Non-destructive detection of coating thickness is important after coating deposition and
during service. The present work is to establish a measurement method for fast inspection …

Most methods used to measure the thickness of thin liquid or solid surface films and coatings
need access to the coated surface. In this work reflected ultrasonic pulses were used to …

A thick ZrC layer was successfully coated on top of a SiC buffer layer on carbon/carbon
(C/C) composites by vacuum plasma spray (VPS) technology to improve the ablation …

The thickness of the optically translucent coating was evaluated using the transmission
thermography. The transmitted temperature of a two-layer structure was theoretically …

Porosity is considered as one of the most important indicators for the characterization of the
comprehensive performance of thermal barrier coatings (TBCs). In this study, the ultrasonic …

The thickness of the thermal barrier coating (TBC) has an important impact on the thermal
insulation performance and in-service life. The TBC consists of multiple coatings layers in …

随着金属增材制造工艺的工业化应用, 涂层成形过程中残余应力及其超声无损检测技术日益受到
