, 2017 采用线性离子束技术在PET基材表面制备类金刚石薄膜,分析薄膜结构、性能随离子束电流的演变规律并研究了薄膜润湿特性与表面形貌、结构、表面能的作用关系。结果表明:沉积在PET表面的类金刚石薄膜具有典型的非晶碳膜结构特征,随着离子束电流的增大sp~2/sp~3比值由0.774增加到1.622,薄膜表面的石墨化程度提高;改性后的PET材料接触角从63.51°增大到103.7°。进一步分析发现,疏水性能的提高归因于材料表面能的降低,表面石墨化程度的提高和微-纳结构的形成是表面能降低的根本原因。此外 ...

氮分压对钕铁硼表面直流磁控溅射沉积AlN/Al防护涂层结构和性能的影响
, 2010 采用直流磁控溅射在钕铁硼表面沉积AlN/Al 双层防护薄膜来提高磁体的耐腐蚀性能。先在基体表面沉积纯 Al 薄膜，然后沉积外层AlN 薄膜。沉积AlN 薄膜时，改变氮气分压，研究氮分压对薄膜结构和耐腐蚀性能的影响。 结果显示，AlN 纳米颗粒形成于内层Al 结晶体表面。氮氩分压比为1:1 时，钕铁硼表面形成了更致密的AlN/Al 薄膜。 膜基界面存在元素的互扩散和冶金结合。氮氩分压为1:1 的AlN/Al ...
