Abstract
Die Erfindung betrifft ein Verfahren zum Aufbringen met allischer Überzüge auf metallische Werkstücke durch mech anisch-chemisches Behandeln der Werkstücke in einem in erte Prallkörper enthaltenen Bad, indem eine Relativbewegung zwischen Werkstücken und Prallkörpern bzw. Bad erzeugt wird, und dem ein Promotor und das den Überzug bildende Metall beigegeben werden, wobei, um zu vermeiden, daß Metalle in Lösung gehen und eine damit ver bundene Wasserstoffentwicklung auftritt, spätestens vor und/oder während der Zugabe des den Überzug bildenden Metalls eine Säurezugabe unter Verwendung mindestens einer wasserlöslichen organischen Carbonsäure oder unter Verwendung einer Kombination aus mindestens einer wasserlöslichen organischen Carbonsäure und/oder deren Salze mit mindestens einer Mineralsäure in einer solchen Menge erfolgt, daß der pH-Wert des Bades zu Beginn der Metallaufbringung etwa im Bereich größer 2,5 - 4,5 und an ihrem Ende etwa im Bereich von 3 - 7 liegt. The invention relates to a method for applying met allic coatings on metallic workpieces by mech anicochemical treatment of the workpieces in one erte impact body contained bath by a Relative movement between workpieces and impact bodies or bath is generated, and the one promoter and the Plating-forming metal can be added, taking to avoid that metals go into solution and ver bound hydrogen evolution occurs, at the latest before and / or during the addition of the coating Metal using an acid addition at least a water-soluble organic carboxylic acid or under Use a combination of at least one water-soluble organic carboxylic acid and / or their Salts with at least one mineral acid in one Quantity occurs that the pH of the bath at the beginning of the Metal application approximately in the range greater than 2.5 - 4.5 and on their end is in the range of 3-7.
