Experimental results confirmed a higher onset oxidation temperature of HZSC powders (640 °C) than HZMC powders (440 °C), and HZSC coating demonstrated superior ablation resistance (240 s) relative to HZMC coating (180 s). First-principle calculations by VASP displayed a higher O storage capacity in the HZSC lattice due to a lower average O-interstice energy of HZSC (-2.10 eV) than HZMC (44.52 eV). It avoided the rapid consumption of C atoms and subsequent HZSC lattice collapse during initial oxidation/ablation, followed by slowing down the average high-temperature O atom migration of HZSC (2.58 Å-6.83 Å, from 25 °C to 2180 °C) in comparison to HZMC (3.09 Å-7.66 Å).
