Abstract:
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.

Claim (Index 1):
A method for forming a thermal sprayed coating comprising a step of supplying thermal spraying powders to flame from a thermal spraying gun to spray and deposit on a constitution surface of a combustion chamber of an engine, wherein:\n the thermal spraying powders are ceramics powders composed of ZrO2-SiO2 based ceramics; in the step for supplying the thermal spraying powders, average temperature of the supplied ceramics powders is increased within a temperature range being higher than vaporization temperature of SiO2 which constitutes the ceramics powders and lower than vaporization temperature of ZrO2 which constitutes the ceramics powders; and a composition ratio Zr/Si of the deposit on the constitution surface is 1.5 or more.
