New Metal Corrosion Sensor Designed for Printed Circuit Boards

Mitsubishi Electric has developed what it believes to be the world’s first compact metal corrosion sensor small enough to be mounted on printed circuit boards. The new sensor utilizes corrosion monitoring technology to detect the degree of corrosion of metal components caused by corrosive gases in the atmosphere.

Novel Phosphonate Proves Useful in Geothermal Environments

The researchers conclude that the novel phosphonate chemistry is useful in ultrahigh geothermal applications. Its high tolerance to calcium, biodegradability, thermal stability, and good performance against calcium carbonate scaling prove valuable in many environments.

Chemical Safety Board: Thermal Fatigue Led to Gas Plant Blast

In their final report, U.S. investigators say thermal fatigue in a heat exchanger likely caused a major hydrocarbons release in June 2016. This resulted in a series of fires and explosions at the Enterprise Products gas plant in Pascagoula, Mississippi.

Internal Corrosion Protection Strategies for Aboveground Storage Tanks

In a CORROSION 2019 conference paper, the authors analyzed two case studies of corrosion-prone tanks using dissimilar metals and the challenges that arose in providing them with adequate cathodic protection (CP).

The U.S. Navy has developed a new corrosion/anomaly detection sensor payload and processing scheme, outfitted to a commercial unmanned aerial vehicle, to help inspect for material defects, corrosion, warping, and more.

U.S. Navy Adopts Composite-Patch Repair Method for Aluminum

Engineers at the U.S. Naval Surface Warfare Center are now utilizing a new composite-patch repair method for incidents involving stress corrosion cracking on aluminum substrates.

Corrosion-Resistant Alloys in Downhole Applications

The authors discuss different material selection procedures, case histories of corrosion, and cracking of corrosion-resistant alloys (CRAs) and specific selection criteria of CRAs for application in downhole conditions.

New Metal Alloy Materials Slow Corrosion in Process Vessels

In this case study at a U.S. oil and gas facility, a new high-velocity thermal spray cladding solution helped stop corrosion where an older nickel-copper thermal spray coating and organic patch repairs had worn away.

U.S. Researchers Probe Localized Corrosion on Steel Pipes

According to U.S. researchers, a localized form of nanoscale corrosion appears responsible for unpredictably decreasing the working life of steel pipes used frequently in the oil and gas industry.

New Accident-Tolerant Fuel Cladding for Nuclear Environments

A multi-year research project involving Oak Ridge National Laboratory has led to the production of an accident-tolerant fuel cladding utilizing iron-chromium-aluminum alloys.Since the disaster at Japan’s Fukushima Daiichi Nuclear Power Plant in March 2011, scientists and engineers have searched for solutions to help prevent future accidents of that magnitude.
