WebElectron beam damage. When using a scanning electron microscope (SEM), the electron beam can, over time, permanently alter or degrade the sample that is being observed. Sample degradation is an unwanted effect as it can alter — or even destroy — the details you want to see, and consequently change your results and conclusions. WebA review is presented of those factors responsible for promoting the integrity and longterm durability of metal-polymer bonds used in the fabrication of aircraft and aerospace structures. Using a multidisciplinary approach and a variety of surface analytical techniques such as extended resolution scanning electron microscopy (XSEM), X-ray photo-electron …
