Based on damage research and corrosion experiments, an attempt is made to systematize failures of heat-exchanger lubes through different kinds of corrosion (with and without mechanical loading) from the cooling-water side. Various countermeasures are offered to prevent corrosion of the tubes. Since the stability of the protective layer is the main barrier against corrosive attack, indications are given of ways to improve these layers on copper alloys and to determine their stability.
