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.

Study: Graphene Technology Boosts Performance of Epoxy Coatings

Initial test results have shown higher corrosion resistance, increased mechanical strength, and better abrasion resistance when using epoxy resin-based coatings formulated with graphene.

Test Samples of Reinforced Concrete Are Often Too Small

A recent study from European university scientists suggests that samples of reinforced concrete need to be larger to ensure accuracy in corrosion detection.

Strategic Planning at NACE International: Eleventh in the Series

The key to effective planning involves converting decisions to actions. For the process to be most effective, the results of the actions are monitored and shared, thus continuing an unending process.

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.

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.

U.K. Grant Targets Sensors for Corrosion Protection in Heating, Cooling Units

A collaborative project funded partly by the U.K. government is looking to develop cost-effective sensors capable of measuring the corrosion rates of metals used in water-based heating and cooling units.

Strategic Planning at NACE International: Implementation Plan

In the 10th part of this series, we explain how the implementation plan is a tool that can be used to break annual key strategies into increasingly smaller tasks.

Failure of Water Wall Tubes Caused by Hydrogen Embrittlement from Severe Underdeposit Corrosion

In a CORROSION 2017 paper, authors discussed two water wall tubes in a multistage flash distillation plant’s operating boiler that experienced failure after 14 years of service.

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.

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.

Strategic Planning at NACE International: Ninth in a Series

A number of board key strategies and definitions of success were agreed upon at the fall 2017 meeting of the NACE International Board of Directors.

Coupons for Cathodic Protection Evaluation of Mixed-Metal Piping Systems

The measurement and interpretation of cathodic protection (CP) data in plants or other complex facilities present inherent challenges where mixed metals are electrically continuous within the protected structures’ CP system.

Analysis Cites Flawed Management in Oroville Dam Failures

Researchers investigated corrosion-related failures of the Oroville Dam Gated Spillway in California, concluding that inappropriate standards, guidelines, procedures, and processes were used in its evaluations.

Self-Consolidating Concrete Shows Promise in Bridge Repairs

A Virginia Department of Transportation investigation studied the use of self-consolidating concrete with and without galvanic anodes to repair substructure elements with vertical and overhead sections.
