Discovery of ‘stainless magnesium’ could herald transport revolution | UNSW Newsroom: "‘This is the first magnesium-lithium alloy to stop corrosion from irreversibly eating into the alloy, as the balance of elements interacts with ambient air to form a surface layer which, even if scraped off repeatedly, rapidly reforms to create reliable and durable protection,” Professor Michael Ferry said.
The UNSW team partnered with scientists on the Powder Diffraction (PD) beamline at the Australian Synchrotron, to confirm that the alloy contains a unique nanostructure that enables the formation of a protective surface film.
The researchers have now turned their attention to investigating the molecular composition of the underlying alloy and the carbonate-rich surface film, to understand how the corrosion process is impeded in this ‘stainless magnesium’."
