ABSTRACT: In this work, erosion tests were performed to study the behavior of an aluminium alloy known as
AISI 6061-T6 against the impact action of aluminium oxide abrasive particles. This material was
selected because of its high ductility and tenacity. An erosion rig based on that in ASTM G76-95
was used to conduct the tests. The alumina particles had a particle size between 300 and 400 μm.
Four incident angles, 30°, 45°, 60° and 90° were used to conduct the erosion tests. The particle velocity
and the abrasive flow rate were 24 ± 2 m/s and 63 ± 0.5 g/min. The room temperature was
between 35°C and 40°C. Chemical analysis of the material and abrasive particles were obtained
using energy dispersive X-ray analysis (EDS). SEM images were employed to identify the wear
mechanisms, which were characterized by high plastic deformation. The erosion rates were obtained
and the results indicated that the maximum erosion damage was achieved at 30° reducing
progressively at normal incidence.
