    摘要:

    為了提高鈦雙極板的耐蝕性能，采用磁控反應濺射技術和脈沖沉積技術在商業(yè)純鈦TA1表面制備了氮化鈦（TiN）薄膜，并對不同工藝參數(shù)下制備的薄膜進行了評價。結果表明，在不同制備工藝下TA1表面均可以形成致密完整的TiN膜，并顯著提高鈦基體的腐蝕電流密度。其中，磁控反應濺射所制備的薄膜成分受到氧氣競爭反應的影響，其均一性低于脈沖激光沉積所制備的薄膜，脈沖激光沉積制備的薄膜在低腐蝕電流密度（0.025 μA·cm-2）、中等腐蝕過電位（–0.106 V）和良好的疏水性方面具有更優(yōu)異的綜合性能。

    Abstract:

    To improve the corrosion resistance of titanium (Ti) bipolar plate, titanium nitride (TiN) film was prepared on the surface of commercial TA1 pure titanium by magnetron reactive sputtering and pulse laser deposition (PLD) techniques, and the film prepared under different process parameters were evaluated. Results show that dense and complete TiN film can be obtained on TA1 surface under different preparation processes, and the corrosion current density of Ti substrate significantly increases. However, the composition of the film prepared by magnetron reactive sputtering is affected by the oxygen competition reaction, and its homogeneity is inferior to that of the film prepared by PLD. The comprehensive performance of the PLD-prepared film shows excellent characteristics in the terms of low corrosion current density (0.025 μA·cm-2), moderate corrosion overpotential (-0.106 V), and good hydrophobicity.
