[Dissolution of alloy components from Ni/Cr base alloys by bacterial leaching]. / Die Auslösung von Legierungsbestandteilen aus Ni/Cr-Legierungen durch bakterielle Laugung.

The method of bacterial leaching of non precious dental alloys represents a useful completion of the method arsenal of biological investigations. In contrast to other well known methods it allows to point out small differences in corrosion resistance between alloys of the same type in a biologic system.
