Title: substitute chemical for electropolishing of deformed steel samples
Post by: ashvinfpm on January 09, 2008, 09:13:45 AM

i am doing my project work on IF steels , for that i have to do XRD of deformed steel sample. these sample should be electropolished .
 
can i do XRD of that sample without electropolishing treatment ?

Is there any chemicals for removing the protruding parts of a surface of the sample?

i have already done etching of that sample.

XRD is usually done with powders....Powder diffraction?  You are going to have to powder the material.  The powder must be homogeneous. 

With XRF you will not have to powder the steel. 

If the electroplating is part of the sample matrix....part of the final product...then the electroplating must be done prior to the powdering and XRD analysis.  In XRD you must have  a representative sample....it must be homogeneous.  The prep has to be done in such a way that the tru directionality of the material is preserved.  It cannot be biased directionally.

You cn lathe, sand, grind, crush, sieve, ....there are so many techniques

MY BAD..you said elctroPOLISH.....that is just a way of removing surface imperfections.

I imagine that you can do the XRD prior to POLISHING!!!!
