| Abstract: | Based on the developing of reference test blocks with good and bad bonds,and on the series of delay probe and focusing probe,the ultrasonic testing techniques for the combination quality about the Babbitt metal with backing were realized via adjusting the detection sensitivity in the bonding interface of alloy with backing.The results showed that this technique could detect the alloy joint surface with minimum thickness of 1 mm,and it could quickly identify and locate the part of bad bondage. |
