Gyrolaser comprising a device protecting against corrosion
The gyrolaser has a light unit (1) including a set of openings (4a). A set of electrodes (5a, 5b) is placed in the openings of the light unit. A set of joints (6) is arranged to ensure tightness of the light unit levelled with the set of openings. A sacrificial electrode is in contact with the joint...

| Abstract | The gyrolaser has a light unit (1) including a set of openings (4a). A set of electrodes (5a, 5b) is placed in the openings of the light unit. A set of joints (6) is arranged to ensure tightness of the light unit levelled with the set of openings. A sacrificial electrode is in contact with the joints. The sacrificial electrode includes oxyreduction potential that is than lower oxyreduction potential of the joints. The sacrificial electrode is not placed between the light unit and the joints and is not placed between electrodes and the joints.
L'invention concerne un gyrolaser qui comprend un bloc optique (1) comprenant un premier matériau vitrocéramique comprenant des ouvertures (4a), des électrodes (5a ; 5b) placées dans les ouvertures (4a) du bloc optique (1) et des joints (6) assurant l'herméticité du bloc optique (1) au niveau des ouvertures (4a). Le joint (6) comprend de l'indium d'un premier potentiel d'oxydoréduction (E° 1 ). Le gyrolaser comprend en outre en contact avec le joint (6) au moins une électrode sacrificielle (7) comprenant un deuxième matériau d'un deuxième potentiel d'oxydoréduction (E° 2 ), le deuxième potentiel d'oxydoréduction (E° 2 ) étant inférieur au premier potentiel d'oxydoréduction (E° 1 ). |
