| titleOfInvention | Method for fabricating high temperature ultrasonic sensors using lithium niobate crystals brazed with gold and indium |
| abstract | The invention relates to a method for manufacturing a high-temperature ultrasonic sensor comprising an upper electrode (2) of steel or metal, a transducer (3) made of piezoelectric material, a propagation medium provided in the transducer and sound waves The steel or metal support (1) at the interface, the first junction (J 1 ) between the support and the piezoelectric crystal, and the second junction (J 2 ) between the converter and the upper electrode , characterized in that said method comprises, for producing said gold and indium joint, the brazing and diffusion operations comprising the following steps: a first step, raising the temperature to a first of between about 150°C and about 400°C temperature, and maintaining said first temperature for a first length of time corresponding to a first plateau; and a second step of increasing the temperature to a second temperature between about 400°C and about 1000°C, and causing said first The second temperature is maintained for a second length of time corresponding to a second plateau period. |
