When contaminants absorb the light, they either turn into a gas, or the pressure removes the particles from the surface. This leaves the bare metal clean and ready for coating, without damaging its structural integrity.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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.
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 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.
Premature failures of pump components can be caused by cavitation phenomena, erosion-corrosion, and other mechanisms.
