A novel ultrasonic technology is developed to monitor the LPCS coating formation in real time. The multi-channel ultrasonic matrix transducer installed at an opposite sheet side generates the sound waves which penetrate both the plate and coating. The waves reflect off the substrate-coating interface and coating surface in the direction perpendicular to the plane of the plates. The pulse repetition is high enough to generate a picture showing the coating in various areas of the coating path , and its evolution. Additionally, acoustic noise generation, an accompanying effect produced during LPCS, is examined. It is shown that spraying parameters strongly affect the thickness, microstructure and strength of coating, and in situ monitoring technique for coating process allows to control the coating performance.
Summary: A novel ultrasonic technology is developed to monitor the LPCS coating formation in real time.
