by cathode polarization tests and nickel electrodeposition experiments. The experimental results show that the addition of boric acid can increase the cathode polarization while SDS can decrease the cathode polarization. Both boric acid and SDS are useful to eliminate the pitting on nickel deposits and improve the morphology of surface. Good deposit morphology with rare pitting and high current efficiency......

potential of NZK is much lower than that of AZ91D indicated by the open circuit potential measurement. The cyclic polarization curves show that NZK alloy has higher pitting corrosion resistance than AZ91D. Key words: AZ91D Mg alloy; Mg-RE alloy; corrosion behavior; cyclic polarization  ......
spectroscopy (EIS) and polarization curves of the testing alloys in simulated body fluid (SBF). The results show that corrosion resistance of TNTZ alloy is improved by adding Y2O3. The corrosion...; corrosion behavior; Y2O3; polarization curve; SBF 医用金属材料由于具有较高的屈服强度,断裂极限和疲劳极限等力学性能以及优异的抗摩擦磨损性能等,成为目前医学临床应用最广泛的承力植入材料[1-2].然而,自金属被用作人体修复材料以来,腐蚀问题长期困扰着合金的安全服役[3].新型β型钛合金由于其表面可自发形成钝化膜,从而表现出较高的稳定性及耐腐蚀性,并以其优良的生物相容......
