Analysis Cites Flawed Management in Oroville Dam Failures

Researchers investigated corrosion-related failures of the Oroville Dam Gated Spillway in California, concluding that inappropriate standards, guidelines, procedures, and processes were used in its evaluations.

U.K. Grant Targets Sensors for Corrosion Protection in Heating, Cooling Units

A collaborative project funded partly by the U.K. government is looking to develop cost-effective sensors capable of measuring the corrosion rates of metals used in water-based heating and cooling units.

Failure of Water Wall Tubes Caused by Hydrogen Embrittlement from Severe Underdeposit Corrosion

In a CORROSION 2017 paper, authors discussed two water wall tubes in a multistage flash distillation plant’s operating boiler that experienced failure after 14 years of service.

New Technique Tracks Water in Concrete via Electrical Imaging

Researchers at North Carolina State University and the University of Eastern Finland are working on a novel technique for tracking water in concrete through the use of electricity.

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.

Testing for Microbiologically Influenced Corrosion in Humid Air

Researchers with the Southwest Research Institute conducted experiments to evaluate the presence of microbiologically influenced corrosion under high and low relative humidity conditions when storing spent nuclear fuel in dry storage systems.

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.

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.

Test Samples of Reinforced Concrete Are Often Too Small

A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.

Roundtable on the Future of Corrosion Control: Part 2

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. For Part 2 of this series, the featured panelist is Fred Goodwin, head of BASF Construction Chemicals Global Corrosion Competency Center.

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.

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.
