After the W coating is heat treated at 1500 °C for 1 h, W2C and dense WC layers are formed at the surface and interface, respectively. During ablation, the WC covered with pyrolytic carbon overcomes its brittleness and shows better ablation resistance by forming a chemical bond with pyrolytic carbon to prevent the penetration of oxygen. To improve the ablation resistance of C/C composites, tungsten (W) coating is applied by chemical vapor deposition (CVD) technology on C/C composites. Results show that the coatings are dense, with a thicknes...
