CLAD ULTRASONIC WAVEGUIDES WITH REDUCED TRAILING ECHOES |
摘要 |
<p>Ultrasonic buffer rods are useful for on-line process control of industrial material processes at elevated temperatures. In order to increase the signal-to-noise ratio in the reflected ultrasonic waves revealing the information of the condition of the materials being processed, clad ultrasonic waveguides consisting of a tapered or uniform core and a cladding are proposed. The core is made of a low ultrasonic loss material. Preferably, the cladding has a higher ultrasonic velocity than the core. The cladding may be thermally sprayed over the core. The waveguides are simple, rugged, machinable and operable at elevated temperatures.</p> |
