Nickel-Rich Coating for Saline-Alkali Soil Grounding

To improve the corrosion resistance of the grounding grids in saline-alkali soil, the authors fabricated a conductive and anticorrosive coating. After a series of tests, results indicated that an increase of nickel powder in the coating can lead to its electrical conductivity enhancement.

Pocket-Sized Cathodic Protection Interrupter for Field Use

The pocket-sized cathodic protection (CP) interrupter records continuous waveforms during close interval surveys and provides accurate and defensible data. The technology includes both high-speed waveform datalogging and automated waveform analysis.

Study Evaluates Offshore Coating Performance on Stainless Steel

The objectives of the study were to develop a protocol for testing protective coating performance on pitted SS, evaluate how various surface preparation methods affect the coating performance on pitted SS, and determine a reliable coating application procedure to cover the pits with a holiday-free film so the integrity of offshore pitted SS is improved.

Water Repellency Technology Mitigates Corrosion Under Insulation Risk

The hydrophobic WR-Tech additive leads to stone wool, mandrel-wound pipe sections with significantly less water absorption relative to industry standards; faster drying rates; and durability over a wide range of potential CUI temperatures.

Corrosion Basics: Inhibitors for Waters of Low to Moderate Salt Concentrations

It is important to maintain inhibitor concentrations at a safe level in waters containing dissolved salts, particularly if these include chlorides.

Significance of Evaluation Methods for Surface-Applied Inhibitors

This article discusses the performance and relative importance of a recent testing program for corrosion inhibition and other performance parameters using documented test methods.

Vapor Corrosion Inhibitors for Tank Bottom Corrosion Control

A study was recently conducted to determine the viability of vapor corrosion inhibitor (VCI) technology in mitigating corrosion. Overall, VCIs were found to be effective in mitigating corrosion when recommended dosages are used, and they could also be used in combination with impressed current CP systems.

Perforated Offshore Monopile for Corrosion Control, Marine Habitats

Recent field experiments demonstrated that a cathodically protected perforated monopile structure could create an environment with more favorable corrosion mitigation, air quality, and water chemistry compared to a sealed structure. A newly designed perforated offshore monopile system could help mitigate corrosion within the often flooded interiors of offshore wind turbine support structures.

Corrosion Basics: Coating Condition Surveys

Several elements of preplanning are necessary to effectively execute the condition survey. The first is a logical breakdown of the facility, and the second is to have a grading system to evaluate the observed conditions.

Corrosion Management and Associated Implementation Issues

Any corrosion management implementation process should comprise three phases: pre-implementation, implementation, and post-implementation. Any shortcomings will adversely affect the outcome, effectiveness, and quality of the process. This article discusses corrosion management implementation issues and shortcomings that were observed during various campaigns or audits from around the world.

Lasers Could Replace Sanding, Blasting for U.S. Air Force

U.S. Airmen with the 60th Maintenance Squadron (MXS) at Travis Air Force Base in California, USA are one of two bases currently testing a pair of lasers as a new method of removing paint and corrosion on aerospace ground equipment. They say their traditional method involves the use of an orbital sander or blasting machine.

Corrosion Basics—Why Metals Corrode

Corrosion failures are often subtle and a result of invisible localized effects in the form of pits, intergranular corrosion, or attack within crevices.

The Humble Building Material that Shelters Millions Across the Globe

Corrugated iron has been and continues to be an invaluable building material that deserves to be taken seriously. It shows that steel can be simply and cheaply formed to a useful shape, protected from corrosion by a range of coatings, and made accessible to citizens in all corners of the globe.

Exploring Differences in Epoxy and Polyurethane Floor Coatings

Experts with a coatings specialist company explain the differences between floor coating systems based on polyurethanes and epoxies, and why the selection often depends on jobsite location. With each system offering differing properties suited to specialized uses, choosing the wrong solution can lead to costly repairs or even complete floor failure down the line.

Corrosion Basics—Safe Application of Protective Coatings

In every industrial environment, the safety factor is an important consideration. In some environments, including the application of protective coatings, it is of overriding importance. This article explores many of the safety factors that need to be considered.
