Nano Non-Skid Coating Provides Sustainable Offshore Safety Solution

This article details how a coating applicator is overcoming challenges through the use of an innovative protective coatings pump design, which features a new single-coat carbon nanotube with a non-slip deck coat slurry.

CoatingsPro Magazine Names Winners of 2021 Contractor Awards

Through the annual program, CoatingsPro showcases projects and crews that demonstrate excellence in the commercial and industrial high-performance coatings sectors.

Failure Analysis and Design Considerations: Fluid Velocity Effects

Any mechanical disturbance of the protective film can stimulate attack of the underlying metals until either the protective film is re-established, or the metal has been corroded away. Erosion-corrosion is encountered most frequently in pumps, valves, centrifuges, elbows, impellers, inlet ends of heat exchanger tubes, agitated tanks, and so forth.

AMPP Technical Exchange on Ship Biofouling—A Success Story

In this roundtable discussion, shipping industry leaders within an AMPP Technical Exchange Group (TEG532x) share success stories from their ongoing collaboration. Guests include Elisabeth Charmley, Naval Architect for one of the world's largest ship managers; Johnny Eliasson, Hull and Coatings Engineer at Chevron Shipping; and Buddy Reams, Captain USCG (retired), Chief Technical/Maritime Officer of AMPP.

Extending the Service Life of a Historical Concrete Building

The repair was designed with a prediction of 100 years of service life extension. This was achieved with a steel coating and a concrete coating (barrier effect) that produced a similar or better protective effect than recorded during the evaluation.

U.S. Marine Corps Explores Laser Ablation for Aircraft Components

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.

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.
