鎂鋰合金的高比強度與優秀的延展性勢必將使其成為未來輕金屬中的主流，
此研究對 LZ91 的腐蝕進行了一系列的探討，然而若想更深入了解鎂鋰合金的腐蝕 行為則以下是兩點可行的方向：
1. 測試不同雜質或合金元素對鎂鋰合金腐蝕的影響，特別是於本研究之 LZ91 腐
蝕產物中包含的一些雜質／合金元素（如鐵、錳、鈣等）。
2. 確認是否雙相效應不明顯的情況為大部分鎂鋰合金中的共通現象，並可以理論、
計算等方式輔助驗證，若此結果為真則可以許多純鎂研究中的結果來解釋、預 測鎂鋰合金的腐蝕表現。
防蝕處理方面，鈦酸鹽化成為一較少被討論的化成系統，然而經本研究證實其 可有效延緩 LZ91 的腐蝕，加上經長時間的嚴苛浸泡腐蝕後證實二氧化鈦／二氧化 矽層仍存在於 LZ91 表面，故以二氧化鈦的高穩定性嘗試鈍化鎂合金乃一可行之 道。然而此鈦酸鹽化成系統仍存在許多問題，若想進一步增進防蝕能力、推廣此系 統則可以下列出的三點方向思考：
1. 四氯化鈦溶液易揮發反應，穩定性不佳，若能更換產生二氧化鈦的反應物則可 解決此一問題。
2. 防止氫氧化鎂的生成，使用非水溶液系統或許是一個方向，然若如此則必須考 慮六氟矽酸與四氯化鈦於非水溶液中的反應問題，另外化成液溫度、反應物濃 度等控制變因也可能略為改善脫水裂紋。
3. 氟化鎂並非不可或缺的，鈦酸鹽化成膜中主要的抗蝕能力來自二氧化鈦／二 氧化矽，故可考慮不使用含氟的反應物以增加化成液的安全性、環保性。
