    摘要:

    利用離子束增強沉積技術在鈦合金表面制備CrN硬質抗磨層和CuNiln固體潤滑膜層。通過電化學測試技術對比研究了膜層和鈦合金基材在含Cl介質中的抗蝕性能和接觸腐蝕敏感性，利用高溫靜態(tài)氧化方法評價了膜層的抗氧化性能。結果表明：(1)CuNiln膜層耐電化學腐蝕性能和抗氧化性能顯著優(yōu)于Cu，在含Cl介質中與鈦合金接觸相容。(2)在含Cl水溶液中，CrN膜層耐蝕性好，與鈦合金接觸相容；在HCl HF混合酸中，CrN膜耐蝕性能遠優(yōu)于鈦合金；抗氧化性能優(yōu)于Ti。

    Abstract:

    Both CrN hard coatings and CuNiIn solid lubricating films were produced on the titanium alloy substrate by the ion beam enhanced deposition (IBED) technique. The electrochemical corrosion behavior and galvanic corrosion sensitivity of the IBED films and titanium alloy in NaCl solution were studied by using electrochemical measurement methods. The oxidation resistance of the IBED films was evaluated by the elevated temperature static oxidation method. The results show that both the electrochemical corrosion resistance and the oxidation resistance of IBEDD CuNiIn film are better than those of bulk copper. IBED CuNiIn film is contact compatible with titanium alloy substrate in Cl- solution. IBED CrN film has good corrosion resistance compared with the titanium alloy in both Cl- solution and HCl + HF mixed acid solution, it can directly contact with titanium alloy in Cl- solution. The oxidation resistance of CrN film is better than that of the titanium alloy substrate.
