I would like to etch a sample made of nickel and 420 martensitic stainless steel. What is the best solution and immersing time for this purpose? In the case of electroetching, what solution, immersing time and current density would be suitable?
Dear Dr. Farid Movassagh-Alanagh,
for your purpose, I suggest you to try Marble’s Etchant:10 g CuSO4, 50 ml HCl and 50 ml H2O. Immerse or swab for 5-60 seconds.
How to can see in the following references, it should work for both proposed materials:

I would try EBSD to visualize the microstructure without etching, if Marble's echant do not work! ;)
Dear Paul Rosemann I do not want to etch my sample for characterization. It will be etched to being coated.
