“…Grain structure was displayed with the presence of TiO 2 . Figure 6 (B & C) of composites reinforced with 1wt%, 2wt% respectively, where grain boundary clearly reveals in indication to uniform scatter of TiO 2 particles over the composite that leads to refining grains [24,25]. Minimum grain size was found with 2% addition.…”

Aluminum, as a base metal in metal matrix composites (MMCs), has favor over other traditional materials in the scopes of aviation, space, automotive and marine applications because of their improved properties such as specific strength, good corrosion resistance. Wear behavior, as a major inferiority for Al6061, was tried to be improved by adding Titanium Dioxide (TiO 2 ) particles constituting a wear resistant composite that complies with tribological uses such as brakes. Composites reinforced with weight percentages 1:5 wt% of TiO 2 with step of 1% were prepared using stir casting technique. The addition of the TiO 2 deeply affected the wear performance of Al6061 alloy where the more the percentage of the reinforcement was added, the more the coefficient of friction was elevated where reinforced composite with 5 wt% of reinforcement particles showed highest coefficient of friction. In the other hand, the reinforced composite with 5 wt% TiO 2 had the biggest wear even, in some cases, more than the unreinforced alloy, while 2 wt% TiO 2 -composite showed the lowest wear over friction process.

Se desarrolló una máquina de desgaste del tipo Pin On Ring, bajo la norma ASTM G99-17 (ASTM Int', 2018), que permite realizar ensayos mediante un procedimiento de laboratorio para determinar el desgaste de materiales. Las máquinas de desgaste tipo Pin On Ring requieren realizar pruebas a la pieza bajo ciertas condiciones como lo son: la velocidad de giro y la carga aplicada. En la máquina presentada se pueden manipular y controlar la velocidad de giro y la carga aplicada, gracias a que se incorporan los elementos necesarios para variar la velocidad del giro del motor, esto se logra a través de un variador de frecuencia, además se desarrolló un mecanismo de aplicación de carga que permite aplicar la carga deseada durante el ensayo, esta carga es medida gracias a una celda de carga que cuantifica la cantidad aplicada durante la prueba. Durante el ensayo se genera un incremento de temperatura entre las superficies, el cual se puede medir y observar su comportamiento en el panel de control de la máquina de desgaste mediante un sensor tipo k. Es posible obtener la tasa de desgaste de los materiales en contacto de manera automática, debido a que la instrumentación incorporada en la maquina permite calcular la distancia recorrida, con lo que se obtiene una idea del comportamiento del material bajo ciertas condiciones de trabajo.

Metal matrix syntactic foams (MMSF) are foam composites obtained by filling hollow and/or porous particles into a metal matrix. MMSF are promising materials in defense, aerospace, automotive, marine and engineering applications. Mechanical and physical properties of MMSF can be tailored to reach better structural and/or functional behaviors by fitting processing and tailoring parameters. Some of these parameters are: reinforcement size, volume fraction, distribution of reinforcements and chemical composition. Three techniques are available to manufacture MMSF: Stir casting/vortex method (SC), powder metallurgy (P/M) and infiltration routes. Infiltration process is by far the main employed for making MMSF, it allows a large range of reinforcement (30 vol % to 78 vol %) and offers great advantages compared to other techniques. This paper reviews infiltration routes used to date, their advantages and drawbacks, the main processing parameters of each route, and a relation of representative studies developed to date on the synthesizing of MMSF by molten infiltration processes.
