    摘要: In the plasma spraying according to the present embodiment, the zircon powders are excessively heated to raise the average temperature of the molten particles to a temperature range of 2820 to 4200°C. As a result, SiO2 in the zircon powders is vaporized, and the component ratio of ZrO2 in the molten particles is relatively increased. Such zircon powders land on the surface of the base material, and the deposit coagulates, the coagulum forms a thermal sprayed coating with a high composition ratio Zr/Si.
