Abstract — The contacts of a tin–lead solder (
OC 61) with copper, brass and nickel in various types of disinfectants are investigated as galvanic couples where the solder always functions as the anode. The maximum relative increase in the corrosion rate is observed in a weakly alkaline hembar solution (guanidine-based biocidic polymer compound). The active oxidizers contained in delaxon and chlorantoin solutions can decompose due to their reduction at the cathodes of the couples.
