Three different etching methods are used to uncover the ferrite-austenite structure and precipitates of secondary phases in stainless steel 22.5% Cr – 5.4% Ni – 3% Mo – 1.3% Mn. The structure is studied under a light microscope. The chemical etching is conducted in a glycerol solution of HNO3, HCl and HF; the electrochemical etching is conducted in solutions of KOH. The Small Business section of your local Environmental Protection Agency offers free advice on the safe disposal of exhausted metal salts and liquid ferric-based etching solutions. Solid zinc, aluminum, steel and copper residues may be safe for local disposal once any copper sulfate content has been fully removed.
Whether you put the steel plate in the etching acid face-up or face down, suspend it off the bottom of the container in some fashion. (This is particularly necessary when the plate is face down.) Tap the container holding the chemical bath periodically to keep the solution agitated. 6. Remove and clean the steel plate. Electro-Etching.
