Development of WC-Ni Cermet Brazing Process

In this case study, the serviceable lifetime of an impeller with an applied WC-Ni brazing layer on the surface measured almost eight times longer than an unbrazed impeller.

Cruise Ship Tests Surface Prep Kit to Boost Maintenance Efficiency

A novel corrosion control prevention kit utilizing shrouded surface preparation tools and demonstration videos is designed to improve the efficiency of in-house maintenance crews for maritime assets. Chris Patenaude, director of maritime and industrial sales at the company and also a NACE International-certified Coating Inspector Program (CIP) Level 3 Inspector, witnessed many common pitfalls firsthand in his prior role as global fleet superintendent for coatings and linings at cruise line operator Royal Caribbean International (Miami, Florida, USA).

Novel Design, Coatings System Resists Weathering at Tropical Complex

The combination of a unique architectural design finished with fluoropolymer coil coatings is geared to provide seacoast corrosion protection for upscale condominiums in Florida. The unique climate concerns to the region prompted an innovative concept from globally renowned architecture company Bjarke Ingels Group (Brooklyn, New York, USA).

Fusion-Bonded Epoxy Coating Protects Water Pipeline from Corrosion

To protect against corrosion, the water pipeline was lined internally with cement mortar after applying fusion-bonded epoxy with an abrasion-resistant overcoat.

Comparing Coating Equality Through Performance Data

For specifiers, contractors, and asset owners, it is necessary to make careful, informed decisions about which coatings to use for particular projects.

Artificial Neural Network Developed to Monitor Condition of Tank Coatings

Embedded technologies can provide monitoring capabilities that capture the onset of tank coating deterioration and follow the evolution of damage.

Field Joint Coatings

Engineering and selecting the most adequate and appropriate pipeline coating depends on a multitude of factors. Careful analysis of several critical factors must be considered, such as the pipe diameter, the service pressures or operating temperatures of the transport materials, the soil conditions if installing a landline, construction techniques for installation, cathodic protection (CP), and whether impressed current CP or sacrificial CP will be used.

Corrosion on the High Seas: How Ship Owners Battle Rust

Because seawater contains a significant concentration of dissolved salts and is very corrosive to steel, infrastructure and assets in or near marine environments are particularly susceptible to corrosion.

2018 Deadline Nears for New U.S. Underground Storage Tank Rules

The third and final deadline for underground storage tank owners and operators to meet new federal requirements from the U.S. Environmental Protection Agency for spill, overfill, and corrosion protection is October 13, 2018.

PHMSA: Weight on Keystone Pipeline Led to Coating Failure, Oil Spill

The installation of a weight on the Keystone oil pipeline in South Dakota upon its construction in 2008 appears to have caused mechanical damage to the coating, leading to a recent rupture and oil spill.

Thin Carbon Coating Reduces Carbon Corrosion in Water Electrolysis

Researchers have developed an alternative, less expensive anode material for alkaline water electrolysis, which they say promotes less carbon corrosion. The researchers say their new nanostructured catalyst can reduce the rate of carbon-induced corrosion often experienced in alkaline water electrolysis, used to produce hydrogen from renewable resources.

U.S. Air Force Targets New System to Evaluate Aircraft Coatings

A new system for evaluating coating performance is expected to accelerate the screening, qualification, and implementation of new aircraft coatings.

The Science Behind It: Effects of Silane Additives on Corrosion Resistance and Durability of Mortar

Silane coupling agent additives were used in mortar in varying proportions, and the effect of the coupling agent content on the mortar’s corrosion cracking resistance and durability properties was studied.

Thermal Imaging Used for Nondestructive Testing of Concrete Pillars

Russian scientists recently used a thermal imaging technique to study the corrosion of steel reinforcement within 14 reinforced concrete pillars.

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.
