| Popis: | Magnetorheological finishing (MRF), considered as a promising polishing technique that can finish a nano-level smooth surface and free of surface or subsurface damage, has been widely utilized in ultra-smooth polishing of hard-to-machine materials. MRF process is mainly rely on shear stress to remove material. In this study, α-cellulose used as an additive agent to improve the rheological properties of magnetorheological polishing slurry (MRPS). The rheometer measurement results and polishing results showed that: (1) α-cellulose can enhance the shear stress of MRPS, but increased the apparent viscosity of MRPS. (2) α-cellulose can effectively improve the stability of MRPS, when the weight fraction of α-cellulose was 0.6 wt%, both stability and internal uniform of MRPS can be obtained. (3) If the weight fraction of α-cellulose was bigger than 0.6 wt%, the machining ability of MPRS was stable and the smooth polished surface can be obtained. |
