The coating bead flow and operability window for Newtonian coating liquids are theoretically and experimentally investigated in the slot coating process, with a focus on the shape of the upstream ...

Coating equipment with a 5 cm wide dual-slot die for directly visualization of the slot coating flows is displayed schematically in Fig. 2. The lengths of the upstream and downstream die lips are both 1000 μm, and the mid block is 500 μm in length, as used in the viscocapillary and 2-D models. Operability coating windows and frequency response in slot coating ...

Highlights Homogenous lithium-ion battery electrodes were slot-die coated at high velocities. Coating defects were found which match but could not be explained by the low-flow limit. The film-roughness increases when the dimensionless gap width increases. A range of coating parameters was found, that defines a “quality window”.

However, the ceramic coating materials showed separations in the coating interface between the substrate and coating layer, or between the coating layer and fuel melt after the dipping test. blade root offset: Topics by WorldWideScience.org In this paper, a finite element model has been created for the purpose of assessing stress at the joint region connecting the blade to the disc slot.
