Ceramic coating spraying method and device and computer readable medium

The invention provides a ceramic coating spraying method and device and a computer readable medium which are used for spraying a ceramic coating with gradient changing thickness on the surface of a component. The ceramic coating spraying method comprises the following steps: determining a coating area, needing to be sprayed with the ceramic coating, on the component; determining the size of a spot formed when a spray gun sprays on the component; according to the size and shape of the coating area, the thickness distribution of the required ceramic coating and the size of the spots, determining at least two spraying tracks of the spraying gun; and grouping the spraying tracks according to the thickness distribution of the needed ceramic coating on the coating area, obtaining at least two spraying track sets, wherein each spraying track set comprises at least one spraying track, and when the spraying gun moves and sprays on the spraying area layer by layer along the spraying tracks in the spraying track sets, f
