Abstract

The results of studies of the zeta potential, pH, and electrophoretic deposition (EPD) characteristics of Ce_0.8Sm_0.2O_1.9 (SDC-m) micropowder suspensions with SDC-n nanoparticles added in different proportions are presented. It is shown that a suspension of microsized particles is stabilized due to the introduction of highly charged nanoparticles. The thickness of the coating changes nonmonotonically during the EPD from an SDC-m/SDC-n suspension at higher contents of SDC-n nanoparticles, while the zeta potential and resistance of the suspension tend to increase. It is shown that the greatest thickness of a continuous and homogeneous SDC coating is achieved at a 5 wt % content of SDC-n nanoparticles.

纳米颗粒稳定掺杂二氧化铈微颗粒悬浮液的电泳性能

研究了添加不同比例的SDC-n纳米粒子后Ce0.8Sm0.2O1.9 （SDC-m）微粉悬浮液的zeta电位、pH和电泳沉积（EPD）特性。结果表明，由于高电荷纳米粒子的引入，微颗粒悬浮液是稳定的。在SDC-m/SDC-n悬浮液的EPD过程中，随着SDC-n纳米粒子含量的增加，涂层厚度呈非单调变化，而zeta电位和电阻呈增加趋势。结果表明，当SDC-n纳米粒子的含量为5 wt %时，SDC涂层的连续均匀厚度达到最大。
