摘要

A basic research study for improvement of plasma-sprayed zirconia coatings has been conducted. Wettability of porous ZrO_2-Y_2O_3MnO substrates by manganese has been investigated at 1573K by the sessile drop method. The contact angles tend to decrease gradually and stabilized at 85-90 degrees. Those values are larger than that for dense substrate. Thus the pores have a great influence on kinetics of wetting.
