A process for removing titanium from a device is disclosed. The titanium is etched at a controllable rate. The etchant oxidizes the titanium, and the oxidized titanium forms a complex in the etchant. When the concentration of this complex in the etchant nears its solubility limit, it precipitates and forms a film on the titanium metal surface.

The mechanically triggered interactions in the Ti–C and Hf–C systems performed in a high-energy planetary ball mill are studied. The formation of carbides (TiC and HfC) in the course of mechanochemical synthesis at the different stages is followed by both conventional and synchrotron X-ray diffraction analyses and high-resolution scanning and transmission electron microscopy. The …
