Title:
SURFACE TREATMENT METHOD FOR THERMAL-SPRAY CERAMIC COATING FILM, AND THERMAL-SPRAY CERAMIC COATING FILM
Document Type and Number:
WIPO Patent Application WO/2023/190838
Kind Code:
A1
Abstract:
Provided are: a surface treatment method for smoothing the surface of a thermal-spray ceramic coating film; and a thermal-spray ceramic coating film which has undergone the surface smoothing treatment. The surface treatment method for a thermal-spray ceramic coating film is characterized in that a slurry which comprises a liquid having a viscosity of 10 mPa/s or less at a temperature of 20°C and a powdery medium having a polyhedral shape and having a median diameter (D50) of 1-50 μm and which has a content of the powdery medium of 1-50 vol% is jetted against the surface of the thermal-spray ceramic coating film at a pressure of 0.01-1.0 MPa using a compressed gas, thereby smoothing the surface of the thermal-spray ceramic coating film.
