Participating in technical standards development at NACE involves attending meetings...a lot of meetings. Well-run meetings are a great tool for exchanging information, working together, and developing consensus to make decisions or create documents. Here are some suggestions on how to conduct a technical committee meeting.
Corrosion can either take place locally to form a pit or crack, or it can extend uniformly across a wide surface. Proper surface analysis of the corroded sample is vital for evaluating corrosion characteristics and mechanisms, so the best materials, protective coatings, and corrosion-control measures can be selected.
Proper Coating Adhesion Is Essential for Long-Term Performance in Water and Wastewater Environments. Corrosion is a highly probable occurrence in water/wastewater facilities that can cause expensive repercussions and downtime. High levels of exposure to corrosive elements such as water, salt, acid, and chlorine are common, and there is a risk of irreparable damage to electrical equipment from corrosion. Therefore, electrical systems must be designed with the proper protection.
In Italy, where domestic nuclear power production has been halted, the need is ongoing to safely store low-level radioactive waste produced as a byproduct. The goal is to meet Italian and international requirements for temporary storage of low-level radioactive waste. The waste is stored in steel drums encased in concrete for radiological reasons. Relative humidity of 65% or lower must be maintained to prevent corrosion.
Several myths concerning the cause of reinforced concrete deterioration prevailed in the mid-20th century, but steel corrosion is by far the biggest durability issue for reinforced concrete structures.
A new class of high-temperature alumina-forming austenitic stainless steel alloys deliver both superior corrosion and creep resistance for many industrial environments.
NACE International has embarked on a new study, IMPACT, that not only addresses the economic effects of corrosion, but focuses on public safety, environmental concerns, management, and planning on a global basis.
For the DoD’s fleet of aircraft, environmental exposure can cause corrosion damage that leads to degradation of the airframe structure, electrical wiring and interconnection system, and avionics. While nondestructive evaluation (NDE) techniques such as ultrasonic testing have been developed for aircraft inspection, the primary means used by military maintainers to assess an aircraft for corrosion is generally a schedule-based inspection of the airframe Many times corrosion damage can go undetected and untreated in locations that are difficult to access, which can intensify structural damage and cause safety issues. To address this, a self-contained multi-modal corrosion sensor system has been developed to measure, record, and analyze environmental and corrosivity parameters that affect corrosion susceptibility and corrosion rate of a material.
A forensic investigation of unbonded, post-tensioning tendons on a large structure revealed relatively advanced levels of strand corrosion within and inboard of the end anchors. Strand corrosion within anchors was so advanced that wires had disengaged from the wedges, resulting in slip, contraction, and consequent load reduction in the strand.
Corrosion of the reinforcing steel in concrete is a worldwide problem that causes a range of economic, aesthetic, and utilization issues. However, if corrosion effects are considered in the design phase and the right decisions are made prior to construction, buildings can be constructed to resist corrosion.
Corrosion costs have compelled the Florida Department of Transportation (FDOT) Corrosion Research Laboratory (Gainesville, Florida) to investigate new technologies and methods that can assess concrete bridge structures for corrosion
Results of corrosion testing on eight alloys from five copper alloy families commonly used in the consumer electronics industry are presented. Short-term exposures were conducted in simulated consumer environments such as a salted carbonated cola beverage, artificial human perspiration, and phosphate-buffered saline.
An increasing number of wind turbine structures have been installed, particularly on monopile foundations. Corrosion experiences and mitigation strategies reported by the offshore wind energy industry for these foundations are discussed.

NACE International has embarked on a study—IMPACT—that goes beyond the economic effects of corrosion; it emphasizes how to integrate corrosion technology with organizational management systems to optimize corrosion decisions with respect to both cost savings and concern for safety and the environment.
