Coatings & Linings

Evaluation of Two Coatings on Substrates Cured in Air and Underwater

Researchers with PPG set about to study two coatings—cured for two weeks in both air and underwater—and their adhesion abilities in various conditions.

Association for Materials Protection and Performance (AMPP) Is Formed

Having launched on January 6, 2021, the new organization, Association for Materials Protection and Performance (AMPP), represents a combination of NACE International and SSPC: The Society for Protective Coatings.

Protecting Reinforced Concrete Structures with External Zinc Anodes

Several case studies show how the service life of reinforced concrete structures can be significantly and economically extended by using metallic zinc anodes to protect the steel reinforcement from further corrosion.

Epoxy Powder Hybrid Coatings with Improved Corrosion Resistance

The structure and morphology of the composite were characterized by Fourier transform infrared spectroscopy and scanning electron microscopy, and electrochemical impedance spectroscopy was used to study the corrosion resistance.

Newly Coated Tank Protection at Eastman Chemical Complex

When Eastman Chemical opted for a new urethane coating system on tanks at the front of its flagship plant, not just any applicator could do. The client needed expertise in access, aesthetics, and containment for removal of the prior lead-based coating.

Self-Healing Protection for Oil and Gas Assets

This article reports on the response of a commercially available self-healing epoxy coating to damage designed to simulate microcracking typically observed in protective coatings in the field.

U.S. Navy Utilizing Remotely Operated Vehicles to Check for Corrosion

The ROVs measure metal thickness, paint thickness, and cathodic protection (CP) voltage—a corrosion prevention technique the Navy uses that charges the hull at a certain voltage to slow down corrosion.

Electrochemical Corrosion Behavior of Micro-Arc Oxidation Coating on an Aluminum Alloy

The electrochemical corrosion behavior at different current densities was studied by using the potentiodynamic polarization and electrochemical impedance spectroscopy tests in combination with scanning electron microscopy.

Podcasts: Materials Performance Interview Series

In this new series, Materials Performance (MP) Magazine Editor Rebecca A. Bickham and Staff Writer Ben DuBose interview a wide range of corrosion experts to bring you the latest news and information regarding key technologies and industry trends.

Cold Spray Gains Momentum as U.S. Army Repair Technique

U.S. Army researchers have refined their high-pressure cold spray repair technique to the point where it is now the military’s preferred solution to corrosion damage and dimensional restoration.

Mitigating Boiler Corrosion at a Swiss Waste-to-Energy Plant

Officials at the plant were seeing accelerated corrosion on a fairly new boiler protected with weld overlay. They then evaluated four different thermal spray vendors who claimed to have the solution by having them each protect a patch inside the boiler.

Internal Lining Refurbishment for India’s Tallah Tank

A solventless food-grade epoxy lining was selected as the coating system, with reduced thickness, in part to reduce the tank load on supports that are more than 100 years old.

Members of NACE International, SSPC Vote to Approve Combination

Members of NACE International voted in April to approve the association’s proposal to combine with SSPC: The Society for Protective Coatings. During the two-week voting period, thousands of NACE stakeholders worldwide cast votes, with an overwhelming 89% voting in favor of combining forces with SSPC.

The Science Behind It: Coating Technology for Pump Energy Savings

Premature failures of pump components can be caused by cavitation phenomena, erosion-corrosion, and other mechanisms.

NACE International’s Annual Corrosion Career Survey Results for 2015

Corrosion professionals in North America and Europe have experienced another year of continued growth in career opportunities and salary levels, according to the 2015 Corrosion Career Survey conducted by Materials Performance magazine.
