In this study, nanosized B₄C and graphite-reinforced ZA27 matrix hybrid nanocomposites were produced with mechanical milling followed by hot pressing. The friction coefficient values of nanocomposite samples remarkably decreased from 0.5036 (± 0.085) to 0.2575 (± 0.021) with the increase of milling time to 24 hours for nanocomposite powders. That was almost two times lower than those of unmilled nanocomposites. It was determined that the good distribution of reinforcement particles in the microstructure and low grain size allowed the formation of a protective oxide layer against corrosion. The corrosion resistance of the nanocomposite materials obtained from nanocomposite powders milled for 24 hours was quite superior to the others. The results revealed that the corrosion rate values were 29.068 and 4.033 mpy for hybrid nanocomposite samples produced from unmilled and milled powders for 24 hours, respectively.

在这项研究中，纳米B ₄C和石墨增强的ZA27基质杂化纳米复合材料是通过机械研磨然后热压生产的。随着研磨时间的增加，纳米复合材料粉末的纳米复合材料样品的摩擦系数值从0.5036（±0.085）显着降低至0.2575（±0.021）。这几乎是未研磨的纳米复合材料的两倍。可以确定的是，增强颗粒在微观结构中的良好分布和较低的晶粒尺寸允许形成抗腐蚀的保护性氧化物层。由研磨24小时的纳米复合粉末获得的纳米复合材料的耐腐蚀性优于其他材料。结果显示腐蚀速率值为29.068和4。
