According to the US Department of Defense, corrosion costs the Navy approximately US$7 billion every year. That's certainly an incentive for developing a method of keeping military vehicles from rusting. Now, researchers from the Office of Naval Research and The Johns Hopkins University Applied Physics Laboratory may be onto something. They're looking into the use a powder that could allow scratched or chipped paint to "heal like human skin." Read More

Stainless magnesium breakthrough bodes well for manufacturing industries

By - August 29, 2013 2 Pictures
Magnesium alloys are very attractive for a range of weight-sensitive applications. They have the largest strength-to-weight ratio of the common structural metals, are lighter than aluminum and are particularly favored for being easy to machine and for their ability to be die cast to net shape. Unfortunately, magnesium alloys tend to corrode too easily. A team at Monash University in Australia has now discovered a novel and potentially game-changing approach to the problem: poisoning the chemical reactions leading to corrosion of magnesium alloys by adding a dash of arsenic to the recipe.
