News Roundup: COVID-19 and the Corrosion Control Industry

To keep you updated on the coronavirus pandemic, MP is compiling this regular guide of news and interviews as it pertains to the corrosion industry and its path forward in the era of COVID-19.

U.S. Navy Utilizing Remotely Operated Vehicles to Check for Corrosion

The ROVs measure metal thickness, paint thickness, and cathodic protection (CP) voltage—a corrosion prevention technique the Navy uses that charges the hull at a certain voltage to slow down corrosion.

Nomination Period Opens for 2021 MP Corrosion Innovation Awards

The nominating period is now open for next year’s Corrosion Innovation of the Year Awards, with winners recognized in a wide range of categories related to corrosion prevention and mitigation.

Electrochemical Corrosion Behavior of Micro-Arc Oxidation Coating on an Aluminum Alloy

The electrochemical corrosion behavior at different current densities was studied by using the potentiodynamic polarization and electrochemical impedance spectroscopy tests in combination with scanning electron microscopy.

Building a Corrosion Management System via Material Sustainability and Stewardship

The goal is to foster a technical society of forward-looking, proactive professionals equipped to support sustainability in tangible, meaningful ways via knowledge, standards, and a vision for future generations.

Cold Spray Gains Momentum as U.S. Army Repair Technique

U.S. Army researchers have refined their high-pressure cold spray repair technique to the point where it is now the military’s preferred solution to corrosion damage and dimensional restoration.

Applying Over-the-Line Potential Surveys in Water/Wastewater Pipelines

Researchers performed two case studies to determine if over-the-line potential surveys could be successfully applied to electrically discontinuous water/wastewater lines and if the results aligned with the direct assessment methods.

Corrosion Management and Risk-Based Inspection

Risk-based inspections are believed to be one of the most efficient types of inspections, based on numerous evaluations of site visits and of asset integrity audits.

Water-Based Corrosion Inhibitors for Reinforcing Bars

Open circuit potential, electrochemical polarization, salt spray testing, and immersion testing in sodium chloride solution were employed to evaluate the anticorrosive ability of the water-based conversion film.

Members of NACE International, SSPC Vote to Approve Combination

Members of NACE International voted in April to approve the association’s proposal to combine with SSPC: The Society for Protective Coatings. During the two-week voting period, thousands of NACE stakeholders worldwide cast votes, with an overwhelming 89% voting in favor of combining forces with SSPC.

Corrosion Basics: ICCP for Atmospherically Exposed Reinforced Concrete Structures

Impressed current anodes for atmospherically exposed steel in concrete are very different from anodes for underground and underwater applications.

Corrosion Basics: Open Recirculated Cooling Water Systems

There are certain fundamental considerations that should be understood in relation to open recirculated systems.

Corrosion Basics: Locating Pipeline Coating Defects with a Pearson Survey

One of the first successful techniques for locating coating defects (holidays) on buried pipelines using surface electrical measurements is the Pearson survey, named after its inventor.

Corrosion Basics: Steam Generation in Power Plants

The greatest use of high-temperature water and steam is in electrical power generation. Historically, fossil fuels were used almost exclusively to heat water for steam until the introduction of nuclear power steam generators. This article briefly summarizes corrosion considerations for fossil fuel and nuclear fuel steam plants.

Strategic Planning at NACE International: Eighth in a Series

Given that the October print issue of MP is focused on CORROSION 2018, it seems appropriate to describe some of the strategic planning-related activities that will occur at this upcoming conference.
