Iron chromium electroplating

WebThe regenerated plating solution was used to electroplate a chromium deposit in a 500-mL rectangular plating tank. Sulfuric acid was added to adjust the CrO 3 /H 2 SO 4 ratio to 100:1. The thermostatically controlled tank contains two square lead plates (25 cm2) as anodes, placed opposite each other. Web2001. ASTM B650 [affil. link] is the specification for chromium electroplating on iron and steel, and will have the information on classes, etc. Also worth reading is ASTM B177 [affil. link], the Standard Guide of Chromium Electroplating on Steel for Engineering Use.
