Abstract: A method for vacuum heat treating Nb, such as is used in superconducting radio frequency cavities, to engineer the interstitial oxygen profile with depth into the surface to conveniently optimize the low- temperature rf surface resistance of the material. An example application is heating of 1.3 GHz accelerating structures between 250-400 °C to achieve a very high quality factor of 5x1010 at 2.0 K. With data supplied by secondary ion mass spectrometry measurements, application of oxide decomposition and oxygen diffusion theory was applied to quantify previously unknown parameters crucial in achieving the oxygen alloy concentration profiles required to optimize the rf surface resistance. RF measurements of vacuum heat treated Nb superconducting radio frequency cavities confirmed the minimized surface resistance (higher Qo) previously expected only from 800 °C diffusive alloying with nitrogen.

Abstract: A method for treating (200) a surface of an implant (100), the method involves cleaning (201) the surface of an implant (100). Annealing (203) the cleaned implant (100) in a furnace at a temperature ranging from 1000°C to 1200°C in the presence of an inert gas. Descaling (205) of the annealed implant (100) using one or more descaling agents or solutions to remove debris. Surface treating the descaled implant (100) using one or more reagents. The reagent reacts with the metal particles on the surface of the implant (100) to form an oxide layer on the implant (100) and coating (211) the treated surface of the implant with a coating layer (101).
