ACOUSTIC EMISSION ANALYSIS FOR CONTINUOUS MONITORING OF THERMAL SPRAY PROCESSES

该方法的可行性研究为基于涂层过程声发射的低温热喷涂过程在线无损监测技术的发展奠定了基础。主要目标是：识别热喷涂过程AE中包含涂层质量信息的元素;连续在线监测涂层过程，以便及早发现并及时纠正与最佳喷涂条件的偏差;与不充分的喷涂后质量检查相比，大大减少了产品拒收和重新涂覆。

The proposed feasbility study is to lay the ground for the development of a novel on-line, non-destructivemonitoring technology for the low temperature thermal spray processes based on the acoustic emission (AE)during the coatings. The key objectives are: identification of the elements in the AE of the thermal sprayprocess that contain information about the coating quality; continuous on-line monitoring of the coatingprocess so that deviations from the optimum spraying conditions can be detected early and correctedpromptly; greatly reducing product rejections and re-coating compared to the inadequate post-spray qualitycheck.
