- 摘要:
- 为了探讨 Mo 或 W 元素掺杂对 Co-P 合金薄膜结构和性能的影响机理，采用化学镀法分别制备 Co-Mo-P 和 Co-W-P 合金薄膜，研究其结构、物相组成、微观形貌、磁性能和耐腐蚀性能，并与 Co-P 合金薄膜进行比较。结果表明： Co-Mo-P 合金薄膜和 Co-W-P 合金薄膜都呈晶态结构，除单质 Co 相以外，还形成置换固溶体 Co 3 Mo 相、 Co 3 W 相。与 Co-P 合金薄膜相比， Co-Mo-P 合金薄膜和 Co-W-P 合金薄膜的磁性能较好，耐腐蚀性能提高。 W 原子进入 Co 晶格中形成置换固溶体 Co 3 W ，起到较好地促进结晶细化效果，使 Co-W-P 合金薄膜表面结构更紧凑致密，具有更强地阻碍畴壁移动和阻挡腐蚀介质侵蚀的能力，因此其磁性能和耐腐蚀性能更好。
- Abstract:
- ： Co-Mo-P alloy films and Co-W-P alloy films were prepared by electroless plating in order to investigate the effect mechanism of Mo or W elements doping on the structure and properties of Co-P alloy films. The structure ， phase composition ， microstructure ， magnetic property and corrosion resistance of Co-Mo-P and Co-W-P alloy films were investigated and compared with those of Co-P alloy films. The results showed that both Co-Mo-P alloy films and Co-W-P alloy films had crystalline structure ， and the phase composition included not only Co phase ， but also substitution solid solution Co 3 Mo phase or Co 3 W phase. Compared with Co-P alloy films ， Co-Mo-P alloy films and Co-W-P alloy films had better magnetic property and corrosion resistance. The substitution solid solution Co 3 W was formed because W atoms entered into the Co lattice ， which can better promote the crystallization refining ， make the surface structure of Co-W-P alloy film more compact and compact ， and improve the ability of block the movement of domain walls and resist the erosion of corrosive media. Therefore ， Co-W-P alloy films showed excellent magnetic properties and corrosion resistance.
