It is possible to add a small percentage of oxygen to an atmosphere of argon in a sputtering chamber from which air has been evacuated to sputter etch gold, palladium and platinum selectively with respect to metals such as titanium and nickel. (See U.S. Patents 3,856,648; 3,836,456; and 3,808,108.)
