Abstract
An ultrasonic transducer assembly, having a cobalt-base alloy housing with at least one planar wall section, and at least one ultrasonic transducer mounted to the planar wall section, the ultrasonic transducer operatively arranged to impart an ultrasonic vibrating force to the planar wall section of the housing.
Claims8
An ultrasonic transducer assembly, comprising:
- a cobalt base alloy housing having at least one planar wall section;
- at least one ultrasonic traducer mounted to said planar wall section, said at least one ultrasonic transducer operatively arranged to impart an ultrasonic vibrating force to said planar wall section;
- a first transducer member;
- a second transducer member;
- a pair of piezoelectric crystals positioned atop one another and sandwiched between said first and second transducer members;
- a first electrode electrically connected to said crystals;
- a second electrode electrically connected to said crystals, wherein said pair of piezoelectric crystals are operatively arranged to impart an ultrasonic vibrating force to said first and second transducer members when a voltage is applied across said first and second electrodes;
- and,
- a stainless steel braze mass operatively arranged to be brazed to said cobalt base alloy housing, said braze mass having a first planar surface to be secured by brazing to said housing and having a second planar surface parallel to said first planar surface, said second planar surface operatively arranged to be secured to said second transducer member, wherein said second planar surface becomes concave in shape after brazing.
