Electropolishing of 410 stainless steel in perchloric acid solution
Electropolishing of 410 stainless steel in perchloric acid solution
Abstract
Stainless steel type 410 is widely used due to its good corrosion resistance. For further
improvement, an electropolishing process was applied to it in 15% by volume Perchloric acid.
The electropolishing process conditions were 18V for 10 minutes at two different temperature
of room and 70 c0 temperature. Potentiodynamic polarization test were applied for 410 stainless
steel specimens before and after electropolishing at both temperature . Corrosion resistance
improve for electropolishing specimen at room temperature because improve passive chromium
surface oxide layers observe at xrd analyses. AFM and surface roughness measurement were also
obtained and the surface roughness decrease for 101 to 0.45 for electropolishing specimen of
room temperature.
