Abstract

We propose that a magnetorheological (MR) polishing fluid should be considered as a polydispersed suspension system due to its composition and appearance after sedimentation and that fluid can be divided into flocculated MR polishing fluid and deflocculated MR polishing fluid. Two kinds of MR polishing fluid are prepared using different additives, and removal function experiments are carried out on BK7 glass and a silicon modification layer on reaction-bonded silicon carbide, respectively. The performance of flocculated and deflocculated MR polishing fluid is investigated by removal function experiments. The experimental results demonstrate that performance of flocculated MR polishing fluid is superior to deflocculated MR polishing fluid in material removal rate, surface roughness, and removal function stability in long-term polishing processes.
