采用AlBi2+2%AlB10电弧靶与Ti靶中频磁控溅射共沉积的工艺,在高速钢基体上形成Ti-Al-B-N多元复合涂层.电子扫描电镜(SEM)、X射线衍射(XRD)分析结果表明:涂层由TiN的柱状结构转变为TiAlBN的多层混合结构,组织更为致密均匀;通过调节电弧电流,增加Al、B元素剂量,涂层晶面取向生长增多,并逐渐出现新相.涂层的显微硬度和耐磨性测试表明,随膜层中Al、B成分的增加,膜层维氏硬度增大,耐磨性能提高.
Ti-Al-B-N compound coatings were deposited on polished surface of high speed steel by arc ion plating together with intermediate frequency unbalanced magnetron sputtering.The analysis results of SEM and XRD indicate that the size of droplets on the surface of TiAlBN is smaller than that on the TiN films,the defects are eliminated on a large scale,and the microstructurc of the sulfate is more compact and uniform.The lattice distortion of TiN films is caused by the addition of AI,B element,and the new phase appeares.Its surface hardness and wear resistance are also improved obviously.
