| Abstract(J) | 自動車を海岸地域に保管する際，排気系ステンレス部品に美観を損なう特異な錆が発生することがある．本研究ではその再現試験手法を確立し，発錆機構を明確にした．さらに屋外暴露試験を時期毎に実施することにより，腐食の主因子及び各ステンレス材の腐食変化を調査し，腐食予測方法を構築した． Translation |
| Abstract(E) | When vehicles are pooled in a coastal area, specific disfiguring rust may be generated on exhaust parts made of stainless steel. This study is to build the simulation technique and to clarify the mechanism. This result indicates that the corrosion morphology forms by exhaust heat and magnesium chloride (MgCl2). Furthermore, we conducted seasonal outdoor exposure tests to investigate the main environmental corrosion factors and the corrosion transition behavior of each stainless steel, and built a corrosion prediction method. |
