Title: Development of a passivated stainless steel surface

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.

Surface modified stainless steels for PEM fuel cell bipolar plates

Patent Brady, Michael P [Oak Ridge, TN]; Wang, Heli [Littleton, CO]; Turner, John A [Littleton, CO]

A nitridation treated stainless steel article (such as a bipolar plate for a proton exchange membrane fuel cell) having lower interfacial contact electrical resistance and better corrosion resistance than an untreated stainless steel article is disclosed. The treated stainless steel article has a surface layer including nitrogen-modified chromium-base oxide and precipitates of chromium nitride formed during nitridation wherein oxygen is present in the surface layer at a greater concentration than nitrogen. The surface layer may further include precipitates of titanium nitride and/or aluminum oxide. The surface layer in the treated article is chemically heterogeneous surface rather than a uniform ormore » « less
