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$^{\circ}$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.
