Abstract

This work includes a single-track study of Alumina (Al₂O₃)-Electrolytic Iron Powder (EIP) composites in different weight percentage compositions using the selective laser melting (SLM) process. This experimental study aims to find the feasibility of Alumina and EIP composites at different wt.% composition at fixed process parameters. It specifically involves powder preparation through ball milling, tracking the morphology, element mapping of the layer at different Alumina compositions, microhardness, and scratch test results, which are discussed at the end. The outcomes relate the microhardness with different weight compositions of Alumina quantitatively. The element mapping confirmed the presence of composite powder and showed the separate substrate at the interface. A scratch test was also performed, and it was found that the single layer resistance against abrasion and scratches at different percentage compositions of Alumina when subjected to ramp loading.
