摘要:
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: M k O w 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.

Dispositif pour le refroidissement d'air à destination d'un échangeur thermique, en particulier pour une installation de conversion de chaleur en électricité, le dispositif comprenant une structure (30) dotée d'un matériau sensible (34) et configurée de sorte à pouvoir être mise en communication avec l'extérieur pour pouvoir permettre en circulation de l'air ambiant au travers le matériau sensible et réaliser un échange thermique avec le matériau sensible, la structure (30) comprenant en outre un matériau adsorbant (38) d'humidité, pour piéger l'humidité de l'air extérieur mis en circulation et traversant la structure (30), le matériau adsorbant (38) étant un matériau adapté pour désorber l'eau à une température inférieure à 50°C, pour une humidité relative inférieure à 50%.
摘要:
The invention relates to an annular sintered magnet with a radially oriented remanent magnetic field, comprising: an annular main part made of a ferromagnetic material wherein a first degree D1 of magnetic anisotropy is provided in the radial direction of the magnet; and an annular reinforcing part which is secured to the main part of the magnet and made of the same ferromagnetic material as the main part, wherein a second degree D2 of magnetic anisotropy is provided in the radial direction of the magnet, the degree D1 being strictly higher than the degree D2.
