Uncertainty Evaluation of Indication Error of Ultrasonic Coating Thickness Measurement

  • 摘要: 为了判别超声波涂层测厚仪检测结果的可信度,对该仪器的示值误差测量不确定度进行了评定。结果表明:该测厚仪示值误差的最佳估计值为19.8 μm,不确定度为21.9 μm,且由仪器精度引入的不确定度分量对仪器示值误差的不确定度影响最大。
    Abstract: Ultrasonic Thickness Measurement was widely used in processing and testing of parts for quality control. The uncertainty evaluation was significant in the indication Error. The uncertainty evaluation of indication error of ultrasonic thickness measurement was undertaken. The results show that the best estimate of Indication Error of the measurement was 19.8 μm and the uncertainty was 21.9 μm. Furthermore, the uncertainty of instrumental precision makes the greatest contribution to the uncertainty evaluation.
