| Abstract: | A series of nanoscale ReB2/ TaN multilayered coatings were prepared by ultra-high vacuum RF magnetron sputtering system at 20℃.The influence of modulation period(Λ) on the microstructure and mechanical properties of the film was investigated by SEM,XRD,surface profiler and nano-indenter.The results showed that ReB2 and TaN layers exhibited hexagonal structure in films.ReB2/TaN multilayers have superhard effects with a modulation period from 8-12nm.At Λ=9.6nm,ReB2/TaN multilayered possessed the highest hardness of 28.8GPa and modulus of 345.9GPa with lower residual stress. |
