本研究以無電鍍法析鍍鎳鉬磷合金鍍層，藉由鎳磷的抗腐蝕性以及鉬的潤滑性兼具的無電鍍合金鍍層再進一步進行真空熱處理，以提高鍍膜其硬度和耐磨耗性質。
本次以AA5083為基材，AA5083 鋁合金擁有低密度、耐腐蝕性佳、高強度比等特色，為加工硬化性鋁合金，並常使用在工業用途以及交通工具上。
研究階段分為：
1. 在AA5083上析鍍無電鍍Ni-Mo-P以及Ni-P鍍層。
2. 在不同溫度以及時間變數進行真空熱處理。
3. 進行微硬度測試、磨耗試驗、電化學腐蝕來判斷其優劣。
真空熱處理雖然能提高無電鍍Ni-P的硬度，但在本研究中發現，在400 進行真空熱處理發現AA5083析鍍無電鍍Ni-P和Ni-Mo-P鍍層皆出現裂紋。
無電鍍Ni-Mo-P 在pH6.8 60 min 83 5 的情況下能均勻附著在AA5083上，在Ni-Mo-P 合金鍍層在真空熱處理200 15min 的情況下其抗腐蝕能力明顯優於其他熱處理情況以及Ni-P鍍層。

The AA5083 aluminum alloy is widely used for many application in automotive , marine , aircraft body sheet due to its excellent combination of strength, corrosion resistance .
Research step :

2. Different temperature and time variables in vacuum heat treatment.
3. The coatings are deposited for characterizations of microhardness , wear and corrosion test .
Coating''s hard is strength by vacuum heat treatment , but find some pits on coatings surface , this properties not conducive in corrosion test. Electroless Ni-Mo-P were deposited in pH 6.8 60 min 83 5 . Ni-Mo-P coatings due to its excellent combination of corrosion resistance in 200 15min vacuum heat treatment.
