Summary: Digital image processing can be used to identify and quantify wear mechanisms in various fields. In this study, images of a worn brass material were obtained using a metallurgical inverted microscope. The images were processed using adaptive Otsu's global thresholding and granulometry methods to detect wear shapes. The results showed that wear can be quantified and identified using digital image processing, eliminating the need for expensive instruments like scanning electron microscopes.

Summary: This study focuses on the production of pellets composed of alumina and cerium oxide abrasive grains, bonded with a pitch organic binder matrix, which exhibit high wear resistance and longevity to improve the quality of optical surfaces. The combination of raw materials and experimental protocol used allowed for cost-effective and environmentally-friendly production of these pellets. Results indicate that the pellets have a uniform internal structure and significant porosity, leading to increased lifetime and improved transmittance of optical surfaces.

Summary: This study examined the abrasive wear of polymer composite coatings based on polyether ether ketone (PEEK) and aromatic thermosetting co-polyester (ATSP) in a lunar regolith simulant environment. The results showed that the polymer-on-polymer system had a significant reduction in friction and effectively mitigated the accumulation of sand and dust at the interface.

Summary: The aim of this study is to evaluate the bioactive and tribological properties of the MgO doped borophosphate glass system. The addition of MgO promotes degradation of the glass and increases its bioactivity. In terms of tribological properties, the glass sample with 3% MgO exhibited the highest hardness and the lowest wear rate. MTT assay confirmed the non-toxic behavior of the glass samples. Therefore, MgO doped borophosphate glass shows potential for bone filling and wound healing applications.

Summary: In this study, waste fly ash powder-filled chopped glass fiber reinforced epoxy composites were fabricated and analyzed for physical, mechanical, thermo-mechanical properties, and three-body abrasive wear rate. The results showed improvements in density, void fraction, and hardness with increasing fly ash content, while strength and modulus increased up to 10 wt.%. Dynamic mechanical analysis was used to evaluate homogeneity of composites, and Taguchi's design of experiment method was employed to analyze the effects of various factors on composite properties.

Summary: The study evaluated the abrasive wear resistance of NiCrBSiFeC coatings with 40% SiC added through flame spray process. Surface and cross-sectional characterization was performed using SEM, EDS, and XRD. The results showed that remelting decreased porosity and increased microhardness, while SiC reinforcement reduced mass loss with non-remelted coatings having the least loss.

Summary: In this study, bioactive behavior of borophosphate glasses containing different Ta2O5 contents was investigated by immersion in simulated body fluid. The results showed that an increase in Ta2O5 content resulted in a decrease in the intensity of hydroxyapatite diffraction lines, indicating a decrease in bioactivity. It was also found that the glass containing 3 mol% Ta2O5 had the lowest weight loss after immersion in simulated body fluid. These Ta2O5 borophosphate glasses exhibit bioactive nature and have potential applications in bone healing and drug delivery.

Summary: This study investigates the effects of EDM parameters on the tribological performance of recast layers, including wear depth, friction coefficient, friction force, and contact surface temperature. The results demonstrate that it is possible to control the tribological performance of recast layers by varying EDM parameters, thus reducing the time and costs required for surface treatments after machining.

Summary: This study explores the use of porous nano activated carbon materials derived from waste biomass as reinforcements in epoxy composites. Results show that the inclusion of activated carbon enhanced the wear resistance of composites, with the lowest wear rate observed in composites with 2% filler loading. Regardless of the filler content, all composites displayed semi-ductile erosion wear behavior, with the 2% activated carbon epoxy composites showing the best abrasive wear resistance on the P800 abrasive surface.

Summary: This study examines the utilization of biomass solid waste in the form of Tamarind Seed and Date Seed Fillers to reinforce polymer composite materials. The inclusion of these hybrid fillers enhances mechanical properties while having a minor impact on thermal properties. The findings suggest that these composites may be suitable for cost-sensitive applications with some compromises in thermal qualities.

Summary: This study evaluated the mechanism of material removal with the help of mechanically mixed layer, focusing on aluminium matrix alloy and its composite. The investigation found that the composite had better hardness and wear resistance than the alloy, with a mechanically mixed layer forming under low load but not under high load. The maximum wear resistance was observed for fine abrasive and low load conditions, with a transition in material removal for high abrasive sizes.

Summary: The role of graphene nanoplatelets (GNPs) in enhancing the physico-tribological properties of mahua oil was investigated, showing a significant decrease in coefficient of friction and wear scar diameter. Different loadings of GNPs had varying effects on the extreme pressure characteristics (EPC) of mahua oil, with 0.1 wt.% loading identified as the best for wear perspective. The morphology of EPC revealed severe abrasion and metal squeeze out on the contact surface.
