Chemical Passivation Treatments
While not offering all of the benefits of electropolishing, chemical passivation will improve the corrosion resistance of stainless steel. The presence of exogenous surface contaminates may disrupt the formation of stainless steels' naturally corrosion resistant surface layer. Surface contaminants, including grease, dirt, iron, and other metallic particles are inherent to the metal fabrication process. During a chemical passivation treatment, the surface of a part is chemically treated by a mild oxidant. The passivation treatment removes free iron and other foreign contaminants and promotes the formation of a chromium-rich corrosion resistant layer.
Harrison Electropolishing has performed chemical passivation treatments with excellent results since 1980. We have the capacity to passivate stainless steel components of all sizes at our facility or a jobsite anywhere in the world. Harrison Electropolishing will perform chemical passivation treatments in compliance with ASTM specifications or your industry or company specific chemical passivation standard.
