Magnetically Assisted Abrasive Finishing (MAAF) processes are most suitable for obtaining quality finish on plane, internal and external cylindrical surfaces of metallic as well as non-metallic materials. These products are highly demanded in modern industrial applications. In spite of remarkable results of MAAF processes, the major constraint towards wide spread use of this technology is the n...

Abstract Background This study aims to investigate the influence of different dentin pretreatment procedures on resulting abrasive wear. Methods Two groups (A, B) 60 samples each were prepared. Group A was brushed with an slurry (RDA = 85) and group B a 174). Four subgroups in (n 15) created (A1–A4) (B1–B4). The pretreated as follows: A1 + B1 1200-grit grinding paper, A2 B2 1200- 2000-grit pape...

Diamond needs to have a perfectly smooth surface due the growing requirements in fields of electronic semiconductors, optical windows and high-fidelity loudspeakers. However, polishing diamonds is highly challenging their exceptional hardness chemical stability. In this study, new slurry prepared for proposed photocatalysis-assisted mechanical (PCMP) approach obtain an ultra-smooth large-area d...

14 15 The catalytic activity and durability of 2 wt. % Pd/Al2O3 in powder and washcoated on cordierite 16 monoliths were examined for the liquid phase hydrodechlorination (LPHDC) of polychlorinated 17 dibenzo-p-dioxins/polychlorinated dibenzofurans (PCDD/Fs). NaOH was employed as a 18 neutralizing agent, and 2-propanol was used as a hydrogen donor and a solvent. Fresh and spent 19 powder and mo...

In this work, TiN/Ti(C,N)/Al2O3 multilayer coatings were deposited using an industrial-scale thermal CVD system. Two polymorphs of Al2O3, the stable α- and metastable κ-Al2O3, obtained by deposition specific bonding layers at Al2O3/Ti(C,N) interface. The comparable hardness elastic moduli κ-Al2O3 measured. tribological behavior Al2O3 was studied room temperature 24CrMoV5-1 balls; friction coeff...
