Low ph cause corrosion
WebAs expected, the lead solubility of corrosion scale generally decreased as pH increased; whereas dissolution of other accumulated metals present in the corrosion scale followed … WebThis dangerous form of corrosion can cause a structure to fail despite a relatively low loss of metal. Crevice Corrosion. This form of corrosion occurs in areas where oxygen is restricted such as under washers or bolt heads. This localised corrosion usually results from a difference in the ion concentration between two areas of metal.
