U.S. Airmen Target Noninvasive Methods to Spot Aircraft Defects

Airmen with the 19th Maintenance Squadron at the Little Rock Air Force Base in Arkansas are using nondestructive inspections to identify potential cracks in a variety of aircraft parts.

Improved Packaging Film with Vapor Phase Inhibitors, High Recycle Content

Plastic packaging films can be readily impregnated with vapor-phase corrosion inhibitors (VCIs) to provide corrosion protection, in addition to the basic physical barrier afforded by the plastic.

Researchers Test Materials in Tropics to Better Preserve Military Equipment

The Department of Defense Corrosion Policy and Oversight Office enlisted partners to expose various materials to outdoor tropical regions.

Portable X-ray Diffraction Units Boost Efficiency of Corrosion Analysis

New x-ray diffraction technologies are enabling corrosion analysis to be carried out much more quickly and thoroughly by using a portable unit in the field.

U.S. Army Seeks Biodegradable Bullets to Limit Soil, Water Corrosion

The U.S. Army wants to use biodegradable ammunition during training exercises, due in large part to how existing bullets can corrode and pollute the soil and water.

PHMSA Eyes Safety Upgrades on Hazardous U.S. Liquid Pipelines

New regulations for hazardous liquid pipelines are part of a series of changes from PHMSA aimed at improving pipeline safety across the United States.

Proposed Changes to Gas Transmission Pipeline Regulations Intended to Increase Safety

A notice of proposed rulemaking issued by the U.S. Department of Transportation’s Pipeline and Hazardous Materials Safety outlines significant changes to the Pipeline Safety Regulations that are intended to increase the safety of natural gas pipelines.

Long-Term Field Performance of an Organic Corrosion Inhibitor for Reinforced Concrete

Reinforced concrete samples with an organic corrosion-inhibiting admixture were exposed in a road salt environment in the Swiss Alps and periodically inspected over 18 years using a number of test methods.

U.S. House Panel Concludes State, Federal Failures behind Flint

The U.S. congressional committee investigating the water crisis in Flint, Michigan issued final letters citing failures at all levels of government, including problems at both the Michigan Department of Environmental Quality and the U.S. Environmental Protection Agency.
