等离子喷涂金属陶瓷涂层结构完整性的声发射研究

The Study of Acoustic Emission About Plasma Sprayed Metal Ceramic Coatings in Structure Perfection

从微观结构与涂层破坏的动态过程入手,利用声发射仪跟踪涂层内部微裂纹的产生,扩展到断裂的动态过程,对研究涂层的破坏机理,以及改善涂层的性能具有实际应用的价值。

In the investigation through observing the microstructure and the fracture process, Acoustic Emission Apparatus can be used to trace changes of a coating's microcrack from initial stretching to final fracture, leading to a better understanding of the coating's breaking mechanism and the improvement of coating's properties.
