Abstract

Rare-earth oxides are known to stabilize the cubic and tetragonal phases of zirconia. This paper presents the preparation of samaria-stabilized zirconia powders and coatings by plasma spraying. The amount of samaria ranged from 2 to 10 mol%. The tetragonal phase is stabilized when 2 to 6 mol% samaria are added. There are evidences that suggest the formation of enforced solid solution of the tetragonal phase in the composition range 4-6 mol% Sm₂O₃. Transformation to the cubic phase occurred after heat treatment at 1400°C for 10 h.
