Assessing the Risk of Coating Failure from Residual Soluble Salts

Residual soluble salts are contaminants on a substrate surface that affect coating performance. The primary soluble salts that the coatings industry must manage are in the form of chlorides, sulfates, and nitrates.

Installation Complete on First U.K. Long-Length Coated Rail Project

Zinc-rich coated rail, which protects in the most corrosive of environments, is being supplied in longer lengths and is seen as ideal for track environments, such as those in tunnels.

Canadian, U.K. Groups Collaborate on Corrosion Research for Marine Coatings

The European Marine Energy Centre and Canada’s Fundy Ocean Research Center for Energy kicked off a joint project to examine the differences in corrosion and underwater behavior of marine coatings on both sides of the Atlantic Ocean.

Steel Bridges Protected with Two-Coat Polyaspartic Urethane Coatings

A second generation of a polyaspartic urethane two-coat coating system with improved wet adhesion and corrosion resistance was developed in recent years for application in warm climates with high humidity.

Polyurea Coatings Protect Aging Concrete Wastewater Infrastructure

Advanced polyurea coatings and liners can provide strong, flexible waterproofing to bridge cracks and protect against future cracking and deterioration.

Corrosion-Resistant Thermal Spray Coatings Withstand Supercritical CO2 Environments

Researchers have concluded that HVOF-sprayed coatings comprised of UNS R50250, UNS N10276, UNS N06625, and UNS S31603 can provide a cost-effective corrosion mitigation method for infrastructure likely to be in contact with a mixture of wet supercritical CO2 and H2S.

Researchers Examine Corrosion of Lead Water Pipes in Aftermath of Flint

Even in the absence of funding for lead corrosion research, a team of scientists at the University of Virginia is pressing forward with a new project aimed at solving problems associated with leaching lead from water pipes.

Innovative Polymeric Solution for Flanged Pipework Protection

Flanged pipework can be isolated from corrosive environments by using a flexible, liquid-applied elastomeric material that can be peeled off for inspection and then resealed.

Evaluation and Repair of a Liquid Sulfur Holding Tank

This case study presents the results of evaluations and repairs made to a sulfur tank at a gas plant in central Alberta, Canada. The repairs exceeded the owner’s expectations for performance and have not required any subsequent concrete repairs of significance.

Medical Device Industry Turns to Plasma-Applied Coatings

To upgrade legacy medical devices under new regulations, the medical device industry is aggressively investigating and applying plasma-applied coatings to products such as stainless steel guide wires, catheters, stents, and vascular surgical tools.

Corrosion Basics: Coating New Construction Seagoing Vessels

Surface preparation and coating application during the new construction of a vessel compose a complex orchestration that requires the coordination of every department in a shipyard. It is also one of the most expensive parts of building a new vessel.

Zinc-rich Epoxy Primer Uses Glass Spheres, Zinc Activator to Enhance Corrosion Resistance

A novel, organic zinc-rich primer coating technology relies on a combination of zinc dust, hollow glass spheres, and a proprietary activator to provide cathodic protection with greatly improved mechanical properties (crack resistance) and adhesion.

Results Posted for NACE International’s 2016 Annual Corrosion Career Survey

Average annual salaries in 2016 are reported for corrosion professionals in the United States, Canada, United Kingdom, and Europe. A slight gain was seen for the United States and United Kingdom, while a larger increase was recorded in Canada.

Advances Made in Epoxy Coating Technology

A single-pack epoxy coating with epoxy-amine reactive functionality was recently developed that delivers reasonable shelf life and a high level of corrosion resistance that is comparable to two-component epoxy polyamide coatings.

What Do You Know about Inorganic Zinc Coatings?

Inorganic zinc silicate coatings, whether solvent- or water-borne, provide a number of unique challenges for the specifier and applicator. This article answers questions relating to selection, application, and maintenance of these coatings.
