  • Comparing the characteristics of surface-passivated and electropolished 316L stainless steel
    . When measured after electropolishing, the surface roughness of the sample had increased from approximately 1 uin. Ra to approximately 6 uin. Ra. As a result of the higher internal (lattice) energy associated with defects, the electropolishing process preferentially attacks areas that have inclusions...
