| 摘 要： | 采用加弧辉光离子渗金属新技术处理钛合金Ti5Al2.5Sn表面，研究了渗层的相组成特点，成分分布情况，评价了改性层的磨擦摩损性能，及与钛合金基体间的接触腐蚀相容性等。结果表明加弧辉光离子渗技术可以快速地在钛合金表面获得NiCr镀渗复合层。渗层由Ni3Ti等金属间化合物组成，其硬度、耐磨性能均高于离子注氮层，具有较高的抗含Cl^-1水溶液腐蚀性能，在含Cl^-1腐蚀环境中与钛合金基体接触相容。 |

| Abstract: | A new technique of glow discharge ionized surface alloying with arc source was used to treat Ti5Al2 5Sn alloy The microstructure and constituent distribution in diffusion layer were studied The wear resistance and the galvanic corrosion susceptibility of the alloyed surface layer contacted with titanium alloy Ti5Al2 5Sn were evaluated It is found that a composite modified surface of NiCr coating over nickel chromium diffusion layer can be quickly formed with the new technology The alloyed surface consists of Ni 3Ti, Ni 3Al, Cr 2Ti and other phases The hardness and the wear resistance of the alloyed surface are higher than that of nitrided surface The modified titanium alloy has high corrosion resistance in Cl 1 environment and low galvanic corrosion susceptibility contacted with Ti base metal |
