Cold-Bonding Polymeric Technique Helps Restore U.K. Trains

A U.K. group specializing in train restoration identified polymeric cold-bonding as a superior solution to welding to help fix recurring problems with metal corrosion in diesel tanks.

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.

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.

Guide Helps Estimate Cost and Service Life for Protective Coatings

The practical guide was designed to help coatings engineers or specifiers determine candidate protective coating systems for particular industrial environments.

Waterproofing System Protects Landmark New York Bridge

Heavy traffic on the Verrazano-Narrows Bridge meant that the 50-year-old upper level deck required replacement to make way for a lighter-weight orthotropic deck consisting of more durable steel.

Trailer Study: Wax Coating Shows Promise in Resisting Corrosion

Salt spray exposure tests revealed the strength of wax-based coatings in withstanding exposure to sodium chloride (NaCL) as a corrosive agent in truck and trailer manufacturing operations.

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.

Graphene Nanoplatelets Boost Barrier Protection to Epoxy Coatings

The effective barrier properties of the graphene nanoplatelets may explain the corrosion mitigation observed on steel panels in both immersion testing and cyclic salt fog testing.

Fire-Resistant Coating Forms Heat Barrier for Reinforced Concrete

A new polyurethane-based nanocomposite coating system can be applied to steel and concrete without the need for sandblasting, thus reducing application time by half. It can also protect the substrate against fire for two hours without falling off.

Abrasives: Salt Contamination and Its Transfer

Soluble salts left on the surface can cause premature coating failures. As such, all steps and materials used require scrutiny to prevent the potential addition of salts during surface preparation and cleaning.

Dome Roof of Historic Mosque Receives Waterproof Repairs

The 128-year-old dome of the Shah Jahan Mosque near London, United Kingdom was suffering from corrosion-related perforations and leaks. A cold-applied, seamless roof was the solution.

Nickel-based Coatings May Slow Corrosion in Solar Power Plants

New research at the U.S. Department of Energy’s National Renewable Energy Laboratory is aimed at mitigating corrosion levels in concentrating solar power plants with nickel-based coatings.

U.S. Army Develops Sensing Network to Spot Aircraft Damage

Networked sensors open up possibilities for new onboard aircraft features that could immediately alert the flight crew to structural damage as it occurs, like matrix cracking and coating delamination.

Evaluating Internal Pipe Coatings with Electrochemical Impedance Spectroscopy

A new generation of high-temperature fusion-bonded epoxy coatings are being developed as a lower-cost alternative to alloy steels for protecting the internal surface of tubing, casing, flowlines, and pipelines.

Nickel-Cobalt Alloy Coating Protects Steel Fasteners from Hydrogen Embrittlement

Electroplating fasteners with a Ni-Co alloy can decrease hydrogen production on the coating’s surface and prevent hydrogen penetration into underlying metal.
