%X The friction and wear behaviors of two types of C/C composites with different structures sliding against W18Cr4V steel at elevated temperatures were investigated on an MG-2000 tester in a pin-on-disc configuration, using high-strength graphite which was supposed to be used to prepare the seal-ring of the main axis of an aviation engine as a control. The composition and morphology of the worn composite surface was analyzed by means of Raman spectroscopy and scanning electron microscopy. It was found that the C/C composite with a rough lamination and smooth lamination complex structure showed much better wear-resistance than the high-strength graphite at elevated temperature, thus it could be used as a promising candidate material to prepare the seal ring of the main axis of the aviation engine. The C/C composites were dominated by abrasive wear, adhesion wear, and oxidation wear, in the dry sliding against the steel at elevated temperatures.
