    • ‘A full-contact adhesive segregates the materials so there is no chance of a galvanic reaction, while self-piercing rivets provide extra holding power in peel-prone areas.’
    • ‘Blistering paint on metal components may be the first sign of galvanic corrosion, followed by a white powdery buildup on the aluminum surface and finally deep pitting that leaves the aluminum weak and porous.’
    • ‘The technique, known as galvanic vestibular stimulation, unbalances a person so that they automatically veer left or right in an attempt to rebalance themselves.’
    • ‘Since titanium and titanium alloys are very resistant to corrosion, the filler metal should be selected carefully to avoid galvanic corrosion.’
    • ‘Because the use of dissimilar metals is avoided, the possibility of galvanic corrosion is minimized.’
    • ‘Contact of differing metals can cause a galvanic reaction that produces rust and deterioration.’
    • ‘A rust or a galvanic cell reaction could develop at the juncture between the screw and the stud.’
