摘要:
利用可移动活性屏低温离子渗流技术（简称ASPS技术），考察了工艺参数对渗硫层形貌、结构等的影响，制备了具有微纳结构的FeS固体润滑渗硫层。研究发现，渗硫温度比保温时间对FeS固体润滑渗硫层的形貌和组成结构影响更大。当渗硫温度230 ℃、保温2 h时，渗硫层以FeS为主，但含少量的FeS2，渗硫层中S/Fe原子摩尔百分比值接近1。渗硫层由微纳米量级的硫化物颗粒堆积而成，表层为富S层、次表层为FeS层，在渗硫层和基体之间存在厚度约400 nm的扩散层。

Abstract:
By utilization of active screen plasma sulphurizing technology (ASPS technology), the FeS solid lubrication layer with micro/nano structure was prepared. The influence of processing parameters on the morphologies and structures of the sulphide layer was examined, and the results showed that the sulphurizing temperature affects the morphologies and structures of FeS solid lubrication layer greater than the treat time. The atom mol percent ratio of S to Fe was close to 1.0 when the optimizing technics parameters was 230 ℃/2 h, and it was mainly composed of FeS. The active screen ion sulphurizing layer was piled by micro/nano sulfide particles, which can be divided into three layers: top surface S–rich layer，Sub–surface FeS layer and a sulphide diffusing layer of about 400 nm adjacent to substrate.
