The unit (1) has a ceramic element (3) adjusted against a body (5), and an engagement device (7) including a deformable intermediate part (2) to block adjustment between the ceramic element and the body. The device includes a fixing unit between the intermediate part and the ceramic element to decrease relative displacement between the intermediate part and the element. The fixing unit comprises recesses formed on the element to locally increase roughness. The recesses form a series of parallel rectilinear grooves that cross with another series of parallel rectilinear grooves. The body is made of metal. The intermediate part is made of polymer or metal. |
