The microstructures of a Mo–Si–C–N coating, synthesized in a flowing nitrogen atmosphere by fused slurry, have been characterized in detail by means of X-ray diffractometry, scanning electron microscopy (SEM) and transmission electron microscopy (TEM). The results indicate that the Mo–Si–C–N coating has a four layer structure consisting of a SiC bonding layer, MoSi2/Si main layer, sialon–ceramic subsurface layer and SiC nanowire surface layer. The SiC bonding layer formed by the diffusion of Si and C atoms is very dense and consists of β-SiC nano-grains. No crack or defect is found on the two-sided interface of the SiC bonding layer, indicating that the SiC bonding layer has strong bonding with the C/C composite substrate and MoSi2/Si main layer. The MoSi2/Si main layer is covered with a sialon–ceramic subsurface layer of about 5 m in thickness. The sialon–ceramic subsurface layer plays an important role in further improving the oxidation resistance of the Mo–Si–C–N coating due to its excellent anti-oxidation properties. β-SiC nanowires with a substructure of twin and stacking faults growing along the 111 direction constitute the surface layer of the Mo–Si–C–N coating with a thickness of about 10 μm. To minimize the surface energy as well as total free energy, the SiC nanowires have surfaces with a fixed faceted angle, which accords with the intersection angle of the adjacent (111) close-packed plane in the faced-centred cubic structure.
