In reference to http://cr4.globalspec.com/thread/4671/Ceramic-Coating-Insulation.
We have technology of the covering of aluminum by heavy-duty isolating coating.
Hardness of the coating is 9,5-9,6 on Mohs (diamond is 10,0) or 3000 - 4000 kg/мм2 on Vickers.
Thickness of the coating is 50-500 micron.
Electric insulation of the coating is 1,5 – 3,0 kV as a rule.
Temperature of destruction is more than 2500K.
The chemical formula is Al2O3.
