Except the steel in question is an austenitic stainless so the oxide layer would contain nickel and chromium oxides.wim said:In simple terms, "anodizing" means increasing the natural oxidation layer of a metal. If you would anodize steel, you would increase the natural oxidation layer of steel, which is rust. No go.
Technically correct, but I hesitate to use the term "anodizing" for steels of any kind. The process is just too different.Mark Kelly said:As it happens you can anodise stainless steel and the oxide layer is black in colour due to the chromium oxides. I do not believe that this is the process the spoke makers use, however, as the surface layer on anodised stainless is notoriously easily damaged.
