universal correlation between oxygen evolution activity and corrosion of oxide catalysts
This paper used thermodynamic principals to prove that any metal oxide will become unstable (read: corrode) under oxygen evolution conditions due to the oxygen anion instability in the metal oxide lattice. The authors keyed the term “Lattice Oxygen Evolution Reaction” (LOER). Although the authors’ motivation for this study was energy conversion devices for renewable energy applications, metal and oxygen are everywhere so this paper has many relevant takeaways for all of us. Make sure to brush up on your basic corrosion knowledge before diving into this paper!
Advances in Modeling of Solidification Microstructures
Metallic fabrication processes, such as welding, introduce a variety of microstructures to the fabricated metal which can affect its material properties. This article discussed the impressive strides that have been made in computation simulation that will allow for more accurate predictive models of metallic microstructures.
Pipeline Stress Corrosion Cracking: Detection and Control
NACE interviewed three corrosion experts (John Beavers, Fraser King, and Sergei Shipilov) about stress corrosion cracking (SCC) of underground natural gas and liquid petroleum pipelines. The panelists discussed why SCC occurs on pipelines, the associated risks, and assessing SCC susceptibility of pipelines to SCC.
Wineries: Equipment, Materials, and Corrosion
Like the energy industry, the wine industry is not immune to corrosion! Sulfur dioxide (SO2), which is found in wine, is highly corrosive, yet very useful in wine making. SO2 is an antiseptic, protects wine from oxygen damage, and also prevents browning of the wine. This article discussed the various materials utilized by the wine industry to prevent corrosion.
Ultralight composite scooter for sustainable urban mobility
This article discussed a new solar-powered scooter designed in a joint project between BASF and Floatility. The scooter, intended for “urban mobility”, is designed to be extremely lightweight so the user can carry it when not in use. A composite material (mineral-filled polyamide resin with fiberglass reinforcement) was chosen for the scooter’s body and deck due to its lightweight, yet high strength properties. Lightweight AND high strength? Sounds like great properties for your pipe supports!
