In order to address the issues of wettability and scattering between matrix and reinforcement and enhance corrosion resistance, the effects of incorporating hexagonal boron nitride (h-BN) into magnesium-carbon nanotubes (Mg-0.5 wt% CNTs) nanocomposites were successfully investigated. An inventive coating with h-BN using a novel electroless chemical deposition technique and double stir casting were used. The composites were produced by varying weight percentages of h-BN (0, 2, 4, and 6). The corrosion testing, microstructural analysis, and physical testing of the samples were carried out. A corrosion resistance of 75.1% was obtained when the 4 weight percent of h-BN content was compared to Mg-0.5% wt% CNTs. Even though the relative density increased noticeably, this was due to the uniform dispersion of h-BN nanoparticles over the entire surface. Researchers have established that adding 4 wt% h-BN to the Mg-0.5 wt% CNT nanocomposite can improve the wettability between Mg and CNTs and enhance the corrosion resistance properties.
为了解决基体与增强体之间的润湿性和散射问题，并提高耐腐蚀性，成功研究了将六方氮化硼（h-BN）加入镁-碳纳米管（Mg-0.5 wt% CNTs）纳米复合材料中的效果。使用了一种新颖的化学沉积技术和双搅拌铸造法制备含h-BN的创新涂层。通过改变h-BN的重量百分比（0、2、4和6）来制备复合材料。对样品进行了腐蚀测试、微观结构分析和物理测试。当将4重量百分比的h-BN含量与Mg-0.5% wt% CNTs进行比较时，获得了75.1%的耐腐蚀性。尽管相对密度显著增加，但这是由于h-BN纳米颗粒在整个表面上的均匀分散所致。研究人员已确定，在Mg-0.5 wt% CNT纳米复合材料中添加4 wt% h-BN可以改善Mg与CNTs之间的润湿性，并增强耐腐蚀性能。
