Abstract

To overcome the disadvantages such as precision of orientation difficult to assure

device regulation consuming time

and low examination efficiency etc existed in the laser thickness measurement system used at present

the eddy current nondestructive evaluation method and strategy for the coating thickness measurement was proposed which provided an effective evaluation tool for thickness measurement of stainless steel contoured structure coating.By using the numerical simulation

the applicability of Eddy Current Testing Technique to thickness measurement of coating in a steel pipe was investigated.A method of probe lift-off was proposed

which was based on database.A wide range sensor was designed and the difficulties of narrow measuring range

low precision

the influences of curvature and thickness on the probe signals and nonlinearity of eddy current signals were solved.The simulation results show that the measure precision of the eddy current sensor for liftoff can reach 0.01 mm

when using Eddy Current Testing Technique to test the thickness of the steel pipe which coating thickness of inner wall is 10 mm

which could meet the demands of practical engineering.
