X-Ray Analysis Used to Predict Sulfur Corrosion Rates in Crude Oil

Industry and university researchers are using x-ray techniques to develop an analysis tool to more accurately predict how sulfur compounds in crude oil could corrode processing plant equipment.

Fungi Species Could Limit Concrete Corrosion by Healing Cracks

Researchers say the application of a specific species of fungi into the concrete matrix during the mixing process could serve as an unusual candidate to help concrete heal itself.

Study: North American Waterways Becoming Saltier, More Alkaline

University researchers find significant increases in both salinization and alkalinization of U.S. streams and rivers, which can influence the water's corrosivity.

Investigators Find Severe Corrosion in 2015 California Gas Leak

Independent investigators found extensive corrosion on the well casing that broke open at Southern California Gas Co.'s Aliso Canyon gas storage facility in October 2015. In the aftermath, engineering consultancy Blade Energy Partners was granted authority by the California Public Utilities Commission (CPUC) to conduct a root cause analysis of the metallurgical and fractographic aspects of the gas leak.

Thermal Imaging Used for Nondestructive Testing of Concrete Pillars

Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.

Geopolymer Solution for Sulfuric Acid Corrosion at Wastewater Plants

In a recently issued paper, Austrian researchers from TU Graz and the University of Graz discuss new materials that prevent damage from the microbiologically influenced corrosion of concrete.

Academic Study Seeks Policy Changes After Flint Water Crisis

University researchers issued findings on policy problems that led to the Flint water crisis and recommended legal changes to mitigate future concerns, including better communication on issues such as corrosion controls.

Researchers Tout Three-Dimensional Printing Breakthrough for Metal Alloys

Researchers with the Lawrence Livermore National Laboratory and several other groups achieved a breakthrough in the three-dimensional printing of Type 316L stainless steel alloy.

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.

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.

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.
