本研究的第一部分中，設計了不同Al跟Ti含量的AlxCo1.5CrFeNi1.5Tiy系列高熵合金，並針對其組成相與微結構做研究。文中探討此系列合金之黏著磨耗行為與機制，並與常見的耐磨鋼材，SUJ2軸承鋼及SKH51高速鋼做比較。結果顯示Al跟Ti的含量會顯著地影響合金的組成相與微結構，特別是其中堅硬的η-(Ni, Co)3Ti相之數量與形貌。Al0.2Co1.5CrFeNi1.5Ti合金在相近的硬度表現下，其磨耗阻抗至少比常見的耐磨鋼材好一倍以上。這些高熵合金之所以會有如此傑出的磨耗阻抗主要是因為其優異的抗氧化性與抗高溫軟化性質。
在第二部分中，本研究使用Al0.3CrFe1.5MnNi0.5高熵合金，展示了一種利用在靠近表層區域局部析出的表面硬化處理方法。這種表面析出硬化法製程簡單，只需要在大氣下進行一般的時效處理，並且適用於複雜形狀的物體。實驗的結果顯示，經過此表面硬化的Al0.3CrFe1.5MnNi0.5高熵合金，其磨耗阻抗至少增加了百分之五十，並且只有些許的彎曲韌性損失。跟常見的SUJ2軸承鋼與SKD61熱作工具鋼比起來，此表面硬化處裡過的Al0.3CrFe1.5MnNi0.5合金有著更好的機械性質組合。
