不□鋼經電解拋光處理後表面奈米陣列之研究

Abstract

本次實驗藉由電解拋光處理的方法，成功地在商用之304不□鋼（FCC結構）上獲得奈米級六角形陣列結構，且首次發現在430不□鋼（BCC結構）上，亦可產生奈米規則圖案，由此可知陣列的形成機制並不受基材純度及晶體結構影響，故以往的理論模型不再受用，而此現象可由新的電驅動對流理論，成功地解釋並說明此規則圖案的成因及機制。

In this study, the nano array pattern on the commercial 304 stainless steel (FCC structure) be gotten successfully by electropolishing. And it was firstly observed the nanoscopic regular morphology on the 430 stainless steel (BCC structure). According to the results, the mechanism of nano array formation on the stainless steels does not depend on the purity or crystal structure of the substructure. Therefore, the past theories about nano array formation are discarded in this case. However, the phenomenon can be explained fully by the latest theory of the electroconvection.
