COATING INFLUENCE ON ULTRASONIC THICKNESS MEASUREMENT RESULT
In this paper the Monte Carlo Simulation is presented and applied as a method for quantification of the coating influence on ultrasonic thickness measurement (UTM) results. UTM as a Non Destructive Testing (NDT) technique is commonly used for integrity assessment of components and the whole structures. It belongs to a field of measurement activities since the measurement result is shown quantitatively. Generally, a measurement result is complete only when it is followed up by a statement of the associated uncertainty. In order to evaluate the measurement uncertainty of ultrasonic thickness measurements all significant factors and their interactions should be taken into account. One of the influence factor is coating over the base material. In some cases the coating can be removed before the beginning of measurement procedure, but in some cases the measurement should be conducted through the coating. In this paper the coating influence on ultrasonic thickness measurement result was analysed and quantified by measuring the thickness of base material over the coating in repeatability conditions. In order to investigate the coating thickness impact of measurement component, measurements were conducted on prepared test specimen of steel. Extended measurement uncertainty of selected ultrasonic thickness measurement system was estimated.
