The present invention relates to a slurry composition for suspension plasma thermal spray, a preparation method therefor, and a suspension plasma thermal spray coating film. More particularly, the present invention relates to a slurry composition for suspension plasma thermal spray, which can be stably applied in a corrosive environment because the composition of an oxygen component and a fluorine component contained in a thermal spray coating film does not change when the thermal spray coating film is manufactured, can be applied in various corrosion-resistant environments because various crystal structures can be formed and controlled, and at the same time, can form a denser thermal spray coating film than the conventional thermal spray coating film by suppressing the formation of cracks and pores that have occurred in the conventional thermal spray coating film; a preparation method therefor; and a suspension plasma thermal spray coating film.
