Erosion failure mechanism of EB-PVD thermal barrier
Dec 15 2017 · In an actual erosion process the stress waves generated by a particle impact are not expected to reflect back to the impact site. However because of the limited size of the SEM image the elastic stress wave reflections from the outer boundaries may affect the erosion process .In order to minimize such an effect the width of the model was expanded to 370 µm along the x direction.
