Welcome to the early December 2019 Corrosionpedia News Roundup. For this edition, we highlight an incident where a pedestrian was injured as the result of a corroded streetlight pole. We see exciting developments in the proactive management of corrosion within both a United States municipality and a European startup company. NACE opens registration for its famous conference that is all about corrosion, and nanotechnology research has the potential to revolutionize marine structure corrosion prevention.

Pedestrian Injured Because of Light Pole Corrosion

In the city of Chicago, Illinois, light poles are becoming increasingly dangerous as a result of the often unseen corrosion they are undergoing. Some light poles and sign poles have been allowed to corrode to the point of complete material failure, which typically involves them falling violently to the ground.

Recently, an injury occurred as one of these poles hit a pedestrian. The poles are frequently found to have rust around their bases, which is most likely a result of their contact with road salt and water in that part of the structure. However, it can be difficult to proactively detect the corrosion due to ornamentation and other aesthetic shapes that are placed around the poles. The city says it is investigating the situation.

Reinforcing Steel Corrosion Study Released

Research has been shared with the scientific community about the factors requiring further study to understand exactly how to prevent or slow the corrosion of steel reinforcing bar in concrete structures. The focus of this study highlights the factors promoting corrosion due to exposure to harmful chlorides. The information released by RILEM, a materials and structures research organization, provides direction for scientists on areas worth further research. There are currently many projects intended to prevent and monitor rebar corrosion, and there are also alternative materials being developed that do not corrode when used as concrete reinforcement.

Registration Opens for CORROSION 2020 Conference

NACE will be hosting its CORROSION conference again in 2020, and registration for the event is now open. CORROSION will be held in Houston, Texas at the George R. Brown Convention Center from March 15 to March 19, 2020. CORROSION is the largest conference that focuses solely on corrosion, and is for technical experts, academics, students and executives that are involved in the prevention, monitoring or research of corrosive processes. The conference has networking events, speaker series, company booths and award ceremonies for attendees to take part in.

Proactive Corrosion Inhibition in Water Lines

It has been common lately to hear about municipalities reacting to corrosion and high levels of lead in their water systems after its too late, but the Rivanna Water and Sewer Authority and other municipal departments in the Charlottesville, Virginia area are solving water treatment corrosion problems before they arise. The Rivanna Water and Sewer Authority has had a corrosion inhibition process in place for decades and its water lines are currently delivering safe drinking water with hazardous material levels below regulatory mandates. The organization realized, however, that they must stay on top of the risk of corrosion. Therefore, they are rolling out an upgraded corrosion inhibition plan in 2020 to maintain safe drinking water for its constituents.

Funding Secured by Corrosion StartUp Company

CorrosionRADAR, a corrosion detection and monitoring company, has secured EUR 1 million financing. The funding is being provided by the Midlands Engine Investment Fund - Proof of Concept segment, the government of the United Kingdom and some private investors. CorrosionRADAR develops technology that can be used to automate corrosion detection in the oil and gas industry. The technology also allows for proactive maintenance rather than reactive maintenance by providing information about corrosion risks before failure occurs. The money will be used to expand CorrosionRADAR’s operations and continue its research.

Nanotechnology Could Help Stop Marine Corrosion

Researchers in Europe are exploring different applications where nanotechnology could be used to prevent marine corrosion. Saltwater can cause corrosion to rapidly develop on ship hulls and other marine structures. Currently, traditional coatings are primarily used to prevent corrosion, but scientists at the National Iberian Laboratory are looking at coatings that are formulated using nanotechnology. These coatings are intended to be better able to protect maritime structures. The nano coatings will also help prevent biofouling, a process where structures have their geometry altered by aquatic organic substances.
