Abstract

El objetivo de este artículo es analizar el efecto de la oxidación térmica en el cambio microestructural de propiedades mecánicas de la aleación Ti6Al4V.  Las muestras de titanio fueron sometidas a tratamiento de oxidación térmica entre 450°C y 850°C por espacio de 2 horas y enfriamiento lento. La morfología superficial fue analizada mediante Microscopía óptica, Microscopía electrónica de barrido, Difracción de rayos X y Análisis de dureza. Con la oxidación térmica se generó una película de óxido tipo TiO2, la cual incrementó su espesor con la temperatura, de igual forma con este aumento de temperatura la dureza del material aumentó en un 40% a 850°C con respecto al material sin tratamiento. Los resultados además mostraron que a partir de 800°C ya se muestra en su totalidad estructuras de rutilo en la superficie de las muestras.
