cathodic protection(protection of ferrous metals against electrolysis by the attachment of sacrificial anodes. Also called electrolytic protection. RHWD. a technique for protecting metal structures, such as steel ships and pipelines, from electrolytic corrosion by making the structure the cathode in a cell, either by applying an electromotive force directly or by putting it into contact with a more electropositive metal. Collins Alexander Demidov; катодная защита - это один из видов электрохимической защиты, в числе которых также протекторная и дренажня защита. см.http://transenergostroy.ru/blog/elektrohimicheskaya_zashhita_truboprovodov_ot_korrozii.html?ysclid=l6k7shrgf1304516300Mixer)
