This is a process similar to anodising, but using greater potentials so microscopic sparking occurs all over the metal surface, resulting in a thick layer of oxide can be produced on a metal surface. The coating is from the conversion of the metal into the oxide, which therefore adheres well to the substrate. The oxide can be very hard and resistant to abrasion or in some cases corrosion. This movie was taken at MISiS, National University of Science and Technology, Moscow, Russian Federation. The technology was invented in Russia. One of the initial applications was in the Mir Space Station. http://www.msm.cam.ac.uk/phase-trans
