Patentiert im Deutschen Reiche vom 20. Juni 1918 ab.Patented in the German Empire on June 20, 1918.
Nach der Erfindung wird eine mittelstarke Verbleiung von Eisen und Stahl dadurch erzielt, daß nian den bekannten Bleikontaktbädern oder anderen sauren oder alkalischen Bleilösungen, welche einen Überschuss an freier Säure bzw. freiem Alkali enthalten, außer den Kontaktmetallen Bleisuperoxyd alsDepolisator hinzufügt. Dieses gibt bei seiner Zersetzung Sauerstoff ab, der mit dem am Arbeitsstück auftretenden Wasserstoff wahrscheinlich Wasser bildet und so die Bildung eines glatten Niederschlages günstig beeinflußt.According to the invention, a moderate lead of iron and steel is achieved by that nian the well-known lead contact baths or other acidic or alkaline lead solutions, which have an excess contain free acid or free alkali, in addition to the contact metals, lead peroxide as a depoliser adds. When it decomposes, this releases oxygen, which with that on the workpiece occurring hydrogen probably forms water and so the formation of a smooth Precipitation favorably influenced.
