Aluminium gets ceramic surface

You’ve bought a good smart phone, and then it slides out of your pocket. Of course it falls not in the grass but on the sidewalk. Should have bought that protective case at once.

Well, it seems you don’t need any protective case when the cell phone body has been treated with micro arc oxidation. HTC applies 10.000 volts of energy to aircraft 6000 series aluminium. The result is a ceramic finish that makes your phone very durable.
