With the Delhi Pillar (Delhi, India), improved corrosion resistance was achieved through alloy additions to the iron, but this was the result of luck with the ore used. It was not until the late Victorian era that scientific investigations produced the precursors to the modern corrosion-resistant steels in use today. The discovery in 1882 of...

Proper corrosion protection is critical in steel construction. Protective coating systems on bridges and other steel structures that fail due to poor durability or through incorrect specification are expensive, inconvenient and may have a negative impact on public health, safety and the environment when these systems are repaired or replaced. A simple means of specifying...

The 309th Aerospace Maintenance and Regeneration Group (309 AMARG) at the Davis-Monthan Air Force Base (Tucson, Arizona, USA), commonly known as “The Boneyard,” is probably one of the strangest airfields in the world. It’s here that the U.S. Air Force, Navy-Marine Corps, Army, Coast Guard, and several federal agencies (including NASA) store their obsolete, unwanted,...

Of the many wonderful things that Howard Carter found in the tomb of Tutankhamun in 1922, a small iron dagger may seem insignificant compared to the numerous gold, silver, and beautifully colored objects that the Egyptian boy king is famous for. But to the corrosionist, this item is remarkable because it just may be the...

Corrosion, being a reaction between a material and its environment, can be minimised by creating a benign environment rather than looking at expensive materials such as iridium. And, in theory, it is not hard to find a very benign environment—simply head upwards for 100 km or so into space.
