METHOD FOR EVALUATING CORROSION RESISTANCE OF METALLIC MATERIAL, METHOD FOR PREDICTING CORROSION LIFE THEREOF, METALLIC MATERIAL, METHOD FOR DESIGNING THEREOF, AND METHOD FOR MANUFACTURING THEREOF

摘要

PROBLEM TO BE SOLVED: To provide a method for evaluating the corrosion resistance of a metallic material simulating an actual environment, a method for predicting corrosion life thereof, the metallic material, a method for designing thereof, and a method for manufacturing thereof.;SOLUTION: The method evaluates the corrosive of the metallic material by repeatedly performing a process consisting of an (A) process and a (B) process a plurality of times. Therein, the (A) process for adhering salinity including a chloride ion to the surface of the metallic material and the (B) process for performing an operation cycle consisting of a drying process and a wetting process set by stepwise varying temperature and relative humidity to the metallic material, once or a plurality of times. The (A) process requires within 10 minutes.;COPYRIGHT: (C)2004,JPO
