A method of anodizing non-stainless steel, wherein a non-stainless steel object is connected to a positive terminal of a power supply, a counter electrode or vessel is connected to a negative terminal of the power supply, the non-stainless steel object and counter electrode are placed into a solution of NaOH, and a voltage is applied across the terminals to anodize the non-stainless steel object by forming an adherent blue-black or semi-adherent dichroic, colored oxide coating thereon. |
