New Safe Containment Project Cuts Corrosion Risk at Chernobyl

The new containment structure, moved into position in November 2016, includes a ventilation system that developers say will help ensure there is no need to replace the coating used to control corrosion.

U.S. House Panel Concludes State, Federal Failures behind Flint

The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.

Proposed Changes to Gas Transmission Pipeline Regulations Intended to Increase Safety

A notice of proposed rulemaking issued by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety outlines significant changes to the Pipeline Safety Regulations that are intended to increase the safety of natural gas pipelines.

Battling Building Envelope Corrosion

Efficiently managing the effects of concrete corrosion can extend the life of a building; however, concrete is not the only component threatened by corrosion. On any building, both the cladding and fasteners holding it in place are exposed to varying degrees of corrosion.

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.

Key Indicators Can Reveal Signs of Concrete Parking Structure Corrosion

Experienced concrete maintenance and restoration specialists explain the unique challenges in protecting parking structures from a constant onslaught of environmental stressors and wear and tear, along with examples of successful repair techniques.

Test Protocol Evaluates Concrete Repair with Sacrificial Anodes

One of the most common drivers of concrete repairs is corrosion of the concrete’s steel reinforcement, often caused by chloride ions in the environment entering the concrete and eventually reaching the embedded steel.

Corrosion-Resistant Thermal Spray Coatings Withstand Supercritical CO2 Environments

Researchers have concluded that HVOF-sprayed coatings comprised of UNS R50250, UNS N10276, UNS N06625, and UNS S31603 can provide a cost-effective corrosion mitigation method for infrastructure likely to be in contact with a mixture of wet supercritical CO2 and H2S.

Researchers Examine Corrosion of Lead Water Pipes in Aftermath of Flint

Even in the absence of funding for lead corrosion research, a team of scientists at the University of Virginia is pressing forward with a new project aimed at solving problems associated with leaching lead from water pipes.

Medical Device Industry Turns to Plasma-Applied Coatings

To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.

Cold-Bonding Polymeric Technique Helps Restore U.K. Trains

A U.K. group specializing in train restoration identified polymeric cold-bonding as a superior solution to welding to help fix recurring problems with metal corrosion in diesel tanks.

Alumina-Forming Austenitic Alloys Resist High-Temperature Corrosion

A new class of high-temperature alumina-forming austenitic stainless steel alloys deliver both superior corrosion and creep resistance for many industrial environments.

Zinc-rich Epoxy Primer Uses Glass Spheres, Zinc Activator to Enhance Corrosion Resistance

A novel, organic zinc-rich primer coating technology relies on a combination of zinc dust, hollow glass spheres, and a proprietary activator to provide cathodic protection with greatly improved mechanical properties (crack resistance) and adhesion.

Researchers Use Underground Radar to Detect Post-Storm Infrastructure Damage

A new underground radar technology system developed at Louisiana Tech University is helping a local city spot damage to infrastructure that had gone undetected since Hurricane Katrina.

UAVs Capable of Inspecting Ship Tanks for Signs of Corrosion

By using UAV technology, survey times and staging costs associated with visual condition checks of remote structural components in ship tanks can be significantly reduced.
