Atomistic study on the effect of the size of diamond abrasive particle during polishing of stainless steel [PDF]

open access: yes, 2023
Nanofinishing or polishing helps to reduce surface roughness, which further improves both the optical and chemical properties of engineering materials. During the polishing of any engineering material, the size of abrasive particles plays a significant ...

Magnetorheological brushes – Scarcely explored class of magnetic material [PDF]

open access: yes, 2023
Magnetic materials such as magnetorheological (MR) fluids, and magnetorheological elastomers exhibit a broad change in their material properties, for example, viscosity and storage modulus in the presence of a magnetic field.

Analysis of tool-mass-acceleration effects onto sub-aperture computer controlled polishing (CCP) [PDF]

open access: yes, 2016
Although computer controlled polishing (CCP) of aspheres and freeforms is one of the best understood state-of-the-art fab processes today, there are yet some unsolved issues: e.g. compared to bonnet polishing, fluid jet polishing is taking less iteration

Three Dispersed Magnetorheological Fluids in Dampers for Manufacturing Applications [PDF]

open access: yes, 2021
Magnetorheological fluids (MRFs) are included in the class of “smart materials” since their viscosity can be quickly and reversibly changed upon the application of an external magnetic field.

Analysis of infrared optical polishing effluents and reduction of COD and TSS levels by ultrafiltration and coagulation/flocculation [PDF]

open access: yes, 2014
Samples of polishing effluent produced during infrared optics manufacture were analyzed. Their particle size, composition, Zeta potential, chemical oxygen demand (COD), total suspended solids (TSS), and settleable solids were determined.
