I've been preparing 50um thick ribbon for some low angle diffraction testing, and came across a few problems. I was hoping someone heremight have some suggestions. Electro-polishing does a good job (if done very carefully) however the area which gets polished tends to be quite small. So, I ended up using a mechanical method, to reduce the surface roughness, by applying the ribbon to a small metal TEM preparation plate using resin. The only problem is that the samples, at this point, are being annealed at relatively low temperatures ie: 130 C and we had some inconsistencies with the polished samples that seem to be due to the time they are touching the still hot resin. Does anyone have any better suggestions for either the polishing method or the "gluing" of the ribbon?
