METHOD FOR TESTING ACCELERATED CORROSION OF STEEL MATERIAL IN ATMOSPHERIC ENVIRONMENT

摘要

PROBLEM TO BE SOLVED: To provide a method for testing the accelerated corrosion of a steel material in an atmospheric environment.;SOLUTION: The method for testing the accelerated corrosion of the steel material in the atmospheric environment is such that, the rust preliminarily adhered to the surface to be tested of a corrosion test piece is set; γ-FeOOH particles and/or Fe₃O₄ particles are adhered at a total amount of 10 g/m² or more and 100 g/m² or less; a continuous temperature change is subsequently applied to the test piece, to perform dew condensation and drying so as to set 24 Hr as one cycle; and a plurality of cycles are repeated, to evaluate the corrosion resistance of the steel material.;COPYRIGHT: (C)2010,JPO&INPIT
