i am struggling to collect the HF acid to prepare Keller's reagent.
If HF is not possible to collect, What is the alternate for HF acid to prepare the etchent for dissimilar welded joint ( Al alloy with Ti alloy)
you may choose nitric acid
pepare 20 ml H2O + 5 ml H2O2 + 10 ml KOH solution.....This might work
You can select the appropriate enchant by :-
ASM
Professor P.J.Goodhew, book on specimen preparation has got full etchants.
I want to get the clear XRD image on my samples, but i got amorphous structures. what is the problem on my samples?
