不同腐蝕條件對316L不鏽鋼表面產生多孔性氧化層之影響
The Effects of Various Corrosion Conditions on The 316L Stainless Steel Surface Porous Oxide Layer
摘要
本研究針對316L不鏽鋼板材施以低溫浸泡腐蝕、珠擊浸泡腐蝕以及電化學腐蝕三種不同表面處理製程，觀察不同處理條件下316L不鏽鋼板材表面形貌的改變與板材表面層中機械性質變化之情形。腐蝕處理後的表面形貌變化是利用掃描式電子顯微術 (Scanning Electron Microscopy) 、拉曼散射光譜術 (Raman Scattering Spectroscopy) 及薄膜厚度輪廓測試術 (α-step) 來觀察及分析，機械性質變化是利用洛氏硬度計 (HR15N) 來分析，成骨細胞 (human osteoblast) 貼附測試是在316L板材表面以劉氏染色法染色後利用金相光學顯微術 (Metallographic Optical Microscopy)進行觀察，結果發現：低溫浸泡腐蝕、表面珠擊腐蝕製程的板材細胞貼附成果較差，電化學腐蝕在高電流密度、低濃度腐蝕液可以獲得均勻腐蝕的表面形貌，成骨細胞貼附測試結果顯示最佳參數下細胞貼附較其他參數緻密。

The 316L stainless steel plates subjected to low temperature for immersion corrosion, shot peening corrosion and electrochemical corrosion attack three different surface treatment processes. Observed under different treatment conditions 316L stainless steel sheet and plate surface morphology changes in the surface layer changes in the microstructure and mechanical property changes. Corrosion of the surface morphology changes after treatment is the use of Scanning Electron Microscope ( SEM ) , Raman scattering Spectrometer ( Raman ) and the film thickness profile tester ( α-step ) to observe and analyze. Changes in mechanical properties is the use of Rockwell Hardness Tester ( HR15N ) to analyze. Cell adhesion test was dying the surface of 316L stainless steel by Liu staining method and observing by Metallographic Optical Microscopy ( MOM ). The results showed that: low temperature for immersion corrosion, shot peening corrosion of the surface of cell adhesion process poor results. Electrochemical corrosion in the high current density, low concentration of etching solution can be obtained on the surface morphology of corrosion. Cell adhesion test shows that the optimum parameter of cell adhesion denser than other parameters.
