Figure 2 presents the X-ray diffraction patterns of the composites, which were manufactured through Spark Plasma Sintering (SPS) utilizing Cu, Cu-coated graphite, and Cr2AlC raw materials at different temperatures. Upon scrutinizing the data, it becomes evident that a faint Cr2AlC diffraction peak is detectable in the X-ray diffraction pattern of the composites when the sintering temperature reaches 800 °C.
