Abstract (en)

[origin: WO2016097112A2] Part made of a ceramic comprising at least one metalized outer surface, comprising a compositionally graded coating, said coating successively comprising from the outer surface toward the ceramic in the direction of the thickness of the coating: a surface layer formed by a metal M; a layer of an oxide of the metal M: MkOw where k ranges from 1 to 3 and w ranges from 1 to 4; a layer of a reaction compound between the oxide of a metal M and the ceramic which has a composition gradient, which is preferably continuous, in the direction of the thickness of said layer, with a content of metal M that decreases, preferably continuously, toward the ceramic. Process for preparing this part. Process for assembling a first part made of a ceramic with a second part made of a metal or made of a ceramic in which at least one surface of a first part made of a ceramic is metalized by said process.
