调制结构对c-VC/h-TiB2纳米多层膜的超硬效应的影响
Influence of modulation structure on the superhardness effect in c-VC/h-TiB2 nanomultilayer
摘要
Abstract
In order to reveal the relationship between modulation structure and superhardness effect, a series of c-VC/h-TiB2 nanomulti-layers with different modulation structures is synthesized by magnetron sputtering technique. X-ray diffractometer, high-resolution transmission electron microscope and nanoindention device are employed to investigate the microstructures and mechanical properties of the multilayers. Based on the experimental results, a relation map of modulation structure and superhardness effect is established for the nanomultilayer composed of c-VC and h-TiB2 with four regions. In these regions, superhardness effect could be generated only in the region with sharp interface and coherent growth structure. In other regions, the change of modulation structure leads to the change of the microstructure, and the hardness will decrease accordingly. The map could provide reference for obtaining superhardness effect by designing modulation structure in those analogous heterogenous nanomultilayers.关键词
