Abstract

265,833. Appel, R. May 17, 1926. Addition to 259,118. Chromium, depositing; preparing surfaces. - The process of the parent Specification is modified by increase of the proportion of sodium sulphate to 0.5-1.0 gms per litre of bath liquid. Sodium sulphate may be replaced by an equal proportion of another salt, e.g. potassium sulphate or bisulphate, magnesium sulphate, neutral or acid phosphates, or like substances. The added substances may also contain inorganic and organic acids. The articles may be polished before plating; subsequent plating is then unnecessary.
