Resumen
En este trabajo se evalúa la resistencia al desgaste de dos tipos de aleaciones FeMnAl (AF1 y AF2) con y sin tratamiento térmico (TT) y se compara con el acero inoxidable ASTM A240 (AI), a través del ensayo pin-on-disk. El ensayo tribológico se llevó a cabo utilizando pin de alúmina de diámetro de 6 mm, a una carga normal de 10 N y 300 m de recorrido; la velocidad del ensayo fue de 120 rpm y se evaluaron dos temperaturas: temperatura ambiente y 300°C. Se observó que las aleaciones fermanal ricas en manganeso (AF2) presentan la mayor resistencia al desgaste a temperatura ambiente, y a altas temperaturas es más resistente el AI, seguido por AF1. Mediante Microscopía Electrónica de Barrido se identificaron micro-arado, adhesión y oxidación como los mecanismos de desgaste predominantes.
Descriptores: Acero inoxidable; fermanal; coeficiente de fricción; desgaste.
Abstract
In this paper, we evaluate the wear resistance of two types of alloys fermanal (AF1 and AF2) with and without thermal treatment (TT) and compared with ASTM A240 stainless steel (AI) through the testing pin-on-disk. The tribological tests were carried out using a alumina pin diameter of 6 mm, a normal load of 10 N and 300 m of travel, the test speed was 120 rpm and were evaluated at two temperatures: room temperature and 300°C. It was observed that fermanal alloys with high content of manganese (AF2) have the highest wear resistance at room temperature and at high temperatures is resistant the AI, followed by fermanal AF1. Through Scanning electron microscopy is found micro-plowing, adhesion and oxidation as the dominant wear mechanisms.
Keywords: Stainless steel; fermanal; coefficient of friction; wear.
