| Abstract(J) | 自動車における防錆性能は，主に電着塗膜が担っているが，市場の塩水負荷により経時で塗膜が劣化することで腐食は始まる．これまで自動車の錆寿命は, 市場の錆状態から予測してきたが, 今回，交流インピーダンス法による電気化学解析によって塗膜劣化のメカニズムを明確にし, 計算科学による寿命予測技術を確立した． Translation |
| Abstract(E) | The corrosion prevention performance of vehicle is mainly responsible for the ED-coating, and automotive corrosion is occurred by degradation of the ED-coating film due to salt water stress in the market. Until now, we have predicted the lifespan of vehicle in various environments from market research about rust rank. However, this time, alternating impedance method established a technology for predicting the lifespan of ED-coating using computational science and it elucidated the mechanism of degradation of paint film. |
