Abstract

Partially yttria-stabilized zirconia (YSZ) films were prepared by laser chemical vapor deposition (LCVD). The assistance of laser increased the deposition rate for YSZ films up to 660 μm/h. The increase in the deposition rate was accompanied by plasma formation around the deposition zone, and the plasma was observed over critical laser power and substrate pre-heating temperature. A wide variety of morphologies of films from feather-like columnar to dense textures were obtained depending on deposition conditions. The columnar texture contained a large amount of nano-pores at columnar boundary and inside grains. These columnar texture and nano-pores were advantageous for applying YSZ films to thermal barrier coatings.
