Abstract
A multi-step Q-passivation method for stainless steel is described. The method includes a first high voltage electropolishing step followed by as separate low voltage chromium enhancement step. The method can also include a vacuum heat treatment step that utilizes a cyclic ramp-up period so as to maintain a relatively low pressure and low temperature throughout the step. The method can also include a controlled oxidation step during which the surface is contacted with an oxygen/inert gas mixture at low oxygen partial pressure.
