Plasma-sprayed coatings of yttria-stabilized ZrO2 and Al2O3. TiO2 used as a protective barrier on β-Si3N4-based sialon ceramics were investigated. The coatings showed better cohesion with the pre-oxidized surfaces due to the reaction between the SiO

A "double-torsion" test jig for operation in vacuum or a selected gas atmosphere at temperatures up to 1500°C is described. The jig has been used to determine stress intensity (K I )-crack velocity (v) relationships for single-phase β' Si-Al-O-N ce
