Abstract
New alloys highly resistant to corrosion by concentrated acid and having excellent adhering properties when coated on stainless steel are formed of 60 to 90 atomic percent tantalum or tungsten, with the remainder being iron, chromium and nickel in the proportions found in stainless steel, e.g., 304L stainless steel. They may be formed in situ on the surface to be coated by sputter deposition, using a sputter target which is part tungsten or tantalum, and part stainless steel.
