“…In dry slip conditions, wear can be described as a phenomenon occurring at the interfaces of the interacting bodies [20]. The technological revolution has given rise to cutting-edge engineering products encompassing highspeed sliding, rolling, or small-dimensional geometric shapes designed to withstand harsh and challenging environments.…”

This work includes preparing and studying a transparency polymeric coating that has good tribological and mechanical properties. Coating enhanced with nanoparticles can absorb UV radiation while keeping transparency. Also, coating leads to lowering the friction coefficient that improves the coating's wear resistance performance for mobile and computer screen applications, also it leads to increasing the life span of car lamp covers and glass, plastic windows and coating of solar cells. The nanocomposite coating consists of Graphene oxide (GO), Graphene oxide modified (MGO). Composite coating samples with GO and MGO nanoparticles at various weight percentages (0, 0.25, 0.5, and 1 wt%) were created by employing a solution mixing process. Scanning electron microscopy (SEM) was used to evaluate the distribution of nano and fracture failure. Hardness, DSC, wear and scratch tests were done. Additionally, the relationship between tribological and mechanical behavior was studied, as well as the mechanical properties of PMMA nanocomposites coating with the nanoparticle addition. The results showed that adding GO, MGO nanoparticles enhanced the PMMA's tribological performance. It was discovered that PMMA nanocomposites coating had a lower wear and friction coefficient than pure PMMA coating. According to the microstructure data, the ultrasonic treatment significantly contributed to the nanoparticles' good dispersion and decreased agglomeration. The results of mechanical qualities, such as hardness, demonstrated a discernible improvement..

Surface changes of biomaterials are essential for aligning with the biological system’s dynamics and enhancing the effectiveness of bioimplants. Customized surface alterations based on the material’s bonding ability, biocompatibility, and interactions with host cells may have a substantial impact. This investigation uses hydroxyapatite (HAp) with 0, 10, 20, 30, and 40 wt% silver as a thin coating layer on stainless steel (SST) 316 L by electrophoretic deposition preparation at 30 V and 30 min coating duration. The coating’s crystallinity, morphology, and microstructure have been investigated using structural characterization methods such as X-ray diffraction, Scanning electron microscopy, and energy dispersive spectroscopy. The resistance to corrosion of uncoated and coated SST substrates has been assessed using potentiodynamic polarization experiments. The results show that the HAp-nanosilver coating layer increases the SST’s resistance to corrosion in Ringer solution. The HAp 10% silver-coated SST displays a reduction in corrosion current density. These further demonstrate the potential for using HAp and silver-coated stainless steel as a surgical instrument to increase biocompatibility and resistance to corrosion.
