The invention relates to the technical field of coating preparation, and particularly discloses a coating as well as a preparation method, a product and application thereof. The coating is prepared by adopting chemical vapor deposition, and the chemical vapor deposition conditions are as follows: the heating temperature is 1095-1105 DEG C, the pressure is 1500-2500Pa, the composite gas is a carbon source precursor and nitrogen, and the residence time of the composite gas is 7-12s. The loss W% of the coating at 2000 DEG C for 100 h is smaller than or equal to 3.81%, the mass ablation rate Rm of the coating at 3000 DEG C for 20 s is smaller than or equal to 5.0 mg/s, the oxidation resistance and ablation resistance of a matrix can be improved, and the problems of crusting and carbon black are avoided. The coating prepared by the invention is mainly applied to a photovoltaic thermal field component and a thermal shielding component, so that the oxidation resistance and ablation resistance of the photovoltaic thermal field component and the thermal shielding component are improved, and the service life of the photovoltaic thermal field component and the thermal shielding component is further prolonged.
