HTC Shows Off Micro Arc Oxidation Process, Claims One S Won’t Even Need a Case
Who could forget the spectacular metal HTC is using to make its upcoming One S Ice Cream Sandwich packing smartphone? As a refresher, the ceramic effect of its metal unibody shell is created by using a process known as micro arc oxidation. Not familiar with micro arc oxidation? Not to worry, as curious minds can now see how HTC makes it all happen in their latest YouTube video installment. In the video HTC claims that the shell, which is made from aircraft-grade aluminium, gets hit with a staggering “10,000 volts of energy,” causing a reaction that instantly results in the black color and smooth texture.
HTC is quick to point out that process is a treatment to the actual metal itself, versus a mere finish on top of it. Additionally, HTC claims the metal to be five-times stronger as a result of the micro arc oxidation process. Don’t just take our word for it, check out the cool zapping video demo above for yourself.
Micro-arc Oxidation can form ceramic oxide coating with ultra high hardness due to its crytalline structure.
I find the following link with Micro-arc Oxidation technique and they also can do black Ceramic:
