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.

用于显示面板玻璃制造的浮法中暴露于高温环境的进料辊的氧化钇稳定的氧化锆（YSZ）陶瓷涂层具有高硬度，低孔隙率并且在高温环境下不会开裂。为了获得玻璃面板制造所必需的这些性能，进行了各种参数的分析，例如粉末粒度，等离子喷嘴直径，粉末进料速率和涂覆距离。结果表明，硬度约为800–1019 Hv 0.1，比一般的YSZ涂膜高150％。可以得到孔隙率为1.4〜3.0％的致密的涂膜，该孔隙率比一般的孔隙率低50％。还发现在850°C的热冲击后没有出现裂纹的情况。
