This document reviews surface quality evaluation in electrophoretic deposition assisted polishing (EPDAP) of steel and other materials. EPDAP is a recent polishing technique that can generate surface finishes on the nanometer scale, improving part life. Surface quality in EPDAP depends on parameters like polishing time and speed, abrasive size, voltage, and load. Literature on EPDAP of materials like stainless steel, ceramics, and carbon nanotubes is summarized. Studies show EPDAP can reduce surface roughness Ra to under 0.1 μm for various materials. Parameters like time, load, speed, and abrasive size must be optimized to minimize roughness. EPDAP is capable of producing very smooth finishes for
