PROCEDE DE PREPARATION DE LA SURFACE DE PIECES EN URANIUM OU EN ALLIAGE A BASE D'URANIUM

摘要

Process for the preparation of the surface of a uranium or uranium alloy part. It comprises a stage of chemically etching the surface of the uranium or uranium alloy part by means of a solution of nickel chloride and hydrochloric acid. The etching solution may also contain hydrofluoric acid. The nickel-coated uranium or uranium alloy parts can be used as shielding or ballasting members in a marine atmosphere.
