工业板材零件制造对使用高性能材料的需求不断增长，促使我们制造波形板材纳米复合材料。采用浸渍法和等离子喷涂成型（PSF）相结合的方法来制造Al/多壁碳纳米管（MWCNT）片纳米复合材料。通过在纯铝基体中添加 5 wt.% MWCNT，显微硬度增加至 34.5 (VHN)，而单片纯铝的显微硬度为 30 (VHN)。还研究了使用涂层 MWCNT 作为增强材料的效果。我们的结果表明，应用涂层 MWCNT 不仅可以显着提高显微硬度（50 VHN），而且可以减少 MWCNT 侧壁上产生的缺陷。
The growing demand for using high-performance materials for industrial sheet parts manufacturing actuated us to fabricate wave-formed sheets nanocomposite. A combination of impregnation method and plasma spray forming (PSF) was used for manufacturing of Al/multiwall carbon nanotube (MWCNT) sheets nanocomposite. By addition of 5 wt.% MWCNT to pure Al matrix, microhardness increased to 34.5 (VHN) compared to 30 (VHN) for monolithic pure Al. The effect of using coated MWCNT as a reinforcement material was also investigated. Our results showed that applying coated MWCNT not only lead to significant increase of microhardness (50 VHN), but also less defect was generated on the MWCNT sidewalls.
