Researchers Tout Three-Dimensional Printing Breakthrough for Metal Alloys

Researchers with the Lawrence Livermore National Laboratory and several other groups achieved a breakthrough in the three-dimensional printing of Type 316L stainless steel alloy.

Study Evaluates Chloride Limits for Structural Reinforced Concrete

Research on chloride limits for reinforced concrete found a relationship between the initial calculated total chloride content and the measured water-soluble chloride content in hardened concrete.

Device Measures Nanoscale Crevice, Pitting Corrosion in Real Time

University researchers developed a device called a surface forces apparatus (SFA) to get a real-time look at the process of crevice and pitting corrosion on confined metallic surfaces.

Study: Lack of Corrosion Controls Caused Flint Water Crisis

Led by university researchers, the findings of this new study support the understanding that lead leached into the pipes system in Flint, Michigan, because the water wasn’t treated to prevent corrosion.

Retrofitting Wind Turbine Monopiles with Cathodic Protection

A strategy to provide wind turbine monopiles with a corrosion prevention system included resealing the J-tubes to prevent seawater flushing and installing a galvanic cathodic protection system inside the submerged section of the monopile.

Self-Consolidating Concrete Shows Promise in Bridge Repairs

A Virginia Department of Transportation investigation studied the use of self-consolidating concrete with and without galvanic anodes to repair substructure elements with vertical and overhead sections.

New U.K. Collaborative Research Project Targets Oil, Gas Corrosion

Researchers from BP and several prominent European universities were awarded a contract to investigate the processes that cause surface degradation and develop new mitigation strategies.

Graphene Nanoplatelets Boost Barrier Protection to Epoxy Coatings

The effective barrier properties of the graphene nanoplatelets may explain the corrosion mitigation observed on steel panels in both immersion testing and cyclic salt fog testing.

New Tantalum Alloy Resists Highly Corrosive Environments

The results of recently completed trials show that adding low levels of ruthenium improve the corrosion and hydrogen enrichment resistance of a tantalum alloy in both hydrochloric and sulfuric acids at high temperatures.

Researchers Eye Advanced Sensors to Monitor Buried Infrastructure

Novel advanced sensors were attached to a hazard-resilient plastic pipeline installed underground and tested through a simulated fault rupture.

Strategic Planning at NACE International: Seventh in a Series

The plan for success has three elements: key strategic initiatives, implementation plans, and review and reload sessions. In this month’s post, we introduce all three steps in the plan for success process.

Degradation of a Thrust Bearing in a Lift Pump on an Electromotor Offshore Platform

This article discusses the causes of bearing failure, its avoidance, and a repair method for damaged thrust bearings.

Detecting Corrosive Sulfides Challenges U.S. Shale Operators

Many modern tests focused on the detection of sulfate-reducing bacteria as corrosive agents in metal oil and gas pipelines could be missing a separate bacterial family also responsible for corrosion.

High Pressure Key to More Advanced Metal Alloys

A new study suggests that high pressure could be the key to developing advanced metal mixtures that are lighter, stronger, and more resistant to heat and corrosion than conventional alloys.

Soil-Side Corrosion Causes Premature Failure of Oil Storage Tank Bottom Plates

Without an effective cathodic protection system and no other means of corrosion control, the tank floor was exposed to a severe form of bacterial and underdeposit corrosion.
