Microstructure Analysis of FeS Layer as Solid Lubrication Composite Coating Produced by Low-Temperature Ion Sulfurization
The ferrous sulfide (FeS) solid lubrication composite layer was prepared on the surface of CrMoCu alloy cast iron that treated by ion Nitrocarburizing, with low-temperature ion sulfurizing technique. By morphology and composition analysis, it is shown that the FeS layer has a micro-nano-hole structure, formed by nanometer sulfide particles, and the composite layer surface is mainly FeS. Also, there are a cross area and a diffusion area between the ion sulfide layer and the ion nitrocarburizing layer.
