Resumen

RESUMEN

Los materiales compuestos de matriz de aluminio (MCMA) juegan un papel importante en el campo de la automoción y la industria aeroespacial debido a sus excelentes propiedades. En esta investigación, se reforzó la aleación de aluminio AA7075 con partículas de alúmina (Al₂O₃) para mejorar su dureza y el comportamiento tribológico de la aleación base. Se prepararon cuatro materiales compuestos variando el contenido (4, 8 y 12 % en peso) de partículas de Al₂O₃ mediante la técnica de moldeo por agitación. La morfología superficial de los compuestos propuestos garantizaba la distribución uniforme de las partículas de Al₂O₃ en la aleación matriz. La dureza del material compuesto se midió utilizando un durómetro Brinell y el valor máximo de dureza se encontró en el material compuesto AA7075 - 8 % Al₂O₃. Por lo tanto, se llevó a cabo una investigación tribológica en este compuesto AA7075 - 8 % Al₂O₃. La carga (P), la velocidad de deslizamiento (V) y la velocidad de deslizamiento (D) se tomaron como parámetros de desgaste para llevar a cabo los experimentos. Se aplicó una técnica de orden de preferencia por similitud a la solución ideal preferida (TOPSIS) para determinar las condiciones óptimas de los parámetros que permitieran obtener la tasa de desgaste (WR) y el coeficiente de fricción (COF) más bajos. Los resultados mostraron que el menor WR y COF se obtuvieron con ‘P’ de 15 N, ‘V’ de 1 m•s^-1 y ‘D’ de 1000 m•s^-1. Los resultados del ANOVA revelaron que “P” es el factor con la contribución más significativa (38,36%), seguido de “D” (28,32%). La morfología de la superficie desgastada de la probeta del experimento de confirmación se investigó mediante SEM y se informó del mecanismo de desgaste.
