摘要： PROBLEM TO BE SOLVED: To provide a corrosion resistance evaluation method for a surface treated steel sheet, having a high correlation with corrosion of an actual automobile side sill part. SOLUTION: A steel sheet layered part is formed by applying one or more kinds processing out of deep drawing, draw-beading and plane sliding to the surface treated steel sheet. and by layering the surface treated steel sheets of different or same kinds after applying the processing. Then, the steel sheet formed with the steel sheet layered part is supplied as a test piece to a corrosive environment so as to evaluate corrosion resistance. The steel sheet layered part is preferably formed therein by resistance-welding the surface treated steel sheets of different or same kinds to be joined. The steel sheet layered part is formed to simulate actual automobile structure, and is preferably chemical-conversion-treated and electro-deposition-coated to serve as the test piece, and the test piece is subjected to the corrosive environment so as to evaluate the corrosion resistance. The corrosion test is carried out, for example, by a SAE J2334 120 cycle. COPYRIGHT: (C)2009,JPO&INPIT
