Interview: Bob Chalker on the 2021 Launch of AMPP

In this exclusive interview, Bob Chalker—CEO of the new corrosion and coatings nonprofit association—discusses many of the underlying motivations that led to the Association for Materials Protection and Performance (AMPP).

Improving the Durability of Packaging Materials

The packaging industry recognizes its responsibility in attaining a closed loop cycle through the use of green corrosion inhibitors. In this study, several papers impregnated with green inhibitors were investigated. During manufacturing, storage, and transport, humidity, salts, and other corrosive substances in the environment, as well as temperature fluctuations, can make metal parts more susceptible to corrosion.

A Circular Economy Approach from a Corrosion Engineer

Merging concepts like designing for purpose, maintaining with integrity, and decommissioning with a second life in mind are ideas that, if used in conjunction with adequate management tools, can help industries pursue the path of applying an effective corrosion management system.

Plans Unveiled for CORROSION 2021 Virtual Conference & Expo

The two-week event will provide a collaborative and convenient platform for corrosion and coatings industry professionals to network, learn, and develop new business.

Corrosion Basics: Stress Corrosion Cracking

As published in the January 2021 issue of Materials Performance (MP), this article explores the required elements for stress corrosion cracking to occur. Typically, these involve a susceptible alloy, the proper chemical environment, and an enduring tensile stress.

Some Aspects of Steam Condensate Corrosion

Diligent boiler feedwater treatment, involving mechanical deaeration and chemical treatment, is the primary defense against steam condensate corrosion. This article reviews further methods, including equipment design, materials selection, venting, reducing air ingress, and selecting steam traps.

Corrosion Behavior of a Novel Material—Open-Cell Aluminum Foam

The authors studied open-cell aluminum foams with different pore densities under marine conditions, with the objective of learning more about the corrosion behavior of these materials. The resulting deeper understanding is expected to lead to expanded utilization in advanced engineering applications.

Improving Fatigue Life for High-Strength Aluminum Alloys

A new study by engineers at Monash University has demonstrated improvements in the fatigue life of high strength aluminum alloys by 25 times, which the researchers believe could be significant for the transport manufacturing industry.

Evaluation of Florida Bridge Pilings

Many bridges in coastal areas are supported by precast pilings that are either continuously or periodically exposed to harsh saltwater conditions, requiring cathodic protection. These researchers studied two decommissioned pilings from the Veterans Memorial Bridge in Florida.

Bend Test of Concrete Power Poles

Concrete beams should be resistant against the influence of corrosive agents, environmental degradation, and mechanical forces. In this article, the effect of two different concrete mixing designs is investigated against the pole’s bend strength behavior.

Study: Radiation Can Slow Corrosion of Reactor Alloys

A team of researchers at the Massachusetts Institute of Technology and the Lawrence Berkeley National Laboratory have found that exposure to radiation can improve the resistance of certain alloys that could be used in fission or fusion reactors.

Sunflower Oil-Based Inhibitors Slow Corrosion in Offshore Arctic Conditions

After finding high efficiency in laboratory tests, scientists are intending to apply new bio-based corrosion inhibitors—developed on the basis of sunflower oil—in harsh Arctic conditions.

Moisture Drainage and Stand-Offs Impact on Insulation Wetting

Patterns of moisture trapping underneath insulation were visualized using moisture detection imaging, and a contact-free insulation system with low-point drains achieved maximum drainage efficiency (97%) and the least trapping.

Researchers Seek Better Fabrication Techniques for pH-Responsive Microcapsules

The new technique developed by University of Illinois researchers can potentially be used to make microcapsules that respond to changes in pH, which are useful for applications such as anticorrosion coatings.

PHMSA Plans to Modernize U.S. Gas Pipeline Safety Rules

PHMSA is proposing to clarify that cathodic protection rectifiers can be monitored remotely and to revise the requirements for assessing atmospheric corrosion on distribution service pipelines.
