Black oxide finishing for everyday residential use

2002

I am an architect interested in the variegated aesthetic of the black oxide process for a plate steel handrail I will be fabricating for a residence I am designing. Painting and other attempts at "imitating" this look have proven unsatisfactory. I have only a cursory knowledge of metallurgy. Is it possible/necessary to apply a clear coat after the finishing (will the black oxide rub off through wear), that will retain the appearance for a degree of longevity and keep the finish inert?

Thank You.

Black oxide has very little corrosion resistance, and most of what little you see is from rust preventative oils used with it. If you want the look of black oxide on a handrail, I don't see an alternative to clear coating it.

Have you thought about black nickel or chrome?
