Title:
CERAMIC COATING FORMATION USING TEMPERATURE CONTROLLED GAS FLOW TO SMOOTH SURFACE
Document Type and Number:
Japanese Patent JP2021110036
Kind Code:
A
Abstract:
To provide a method and a coating system (100) that use a temperature controlled gas flow (142) to smooth a surface (114, 166, 170) of thermal barrier coating (TBC) (112).SOLUTION: Thermal spray coating unit (110) coats a TBC (112) on a surface (114, 166, 170). The thermal spray coating unit (110) creates a flow of TBC material (124) towards the surface (114, 166, 170). A surface (114, 166, 170) of uncured TBC material (144) on the surface (114, 166, 170) is smoothed by transmitting a flow of temperature controlled gas (142) across the uncured TBC material (144) on the surface (114, 166, 170) after the thermal spray coating of the TBC (112) on the surface (114, 166, 170). The cured TBC (112) has a smoother surface (114, 166, 170) that requires much less polishing to attain a desired surface roughness.SELECTED DRAWING: Figure 1
