“…Besides, research has showed that SPS offers rapid densification with negligible grain growth, better interfacial bonding of the matrix and reinforcing phases, it required short dwell time to achieve 116 effective homogeneity in composite, it is cost effective and energy efficient technique. 68,122,123 And researchers like Schwertz et al, 122 Adesina et al, 124 Adesina et al, 125 Tanaka et al 10 have reported widely on the consolidation of polymers and polymer composites using SPS technique as can been seen in Figure 14 126 and Figure 15, 10 though optimizing the PI nanocomposites properties using SPS have rarely been reported. The Spark plasma sintering (SPS) also known as pulsed electric current sintering (PECS) 123 is a sintering technique, which utilizes uniaxial force and a pulsed (on-off) direct electrical current (DC) under low atmospheric pressure to perform high speed consolidation of powder.…”

In recent years, advancements on improving the mechanical and tribological properties of polyimide nanocomposites have remarkably increased, owing to the fact that polyimide nanocomposites exhibits lightweight, high strength, thermal stability as well as anti-wear and solvent resistance. The polyimide nanocomposites are described as material of polyimide matrix reinforced with certain volume or weight percent concentration of nanofillers. Researchers have demonstrated the importance of thermoplastic polyimide nanocomposites in mechanical, thermal, and tribological applications. However, the nanocomposites are reportedly facing interfacial adhesion issues and surface properties degradation, which have affected their mechanical, friction, and abrasive wear resistance for tribological applications. Although, much advancements on improving the mechanical, thermal, and wear resistance properties of polyimide nanocomposites has been reported. However, this review summarizes the effects of nanofillers, such as carbon nanotubes (CNTs), graphene (GN), graphene oxide (GO), boron nitride (BN), molybdenum disulfide (MoS2), silica (SiO2), titania (TiO2), alumina (Al2O3), carbon fibres (CF), aramid fibre (AF), glass fibre (GF), zinc dioxide (ZnO2), zirconium dioxide (ZrO2), silicon nitride (Si2N4), and carbon nitride (C3N4) on the mechanical, thermal, and wear properties of polyimide nanocomposites for tribological applications. The authors concluded the review study with advancement, challenges and suggestions for future improvement of polyimide nanocomposites as friction component material. Thus, the review offers an insight into the improvement and selection of polyimide nanocomposites material for mechanical, thermal, and tribological applications. More so, the review will also give away for further research.

“…La deformación en frío y la dispersión del refuerzo en la matriz endurecen al material y comienza el proceso de fractura, en la última etapa se alcanza el estado estaciona-rio donde los procesos de soldadura y fractura se equilibran. Cabe mencionar que las partículas de refuerzo pequeñas, duras y frágiles actúan en la mezcla como pequeños agentes de molienda, , reduciendo así el tiempo de molienda necesario para alcanzar el estado estacionario [5].…”

“…En este trabajo los polvos de aleación A356 su obtuvieron mediante el Proceso de Electrodo Rotatorio (REP) [5], que es un método de atomización centrífuga cuya finalidad es obtener partículas o polvos metálicos de un tamaño promedio de alrededor de 200 m, con un rango entre 50 m y 400 m. El polvo metálico producido por este proceso es casi libre de porosidad comparado con los que se producen por atomización por gas, además de ser un proceso muy limpio, ya que la fusión es libre de contacto evitándose reacciones no deseadas.…”

RESUMEN Se estudia el efecto del tiempo de molienda sobre el tamaño de cristalito, la microdeformación y la microdureza Vickers, de una aleación de aluminio A356 (Al-7% en peso Si) con y sin refuerzo de SiC (15% en peso). Los polvos de la aleación metálica se obtuvieron por el método del electrodo rotatorio (REP) a partir de cilindros de la aleación, los polvos obtenidos son de morfología esférica con un tamaño promedio de 150 µm y una microdureza promedio de 94 HV0,1. La aleación con y sin refuerzo fue sometida a molienda mecánica (MM) en un molino de alta energía SPEX 8000D con tiempos de molienda efectiva de 3, 6, 9 y 12 horas. El seguimiento de la evolución microestructural de las muestras obtenidas se realizó por medio de difracción de rayos X, microdureza Vickers y microscopia óptica. Se observa que los valores de microdureza de la aleación con y sin refuerzo para 3 horas de molienda son muy similares; a mayores tiempos de molienda, las muestras reforzadas con SiC alcanzan valores superiores a los de las muestras sin reforzamiento. Este aumento en la microdureza es logrado gracias a la distribución homogénea de las partículas de refuerzo, el endurecimiento por deformación de la matriz metálica y el refinamiento microestructural, producto de la MM. Se aprecia que el compósito alcanza un tamaño de cristalito algo menor que en el caso de la aleación, sin embargo, ambos muestran un comportamiento similar. El tamaño de cristalito presenta un rápido decrecimiento durante las primeras horas de molienda para luego mantenerse casi constante.

Metal Matrix Composites are developed in recent years as an alternative over conventional engineering materials due to their improved properties. Among all, Aluminium Matrix Composites (AMCs) are increasing their demand due to low density, high strength-to-weight ratio, high toughness, corrosion resistance, higher stiffness, improved wear resistance, increased creep resistance, low co-efficient of thermal expansion, improved high temperature properties. Major applications of these materials have been in aerospace, automobile, military. There are different processing techniques for the fabrication of AMCs. Powder metallurgy is a one of the most promising and versatile routes for fabrication of particle reinforced AMCs as compared to other manufacturing methods. This method ensures the good wettability between matrix and reinforcement, homogeneous microstructure of the fabricated MMC, and prevents the formation of any undesirable phases. This article addresses mainly on the effect of process parameters like sintering time, temperature and particle size on the microstructure of aluminum metal matrix composites.
