ABSTRACT
The erosion behavior of alumina-reinforced ZA-27 alloy composites fabricated by stir casting technique is studied by means of erosive wear-test rig. In this investigation, the influence of independent parameters such as impact velocity, filler content, erodent temperature, impingement angle, erodent size on erosive wear behavior of composites was studied. A finite element (FE) model (ANSYS/AUTODYN) of erosive wear was established for damage assessment and validated by a well-designed set of design of experiment (DoE) technique. It is observed that there is a good agreement between the computational and experimental results, and that the proposed simulation model is very useful for the evaluation of damage mechanisms. The results obtained in this work enable alumina-reinforced ZA-27 alloy composites to exhibit better wear resistance as compared with unfilled ZA-27 alloy composite.
