Titanium - Corrosion by Water
Titanium is highly resistant to corrosion by water, steam and seawater, except at elevated temperatures. Other corrosion mechanisms such as stress corrosion cracking, corrosion fatigue, biofouling, microbiologically influenced corrosion, crevice corrosion and galvanic corrosion are also covered.
Information sheet Salt spray testing – why it should not
Magnesium ions, whether from the environment (sea salt) or in a zinc alloy, promote the formation of protective corrosion products in the presence of sodium chloride, thus reducing corrosion rates. This explains why zinc-magnesium-aluminium coatings show
This specifiion covers a magnesium alloy in the form of sand castings. Appliion These castings have been used typically for parts operating up to 300 °F (149 °C), and requiring moderate strength and excellent corrosion resistance, but usage is not limited to such appliions.
Reaction of Magnesium Hydride with Water to Produce …
In this paper, magnesium hydride was used to react with water to produce the hydrogen gas. Magnesium hydride is the chemical compound MgH2, which contains 7.66% by weight of hydrogen. Although the concept of reacting chemical hydride with water to produce hydrogen is not new, there have been a nuer of recent published papers which might be employed to power fuel cell devices for …
