请使用高级语法及词汇润色以下句子：Besides the number of Cr atoms decomposed from Cr2AlC increases with the sintering temperature which reacts with the carbon atom on the graphite surface to form the Cr3C2 interfacial

Moreover, the quantity of chromium atoms liberated from the Cr2AlC compound augments in tandem with the rise in sintering temperature. These atoms subsequently interact with the carbon atoms present on the graphite surface, instigating the formation of an interfacial layer consisting of chromium carbide (Cr3C2), which in turn facilitates the bonding of copper and graphite. Additionally, it is noteworthy that the hardness of the composites escalates in proportion to the sintering temperature, while the conductivity of the composites remains relatively constant despite the increase in sintering temperature.
