.... The fracture surfaces were coated with zinc oxide. It was concluded that the failure resulted from improper repairs and/or adjustments, including the use of a cosmetic zinc oxide cream as a lubricant. The cream initiated deterioration of the originally ductile plastic, causing it to become brittle and fragile...

... ]. At room temperature, the zinc’s anodic protection is gradually decreased by insulating corrosion products, i.e., zinc oxide, zinc carbonate, etc. It has even been reported that a slight reversal of polarity can occur, i.e., the remaining zinc coating is the cathode and the exposed steel is now the anode...
