利用電化學技術研究外科整形術上的數種金屬材料在鹽水 (0.15M) 中的耐蝕性，研究的材料包括純金屬鈦、鉭、鈮及合金，例如含鋁之不銹鋼，鑄及鍛之鈷－鉻基合金，以及有限之鈦合金。由實驗結果顯示，316L不銹鋼較cast Vitallium易於形成小孔腐蝕，窄縫腐蝕及均勻腐蝕，這兩種合金是目前在外科整形術上應用最廣泛的材料。從已發表有關這兩種合金在臨床試驗上所發生缺陷，相當鈷－鉻基合金H.S.25今後似應接廣泛採用，因為它具有優越的耐蝕性，降伏強度及延性。
Electrochemical techniques were employed in measuring the corrosion resistance of a number of orthopedic implant metals in isotonic salt solution (0.15M). Pure metals such as Ti, Ta, Nb, and molybdenum stainless steels, cast and wrought cobalt-chromium base alloys as well as a limited number of wrought titanium alloys were studied. The results obtained indicate that of the two alloys now most widely used in orthopedic surgery, namely 316L stainless steel and cast Vitallium (H.S.21), the former shows a higher tendency to pit, crevice, and general corrosion than the latter. In view of published and unpublished clinical shortcomings of both alloys it appears that the wrought cobalt-chromium base alloy H.S.25 deserves more extensive application than it has heretofore received, due to its superior corrosion resistance, yield strength, and ductility.
