SuperSoniX – A new UT Couplant with a Historic Name

2019-01-24
In May of 1940, Floyd Firestone, a Professor in the department of Physics at the University of Michigan, filed US patent 2280226 in which he described an instrument for the detection of flaws and measuring thickness in metal objects. Dr. Firestone used the term “Supersonic Vibration Waves” to describe what we now refer to as pulse-echo Ultrasound Testing (UT).

The term “Supersonic Inspection” was used in reference to UT officially until the first manned aircraft flight by USAF Captain Chuck Yeager exceeded the sound barrier of 768 mph in October of 1947. Captain Yeagers flight in the Bell X-1 “Rocket plane” became known as supersonic flight. Gradually the term Ultrasonic Testing replace d Supersonic Testing in NDT.

Echo UltraSonics new water-based gel couplant, SuperSoniX, is named in honor of Dr. Firestone and his work which gave rise to our world of UT.

SuperSoniX is our third-generation acrylic polymer water based couplant that improves on the electrolyte stability and reduces the tendency for the polymer to collapse when exposed to corrosion or marine salts. In practice this means less reapplication of couplant during a test procedure, especially on objects that are exposed to the environment.

SuperSoniX offers several benefits, including; a broader operating range, a slower evaporation rate, a longer drying time, improved stability against corrosion salts and is environmental and operator friendly.

While many couplants will couple sound and perform adequately for the same inspection, often one will deliver performance that will make a significant improvement on inspection reproducibility and defect detection (the #1 goal of UT). The right couplant can minimize couplant re-application during an inspection, reduce total time for the inspection and lower cost. Let us recommend the most appropriate couplant for your application and temperature range.
