Investigations and Applications of UT in Evaluation of Coating Quality in Remanufacturing

By the technology of remanufacturing and confectioning, the resource was saved and the operating life of production was prolonged, so the definition of remanufacturing was introduced. In order to guarantee the quality and the property of the remanufactured products, the evaluation of which was obligatory and important. Because the nondestructive testing(NDT) is befitted to evaluate the remanufacturing production, so the investigation, questions and the trend in development of the application of NDT in remanufacturing coating were expounded in this paper.
