HTC's One S -- launched earlier this year at Mobile World Congress -- features a nifty ceramic-like finish that is achieved using micro arc oxidation. We've of course heard about the process and been treated to the details of the treatment but had yet to see it translated for our eyes to behold. HTC has a stand set up at CTIA detailing the steps from blank lump of aluminum to the finished HTC One S product with its lovely smooth black shell. Have a quick peek at the gallery below and then on to the video tour of the process steps from stamping to grinding to 10,000-volt shock. Plasma!
