Help – Mechanical polishing of stainless steel 316L
Thread Content
This post was last edited by jia717 on 2010-11-23 20:07. Why does the brightness decrease after mechanically polishing stainless steel 316L and then electropolishing it? Are the scratches particularly obvious?
It’s simple – the construction wasn’t done properly; the technique itself is fine
Mechanical polishing allows the protruding parts of the workpiece to \"flow\" and fill in the recessed areas, thereby creating a layer on the metal surface composed of a mixture of metal, oxides, and polishing particle debris – what is known as a passivation layer. During the electrolytic process, the dissolution rate of the protruding parts is higher than that of the recessed areas; as this debris dissolves and falls off, any existing scratches become visible. As for brightness, roughness is directly proportional to brightness. It is recommended to use passivators and surface activators during mechanical polishing, as this yields significant results. I’m very happy to discuss everything related to polishing with friends, 13898980209
