抄録

Spiral patterns were often observed during chemical polishing of α-brass with phosphoric, acetic and nitric acid solution. Several experiments were performed in order to clarify their formation mechanism. It is confirmed that these patterns are quite similar to the ones formed on aluminium surface by electropolishing reported previously. It is concluded that they represent growth spiral patterns of cuprous oxide deposited on specimen surface in the course of chemical polishing. A small addition of chloric ions proved to be very effective to prevent their formation and to get good polishing. They are supposed to act as catalyser to carry away excess metallic ions.
