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.

Evaluating Internal Pipe Coatings with Electrochemical Impedance Spectroscopy

A new generation of high-temperature fusion-bonded epoxy coatings are being developed as a lower-cost alternative to alloy steels for protecting the internal surface of tubing, casing, flowlines, and pipelines.

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.

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.

Historic Corrosion Tools Tell the Story of Early Corrosion Control

A collection of antique instruments illustrates the rich history of the East Bay Municipal Utility District’s corrosion department.

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.

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.

Study Evaluates Chloride Limits for Structural Reinforced Concrete

Research on chloride limits for reinforced concrete found a relationship between the initial calculated total chloride content and the measured water-soluble chloride content in hardened concrete.

Device Measures Nanoscale Crevice, Pitting Corrosion in Real Time

University researchers developed a device called a surface forces apparatus (SFA) to get a real-time look at the process of crevice and pitting corrosion on confined metallic surfaces.

Study: Lack of Corrosion Controls Caused Flint Water Crisis

Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.

Retrofitting Wind Turbine Monopiles with Cathodic Protection

A strategy to provide wind turbine monopiles with a corrosion prevention system included resealing the J-tubes to prevent seawater flushing and installing a galvanic cathodic protection system inside the submerged section of the monopile.

Self-Consolidating Concrete Shows Promise in Bridge Repairs

A Virginia Department of Transportation investigation studied the use of self-consolidating concrete with and without galvanic anodes to repair substructure elements with vertical and overhead sections.

New U.K. Collaborative Research Project Targets Oil, Gas Corrosion

Researchers from BP and several prominent European universities were awarded a contract to investigate the processes that cause surface degradation and develop new mitigation strategies.

Graphene Nanoplatelets Boost Barrier Protection to Epoxy Coatings

The effective barrier properties of the graphene nanoplatelets may explain the corrosion mitigation observed on steel panels in both immersion testing and cyclic salt fog testing.

New Tantalum Alloy Resists Highly Corrosive Environments

The results of recently completed trials show that adding low levels of ruthenium improve the corrosion and hydrogen enrichment resistance of a tantalum alloy in both hydrochloric and sulfuric acids at high temperatures.
