采用双阴极放电技术，采用纯Al掺杂不同比例α-Al2O3的混合靶材，在316L不锈钢（SS）表面制备了含有α-Al2O3晶种的Al层。然后，在580°C下进行等离子体氧化后获得Al2O3涂层。采用掠射角(1°)X射线衍射仪(GAXRD)和扫描电子显微镜(SEM)分别研究了涂层的物相组成、微观结构和形貌。此外，还测量了涂层的结合力和耐腐蚀性。结果表明，α-Al2O3 以 Volmer-Weber 模式在籽晶周围成核和生长。 Al2O3涂层致密、耐蚀性和冶金结合良好。讨论了不同组分α-Al2O3的诱导作用。当使用含有 10% α-Al2O3 的靶材时，α-Al2O3 (5.5 wt.%) 分布在 Al 层中。等离子体氧化后，得到了65.54 wt.%的α-Al2O3，比相同条件下纯Al氧化得到的α-Al2O3提高了10.34%。然而，随着α-Al2O3晶种含量的进一步增加，诱导效果变弱。
Al layer with α-Al2O3seed crystals was prepared on the surface of 316L stainless steel (SS) by a double cathodes discharge technique, in which the mixed targets of pure Al doped with different proportions of α-Al2O3were used. Then, Al2O3coatings were obtained after plasma oxidization at 580 °C. The phase composition, microstructure and morphology of the coatings were studied respectively by means of glancing-angle (1°) X-ray diffractometry (GAXRD) and scanning electron microscopy (SEM). Furthermore, the bonding force and corrosion resistance of the coatings were measured. The results indicated that α-Al2O3nucleated and grew surrounding the seed crystals as the Volmer–Weber Mode. The Al2O3coating was compact, performing a good corrosion resistance and metallurgical bonding. The inducing effects of α-Al2O3with different fractions were discussed. α-Al2O3(5.5 wt.%) was distributed in the Al layer when the target possessing 10% α-Al2O3was used. After plasma oxidation, 65.54 wt.% α-Al2O3was obtained which was 10.34% more than that obtained by the oxidation of pure Al at the same condition. However, the inducing effects became weak with the further increment of content of α-Al2O3seed crystals.
