Materials Selection & Design

Modeling Corrosion Resistance of Reinforced Concrete Structures

The total present cost and lifecycle cost show that galvanized steel rebar provides the most cost-effective protection for reinforced bridge decks with a 100-year service life.

New Welding Technique Could Reduce Corrosion of Automotive Parts

Through testing and computer simulations, a research collaboration is working to show that a new welding technique could make the joint between light metal alloys more resistant to corrosion.

Researchers Concerned by Current Models for Nuclear Waste Storage

Research at The Ohio State University shows that the materials used by many countries to store high-level nuclear waste will likely degrade faster than expected due to the way those materials interact with each other.

Access-Fitting Position in Corrosion Management Programs

In upstream industries, corrosion monitoring is an indispensable feature in corrosion management. Corrosion coupons and corrosion probes can make a valuable contribution toward the understanding and control of a corrosion problem.

U.S. Marine Corps Tests New Cold Spray Technology

The cold spray process bonds metal to metal in a relatively low-heat environment in order to deposit a coating onto the substrate. If the process is approved, the technology could help reduce turnaround times and decrease repair costs.

An Environmentally Friendly Polyester Coil Coating Primer

A primer with ideal corrosion resistance and mechanical properties was developed by using waterborne saturated polyester, waterborne crosslinking agents, and Cr-Pb-free pigments and fillers with low-VOC content.

New Self-Powered Sensor Could Monitor Concrete Corrosion

Researchers and technology specialists in Denmark are working to develop a self-powered corrosion sensor to install inside steel-reinforced concrete structures, such as bridges.

General Motors Boosts Corrosion Prevention at New Assembly Plant

The $1.4-billion plant expansion in Arlington, Texas, USA, includes new robotics procedures and superior coating technologies, which are designed to enhance the corrosion resistance of automobiles.

Researchers Propose Less Corrosive Alternative to Road Salt

With the winter season underway in the Northern Hemisphere, a university research team is developing a more sustainable deicing solution for road infrastructure using grape skins and other agricultural waste.

Stress Cracking of Duplex Stainless Steel in Refining

The nature of duplex stainless steels (SS) makes them susceptible to failures observed in both austenitic and ferritic SS. Improper fabrication techniques lead to deleterious sigma and alpha prime phases, causing brittle failure.

Investigators: Corroded Pipe Led to U.S. Refinery Explosion, Fire

Investigators with the U.S. Chemical Safety Board say a June 2019 explosion and fire at the Philadelphia Energy Solutions (PES) refinery in Philadelphia, Pennsylvania, USA, occurred due to a corroded pipe elbow in the refinery’s alkylation unit.

Research Team Examines Pipeline Failure Prediction Models

In a new study, researchers at Concordia University and the Hong Kong Polytechnic University examine many methodologies currently used by industry and academics to predict pipeline failure—and their limitations. The researchers cite more than 10,000 pipeline failures in the United States alone as the motivation for their research, according to U.S. Department of Transportation data.

Pitting Test in Ammonia Flue Gas Desulfurization Slurry

Ammonia flue gas desulfurization (AFGD) has many advantages, but often it cannot work to its full capacity due to corrosion. In this study, seven widely used metal materials were placed in a custom-made device containing AFGD slurry to test for pitting corrosion.

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.

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.
