Surface Microscopic Characteristics Analysis on Electrochemical Mechanical Finishing of Stainless Steel in NaNO3 Electrolyte


Article Preview

The mechanism of electrochemical mechanical finishing (ECMF) process was investigated. The ECMF experimental system and control unit were developed and some vital procedure parameters such as operating voltage, electrolyte component and concentration, machining temperature, electrode gap and current density were also evaluated and optimized, then the optimal procedure parameter match was obtained. Furthermore, the important surface roughness characteristics before and after ECMF process such as height and spacing characteristics of surface roughness, surface waviness characteristics, surface microscopic appearance and light reflection characteristics were compared. The experiment and measurement results indicate that ECMF process can distinctly improve surface quality, eliminate the surface scratch marks and defects and reduce surface roughness.
