Microbial corrosion method and cathodic protection methods

摘要

PROBLEM TO BE SOLVED: To provide a method of preventing bacterial corrosion which can substantially reduce the amperage necessary for corrosion protection.;SOLUTION: A method of preventing bacterial corrosion is for preventing bacterial corrosion of a metal material arranged in one of a water environment in which bacteria are present and a soil environment containing moisture in which bacteria are present and comprises applying a negative voltage in a voltage window range where practically no electric current flows in response to the kind of a metal material to a metal material arranged in one of a water environment in which bacteria are present and a soil environment containing moisture in which bacteria are present.;COPYRIGHT: (C)2014,JPO&INPIT
