Abstract
PURPOSE: To obtain excellent transmission of ultrasonic waves and to make easy handling, by using water solution in which polyvinyl alcohol and plasticizer are contained as the major components, for the contact medium for ultrasonic crack detection and thickness measurement.
CONSTITUTION: Polyvinyl alcohol PVA, plastic such as glycerin of 30 to 200wt.% to PVA, and rust-proof agent such as sodium polyphosphate and antiseptic such as sorbic acid of 5 to 15wt.% of PVA are dissolved in water. Further, to the extent that the film forming ability of contact medium is not lost, the thickner such as starch can be added, and the viscosity in use with the inspection is preferrably within 1000 to 8000cp.
