Summary: Polycrystalline diamond (PCD) is being developed as a new cutting tool material for titanium alloy machining. The high temperature hardness of PCD can improve productivity by enabling higher cutting speeds. This study examines the performance of different PCD tool grades in milling Ti-54M, and finds that smaller grain size offers better tool life due to superior fracture toughness. The study also compares the surface integrity of PCD and carbide machining, and shows that PCD results in lower microstructural damage and cutting forces.

Summary: In the past three decades, surface texturing has been extensively studied as a method to control friction and wear in tribological systems. Surface textures reduce friction by lowering adhesion, reducing effective contact area, and collecting wear particles. The effect of laser parameters on the machining performance of textured tools is still not well understood. In this research, linear textures were fabricated on carbide tools using the Nd: YAG laser with varying parameters, and the effect of parameters on texture depth, resolidified layer, and substrate hardness was evaluated. The textured tools showed improved machining performance in turning pH 13-8 Mo SS alloy, with reduced cutting forces, temperature, surface roughness, and tool wear. The textured tools fabricated with fluence = 31.4 J/cm2 and pulses per surface spot = 5 pulses/surface spot outperformed other combinations of laser parameters.

Summary: Nickel-based superalloy is a critical material in aerospace for turbine engine components, but its poor machinability and low efficiency hinder its wide use. Cubic boron nitride (cBN) is a potential candidate with extreme hardness and inertness to process superalloys. This study systematically investigated the wear characteristic of cBN at different cutting speeds during the dry turning of Inconel 718 through experiments and FEM simulations. The effects of cutting speeds on cBN tool life and wear mechanisms were examined, and FEM simulations analyzed the influence of tool wear on the cutting edge temperature field and surface layer stress distribution of Inconel 718.

Summary: The research involves the development of a wear model integrated with the FEM model to predict cutting force, tool wear, and cutting zone temperature in the machining of titanium alloy. Experimental work and numerical study were conducted to vary tool nose radius, cutting speed, and feed rate. Both experiment and simulation results showed that the least cutting force was produced at the lowest feed rate and smallest nose radius. The cutting zone temperature increased with an increase in tool nose radius, and the maximum tool wear was observed at the minimal tool nose radius.

Summary: This paper investigates the friction and wear behaviors of two types of polycrystalline diamonds against different materials. The results show that increasing surface roughness leads to an increase in coefficient of friction. The coefficient of friction and wear rate of ceramic Si3N4 balls are generally lower than those of steel GCr15 balls, except for one type of polycrystalline diamond. Transfer films of SiO2 and its hydrate are observed at the friction interface, which contribute to smoother friction and wear. Carbon-based transfer films are also identified, mainly catalyzed by residual cobalt in the polycrystalline diamonds, leading to a phase transformation.

Summary: A single-beam Z-Scan experiment was conducted to investigate the nonlinear optical absorption and optical limiting properties of Bi2O3, rGO/Bi2O3, Bi2O3/WO3, and rGO/Bi2O3/WO3 nanostructures. The results showed that the synthesized nanostructures exhibited varying levels of nonlinear absorption, with bismuth-based nanostructures showing the lowest optical limiting threshold and a higher two-photon absorption coefficient. The presence of rGO contributed to the extended conjugation for charge transfer, while the strong UV-Visible absorption of Bi2O3 and WO3 led to a unique nonlinear optical response.

Summary: The recent observations of superconductive-ordering in carbon-based systems consisting of rhombohedral stacking-faults, trilayer graphene (ABC-stacks) or dislocation-rich interfaces (pyrolytic graphite) have attracted significant attention. In this study, an unusual nucleation of rhombohedral stacking-faults in low-dimensional systems comprising of multiwall carbon nanotube (CNT) buckypapers was reported. The presence of sulfur doping resulted in a broad-band at the Raman shift from 1800 to 2000 cm(-1), indicating contributions arising from disorder-rich regions with rhombohedral stacking-order (ABC-stacks). These observations were further supported by X-ray diffraction and Rietveld refinements.
