Abstract
The yttria stabilized zirconia (YSZ) ceramic coating of feed rollers exposed to the high temperature environment used in the floating process for display panel glass manufacturing has high hardness, low porosity and no cracking in the high temperature environment. To obtain such properties, which are necessary for glass panel manufacture, analysis of various parameters such as powder particle size, plasma nozzle diameter, powder feeding rate, and coating distance, was carried out. The results demonstrated a hardness of about 800–1019 Hv 0.1, 150 % higher than the general YSZ coating film. It was possible to obtain a dense coated film with a porosity of 1.4 to 3.0 %, which is 50 % lower than the general porosity. The condition where no cracks occur after an 850 °C thermal shock was also found.
