Although aluminum and its composites have been used in many applications, their mechanical properties should be improved for use in wider applications. Hence, specially nanosized and sub-micron sized carbonaceous additives were used. As far as is known, hydrothermal carbons (HTCs) have not yet been used in aluminum-silicon matrix composites. In this study, two different morphologies of HTCs were synthesized from cellulose and chitosan. With the use of chitosan, the particle morphology of HTCs was changed from hard spheres to smaller aggregated spheres. Both HTCs had a positive effect on mechanical (hardness>%18, and ultimate compression strength>%9) and tribological properties (wear rate>% 14) and they caused only limited decrement of corrosion resistance (corrosion rate<%13). The aggregated spheres possessed HTCs presented better mechanical, tribological and corrosive properties than those the hard spheres possessed.

虽然铝及其复合材料已被用于许多应用，但它们的机械性能应得到改进以用于更广泛的应用。因此，使用了特殊的纳米尺寸和亚微米尺寸的碳质添加剂。据了解，水热碳（HTC）尚未用于铝硅基复合材料。在这项研究中，从纤维素和壳聚糖合成了两种不同形态的 HTC。随着壳聚糖的使用，HTCs 的颗粒形态从硬球变为较小的聚集球。两种 HTC 对机械（硬度>%18，极限压缩强度>%9）和摩擦学性能（磨损率>%14）都有积极影响，并且它们仅导致有限的耐腐蚀性下降（腐蚀率<%13）。
