Arsenic protects magnesium alloy corrosion




Good news for the automotive, aerospace and electronics industries. Australian scientists at Monash University found a way to reduce the corrosion of metals on the basis of magnesium. For it is proposed to add to the alloy arsenic. Magnesium is lighter than aluminum alloys and could find application in many fields, if not for their poor resistance to corrosion. Scientists are working not only on frost wire . Their attention directed to a light metal.

According to the web site e! Science News, Associate Professor Nick Birbilis created a magnesium alloy with significantly improved resistance to corrosion. To do this, the alloy has been added to them a little bit of arsenic.

If magnesium alloys come close in their properties to stainless metals, they will play a more important role in energy conservation and transportation industry. Magnesium-based alloys are not the first object of attention of scientists working on the light metals. Professor satisfied with the result achieved:

This is a very important and timely discovery … There is a great demand for magnesium alloys, which will be used everywhere, from portable electronics to air and land transport.

Magnesium alloys have met a warm reception in the industry, but their use has been limited by high susceptibility to corrosion. Currently, scientists are searching for ways to reduce costs and improve efficiency. In particular, they have developed a three-dimensional graphene to replace platinum in solar cells. Weight reduction devices and transport is also an important step towards reducing costs.
