Abstract

693,292. Electrolytic polishing. OFFICE NATIONAL D'ETUDES ET DE RECHERCHES AERONAUTIQUES (O.N.E.R.A.). July 21, 1950 [Aug. 5, 1949; Dec. 6, 1949; June 27, 1950], No. 18288/50. Drawings to Specification. Class 41. [Also in Group II] A chromium coating on an object of nickel, cobalt, molybdenum or tungsten or on a ferrous object, produced by exposure to chromium fluoride vapour (see Group II), is anodically polished in a path containing perchloric and acetic acids.
