Iridium is a hard, brittle member of the so-called platinum group of metals in the periodic table. As an alloying element, it increases the corrosion resistance of titanium and palladium. We know that corrosion is a reaction between a material and its environment, so why not have a look at the most corrosion resistant metal in the periodic table.

A new study from the Global Brake Safety Council suggests the use of substandard materials and processes in automobile brake pads could be leading to accelerated failure modes. The council was formed in 2014 to advocate and raise awareness for high standards in brake safety while ensuring responsible manufacturing in the automotive industry.

Although atmospheres can be classified into four basic types, most of them are mixed and present no clear lines of demarcation. Furthermore, the type of atmosphere may vary with the wind pattern, particularly where corrosive pollutants are concerned.
