Abstract

"PROCESSO DE PREVENçãO DE CORROSãO GALV‰NICA DE UMA SUPERFìCIE, E, TROCADOR DE CALOR". Trata-se de um processo para reduzir a corrosão galvânica de metais diferentes em contato uns com outros, em que a superfície exposta do metal menos nobre é revestido com um metal mais compatível galvanicamente com o metal menos nobre."PROCESS FOR PREVENTION OF GALVANIC CORROSION OF A SURFACE AND HEAT EXCHANGER". It is a process to reduce galvanic corrosion of different metals in contact with each other, in which the exposed surface of the less noble metal is coated with a metal more galvanically compatible with the less noble metal.
