摘要： The invention relates to a ceramic thermal barrier composition of low conductivity and high high-temperature strength. In characteristic manner, the composition comprises a zirconia base, at least one trivalent oxide enabling the zirconia to be stabilized and enabling the thermal conductivity of the zirconia to be reduced in optimum manner, and at least one pentavalent oxide enabling the content of oxygen vacancies to be reduced so as to make it substantially equal to that of a partially stabilized zirconia. Preferably, said trivalent oxide is present with a molar content constituted by a first portion enabling the zirconia to be stabilized partially and a second portion which introduces point defects into the lattice said pentavalent oxide is present with a molar concentration equal to said molar concentration of said second portion of the trivalent oxide. The invention is applicable to making a superalloy machine part having a ceramic coating with said composition, and possibly also a bonding underlayer.

摘要： An insulating material is fed in and shaped by superposing a plurality of N layers Ci (3) of the insulating material. For each layer Ci, a plurality of ni, axial insulating elements Ei precut from the insulating material is formed, a rough form of the tubular insulating device is formed by using an adhesive to assemble the Ni elements Ei of each layer Ci which are juxtaposed along a plurality of joining zones Ji, so that the plurality of joining zones Ji+1 of a layer Ci+1 is offset relative to the plurality of joining zones Ji, of the adjacent layer Ci. Then, by the adhesive is polymerized, and the tubular element rough form is subjected to a heat treatment. The method is economical and makes it possible to obtain a device of high mechanical strength.
