"lightweight magnesium can replace heavy steel/ titanium substrate, but its ceramic synthesis requires >1,300°K damaging it... overcome applying coating by combining steam with solvothermal growth at 453°K... ultralow corrosion, high electrical conductivity, remains chemically stable even after 200 hours acidic immersion... fuel cells, clean energy systems, and aerospace applications"
