Calcium Chloride and Minimizing Corrosion

The growing need for corrosion-inhibited deicers has prompted manufacturers to explore their production. One example of this is a new corrosion-inhibited grade of liquid calcium chloride introduced by General Chemical Corp. designed to meet or exceed Idaho''s and Washington''s deicer standards in all respects.

Metals | Boundless Chemistry - Lumen Learning

Aluminum is resistant to corrosion due to the phenomenon of passivation. A thin surface layer of aluminum oxide is formed when the metal is exposed to air. This oxide layer protects the aluminum beneath the surface from further oxidation. Like many other metals, aluminum can also be oxidized by water to produce hydrogen and heat:

General and localized corrosion of magnesium alloys: …

Filiform corrosion was observed in the uncoated AZ31, while general corrosion mainly occurred in some deposition coated alloys. Crevice corrosion can probably be initiated due to the hydrolysis reaction. Exfoliation can be considered as a type of intergranular attack, and this is observed in unalloyed Mg above a critical chloride concentration.

How desiccants can help prevent rust and corrosion

In the global auto industry, it is common for parts to be designed in one loion, manufactured in another and packaged and shipped to a third for final assely or storage. In some cases, these loions are relatively close, perhaps even in the same country. But in many other cases, parts manufacturing and final assely operations may be thousands of miles apart, necessitating large
