原始语种摘要: Thermal barrier coatings (TBCs) and plasma spray coatings, in general, require fine control over the deposited thickness to achieve a reliable coating performance. Currently, the plasma spray industry quantifies thickness by sampling the part before and after TBC deposition. Approximate thickness is inferred from previous runs; however, process variability can cause errors in these approximations that result in wasted time and resources that can ultimately lead to nonreliant coatings. To this end, we present an in situ optical fringe projector technology that enables coating thickness measurements across a two-dimensional surface. The sensor is capable of achieving micron scale resolution in the harsh environment of a thermal spray booth. Furthermore, unlike the existing approaches, this...
