In this work, the wear and friction behavior of nanoscale SiCp (1 vol.%) reinforced Mg composite were investigated. Experiments carried out by rubbing a GCr15 steel ball on surface pin specimens with different sliding velocities 0.1, 0.3 0.5 m/s at distinctive normal loads 10, 20, 30 N, respectively (without aid lubricant). Detailed analysis demonstrated that efficiently block grain growth improve mechanical properties due to refining dislocation strengthening. As result, resistance was more...
To improve the wear resistance of involute spline couplings and meet requirements lightweight design, this work focuses on PEEK (polyetheretherketone) based polymer composite with tooth surface texture. A dynamic model differential equation texture were established using concentrated mass method. The arrangement was fractal theory, a calculation method for meshing stiffness system potential energy morphology parameters, arrangement, material characteristics considered in different textured...
This study optimized the proportions of synergistic catalysts to efficiently activate potassium peroxymonosulfate (Oxone), generate more reactive oxygen species, and accelerate chemical oxidation silicon carbide (4H-SiC) wafers during chemical–mechanical polishing (CMP) for an improved material removal rate (MRR) surface quality. The Oxone was activated using ultraviolet (UV) catalysis with a photocatalyst (TiO2) transition metal (Fe3O4) enhance capacity slurry through production strong...
The bimodal size SiC particulates (SiCp) reinforced magnesium matrix composites with different ratios of micron SiCp and nano (M-SiCp:N-SiCp = 14.5:0.5, 14:1, 13.5:1.5) were prepared by semisolid stirring assisted ultrasonic vibration method. AZ31B alloy all as-cast SiCp/AZ31B extruded at 350 °C the ratio 12:1. Microstructural characterization M14 + N1 14:1) composite revealed uniform distribution significant grain refinement. Optical Microscopy(OM) observation showed that, compared M14.5...

In the present study, AZ31B magnesium matrix composites reinforced with two volume fractions (3 and 5 vol.%) of micron-SiC particles(1 μm) were fabricated by semisolid stirring assisted ultrasonic vibration method. The as-cast ingots extruded at 350 °C extrusion ratio 15:1 a constant ram speed 15 mm/s. microstructure was investigated optical microscopy, scanning electron microscope transmission microscope. Microstructure characterization showed relative uniform reinforcement distribution...
Heterogeneous composites have strong anisotropy and are prone to dynamic recrystallization during hot compression, making the mechanical response highly nonlinear. Therefore, it is a very challenging task intellectually judge thermal deformation characteristics of magnesium matrix (MgMCs). In view this, this paper introduces method accurately solve thermoplastic composites. Firstly, compression constitutive model based on stress softening correction was established. Secondly, complex...
The effect of bimodal size(nano + micron) distribution on the microstructure and mechanical properties Mg-2.8Al-0.8Zn(AZ31B) fabricated by ultrasonic dispersion method was discussed. grain refinement-degrees composites not only connect with double size distribution, but also proportion distribution. Compared to other samples, microstructural characterizations AZ31B alloy containing (4.0%micron+1.0%nano)SiC revealed presence uniformly distributed micro-SiC(SiCMP) hybridized nano-SiC(SiCNP)...
