Our process begins with a pre wash surface preparation to remove any contaminants such as machining oils. Such contaminants can cause inconsistencies in the compound layer thickness as well as affect the aesthetics of a finished work piece. The work pieces are preheated to 700°F, immersed in a liquid salt bath at 1055°F where they're nitrocarburized. Depending on customer requirements, the work pieces are immersed in lower temperature liquid salt bath where they're quenched to 700°F and black oxidized. Finally the work pieces are quenched in water then rinsed. Post processing may include polishing and/or oiling for aesthetics and/or additional engineering properties.
