Abstract Scope |
A new mill product conditioning process has been developed and patented by MetCon; arguably the most dramatic cost reduction for production of metallic titanium in 30 years. The novel electrochemical process has been industrially commercialized for titanium mill products as an alternative to midwest grinding or machining techniques. The “MetCon Process” involves submerging the metal workpiece in an aqueous electrolyte of carboxylic acid + a fluoride salt while connected to a DC power supply, immersing the opposing electrode of the power supply in the bath, and applying current across the bath. 10% to greater than 15% more finished mill product from starting ingot is generated due to yield improvements compared to traditional conditioning. With minor changes, the technology can additionally be used as a green alternative to traditional hydrofluoric plus nitric acid pickling, addressing environmental and occupational hazards. |
