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.
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.
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.
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.
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.
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.
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.
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.
Using nanobiotechnology and a process known as solid-state fermentation, university researchers are making concrete that regenerates to repair cracks as they develop.
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.
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.
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.
Although corrosion is a common problem coal in mines, as are material failures, there has been limited documentation of these issues in the literature or at conferences.
Funded by the European Commission, this new project involves the design of a portable, three-dimensional ultrasonic scanner for the nondestructive testing and evaluation of concrete in bridges and other building structures.
Highlights of the study include data on pipe material break rates; the analysis of age and corrosion in failure modes; observations on pressure, delivery demands, and the effects of soil corrosivity; and new metrics for pipe replacement rates.
