“Everyone in the industry has been waiting for this discovery. This is a paradigm shift in the field of high-temperature oxidation. We are now establishing new principles for understanding the degradation mechanisms in this class of materials at very high temperatures.” Many current and future technologies require alloys that can withstand high temperatures without corroding.
Self-healing metal oxides could protect against corrosion. Researchers find an ultrathin layer of aluminum oxide, though solid, can flow like a liquid instead of cracking. Researchers have found that a solid oxide protective coating for metals can, when applied in sufficiently thin layers, deform as if it were a liquid, filling any cracks and gaps
