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.

Real-time Structural Health Monitoring to Detect Cracks

U.S. and U.K. researchers are working together on the development of real-time sensing systems to alert maintenance engineers of cracks in transportation infrastructure.

The Science Behind It: Fracture Investigation of a S13Cr-110 Tubing String with Premium Joints

An investigation and testing on a fractured premium joint tubing string in a high-pressure, high-temperature well determined the failures were caused by stress corrosion cracking.

Underdeposit Corrosion in a Subsea Water Injection Pipeline

Underdeposit corrosion (UDC), a general term that refers to localized corrosion that develops beneath or around deposits on a metal surface, is a phenomenon that leads to pipeline failures and is one of the most damaging forms of corrosion for oil and gas pipelines. It can occur in subsea water injection pipelines, well-fluid pipelines, and large-diameter transmission lines.

New Bacterial Process Developed to Heal Concrete

Using nanobiotechnology and a process known as solid-state fermentation, university researchers are making concrete that regenerates to repair cracks as they develop.

Iridium—The Ultimate in Corrosion Resistance

Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.

Advanced Corrosion, Rust Drive Brake Pad Failures

A new study from the Global Brake Safety Council suggests the use of substandard materials and processes in automobile brake pads could be leading to accelerated failure modes. The council was formed in 2014 to advocate and raise awareness for high standards in brake safety while ensuring responsible manufacturing in the automotive industry.

Crawling Robot System to Detect Corrosion Under Insulation

Case studies were recently conducted to test the ability of a robotic system to potentially perform corrosion under insulation (CUI) inspections in oil, gas, and petrochemical environments.

Researchers Suggest New Method to Create Corrosion-Resistant Alloys

A new study suggests that a better protective oxide scale can be achieved in high-temperature Al alloys by controlling the size distribution of reactive element particles. These types of alloys are prevalent in many industrial sectors and applications.
