4Improvement the Surface Structure of Nickel-Aluminum Bronze (NAB) Alloy Using Al2O3 Nanoparticles and FSP Method


Nickel-Aluminum bronze (NAB) alloy is an alloy of copper base that is used extensively for marine applications such as propellers, because it exhibits excellent corrosion resistance and mechanical properties. For surface hardening and elimination of defects caused by the casting alloy, FSP is applied on NAB. In recent years, this process has been used as an acceptable way to create composite surface layers. In this paper, alumina oxide (Al2O3) nanoparticles are used in order to create a composite layer on the NAB alloy by FSP. Then the hardness and microstructure in three states of casting, FSP, FSP with alumina oxide nanoparticles on the surface are studied and compared. Based on the results, surface composite layer created by FSP has the highest hardness and along with alloy proceeded under FSP process without the presence of nanoparticles in surface has a structure which is fine and free of cast defects.
