TARGET DESIGNED TO BE VAPORIZED BY AN ELECTRON BEAM, THE PROCESS FOR MANUFACTURING THE SAID TARGET, THERMAL BARRIER AND COATING OBTAINEDFROM THE USE OF SUCH A TARGET, AND MECHANICAL PARTS ON WHICH SUCH A COATINGIS USED

摘要

The invention relates to a bar-shaped composite target formed of ceramic powders and intended for electron beam evaporating, comprising zirconia and at least one stabilizer for zirconia. Typically, said target is characterized in that said zirconia stabilizer is included with a molar content of between 2 and 30% and in that said zirconia is formed more than 90% of a monoclinic phase. Application to the manufacture of a thermal barrier of low thermal conductivity and high thermomechanical resistance in ceramic formed by evaporation under electron beam.
