Estudio de la resistencia al desgaste por abrasión – corrosión en recubrimientos depositados mediante proyección térmica
Abstract
Se estudió la resistencia al desgaste por abrasión - corrosión de recubrimientos de Ni – Al, Ni – SiC, Ni -WC y Ni – W- Co, depositados mediante proyección térmica sobre sustratos de acero al carbono. El análisis morfológico de los recubrimientos obtenidos se realizó mediante microscopía electrónica de barrido (MEB). Para lograr el desgaste por abrasión-corrosión se suministró H2SO4 (5%Vol) durante el proceso de deslizamiento abrasivo sobre una superficie de SiC con tamaño de grano 600, con una velocidad relativa de 550 RPM durante 20 minutos y con una carga de 937,5 gramos aplicada en dirección normal a la superficie del recubrimiento.Downloads
