University Develops Adjustable Atmospheric Corrosion Test Rack

The design of the modular corrosion test rack by University of Alaska Anchorage researchers allows it to be adjusted to three different exposure angles. This rack helps isolate corrosion-inducing variables in cold climates and their primary effects on corrosion.

Corrosion Damage Repairs to the Arvida Aluminum Bridge

During its first 34 years in service, Canada’s Arvida Aluminum Bridge sustained some corrosion damage that required work. After a further ~30 years in service, the bridge was inspected to determine the effectiveness and longevity of that repair work. This article describes the corrosion damage, the repair work, and the current condition of the bridge.

Testing Corrosion-Resistant Alloys for Use in Geothermal Power Plants

Utilizing the energy potential in high-power geothermal wells can be expanded with materials that withstand the extreme environmental conditions.

The Humble Building Material that Shelters Millions Across the Globe

Corrugated iron has been and continues to be an invaluable building material that deserves to be taken seriously. It shows that steel can be simply and cheaply formed to a useful shape, protected from corrosion by a range of coatings, and made accessible to citizens in all corners of the globe.

Roundtable on the Future of Corrosion Control: Part 3

In the final part of this series, three industry panelists share their predictions on where the corrosion industry is going in the next 25 years and beyond.

Investigators: Design Issues Behind Florida Bridge Collapse

A preliminary U.S. report determined that errors were made in the design of the pedestrian bridge’s main span, where two truss members were connected to the deck.

Fabrication Practices to Mitigate Risks of Refinery Corrosion Cracking

Industry engineering experts describe several cracking-related damage mechanisms and discuss control measures to mitigate corrosion and cracking in refinery units.

Control of Environmental Degradation of Concrete Power Poles

Since significant funds are expended for replacement, an investigation was launched into the effects of mechanical activity and corrosion in the degradation of the concrete poles.

Protecting Concrete Cooling Towers from Corrosion

When exposed to harsh operating environments, reinforced concrete cooling towers can develop severe corrosion of embedded steel reinforcement that leads to concrete delamination and spalling

Automotive Study Eyes Corrosion of Body Panels, Underbody Parts

After examining the rust patterns on hundreds of vehicles, researchers say untreated vehicles had nearly seven times more visible corrosion on body panels than on vehicles protected with rust control treatments.

Self-Healing Material Builds Itself from Carbon Exposure

The polymer, which might someday be used as construction or repair material or for protective coatings, continuously converts the greenhouse gas into a carbon-based material that reinforces itself, according to the researchers. This “self-healing material,” designed to mimic the absorption properties of green plants, has potential applications in a variety of construction and protective coatings projects.

Phased Array Ultrasonic Testing Detects Steel Bridge Corrosion

Minnesota transportation officials say using phased array ultrasonic testing with three-dimensional scanning more accurately detects and measures corrosion on steel bridges than traditional methods.

Roundtable on the Future of Corrosion Control: Part 1

Industry panelists share their predictions on where the corrosion industry is going in the next 25 years and beyond by predicting the corrosion control developments of the future.

Tank Integrity Studied at Radioactive U.S. Waste Storage Site

In the latest round of testing, investigators found that two tanks at the decommissioned Hanford nuclear production complex in Washington had spots showing significant thinning in a ring around the shell’s wall.

New Sensing, Simulation Tools Predict Military Aircraft Corrosion

The Air Force Research Laboratory says it is developing a new environmental sensing platform and testing chamber apparatus to enable superior management of aircraft corrosion. Researchers are currently testing both devices, which they believe could help preemptively predict corrosive environmental conditions before they can cause damage to military assets.
