Ratio of viscosity to water content in solutions: A new indicator for designing of electrolytic polishing solutions for stainless steel
Abstract
Leveraging a fresh comprehension of electrolytic polishing (EP) mechanisms, this study introduces a pivotal factor - viscosity/water content ratio (VWR) - for the first time, rooted in acidity ratio theory. The present study aligns with published works to affirm the validity of the VWR indicator and its correlation with surface roughness. A noteworthy contribution lies in the design of EP solutions that can serve as a guide for stainless steels. It strikes a balance between low cost, high efficiency, long service life and desirable surface roughness. This involves regulating the dissolution-ionization-deposition process at the metal/solution interface.
