Abstract
The invention relates to the thermal barriers, to a process and material for their production, and to their application. Thermal barriers consist of a material comprising at least one refractory oxide with low thermal diffusivity and at least one quasicrystalline aluminum alloy, the proportion of which represents from 2-30% by volume. They can be produced by deposition of a mixture of refractory oxide and of quasicrystalline alloy in vapor phase, or from a mixture of refractory oxide and quasicrystalline aluminum alloy in the molten state, or else by deposition onto the support to be protected with the aid of an oxygen-gas torch fed with material using a flexible cord which contains the refractory oxide and the quasicrystalline alloy. The applications include the protection of components of aircraft or motor vehicle engines, of aeronautical or aerospace components, of chemical reactors or of electrical households appliances.
