Summary: The material removal process of magnetorheological foam plane finishing (MRFPF) method considering various processing conditions was investigated. A material removal rate (MRR) model based on the updating type of workpiece moving trajectory, magnetic field distribution, and polishing speed in the polishing area was established. The MRR is generated by integrating the polishing pressure and speed over the time that polishing pressure on the workpiece updating for 1 cycle, with a relative error between theoretical and experimental results less than 11.63%. Moreover, MRFPF can achieve much higher MRR and surface flatness improvement rate than that of magnetorheological finishing (MRF) under different processing conditions, indicating the effectiveness of MRFPF in planar finishing.

Summary: This study aims to research the material removal mechanism of non-resonant vibration-assisted magnetorheological finishing (NVMRF) of SiC ceramics for improving their surface quality and finishing efficiency. A theoretical model of the polishing forces considering the vibration was proposed, and a theoretical model of material removal rate (MRR) based on the Preston equation was proposed for quantitative analysis. Furthermore, a theoretical model and the smoothed-particle hydrodynamics (SPH) simulation of a single diamond abrasive were proposed to explain the reasons for the increase in the MRR. Combined with designed processing experiments, introducing the vibration can enhance the normal force and total shear force, leading to improvement in the MRR, surface quality, and subsurface damage (SSD).

Summary: This report demonstrates that the particle temperature and velocity in plasma sprayed alumina coatings have a significant impact on the microstructure, mechanical properties, and residual stress depth profile of the coatings. Increasing the particle temperature results in a substantial increase in hardness and indentation modulus, while increasing the particle velocity reduces the coating porosity. The mechanical properties are strongly influenced by the coating porosity. Additionally, an increase in particle temperature leads to an increase in tensile residual stress in the coatings, and there is also partial recovery of the grit blasted compressive substrate during spraying.
