Abstract

Metal foams can be classified as lightweight materials which are low densities, having a unique combination of physical and mechanical properties, energy absorption and good thermal conductivity. 316L Stainless Steel has widely used by researchers as material to fabricate metal foams due to its high-strength-to weight ratio, biocompatibility and corrosion resistance and successfully used in implant applications. The major challenges that need to focused while producing metal foam is the mismatch of the properties between bones and the metallic material. Due to this mechanical mismatch, bone is insufficiently loaded and become stress shielded, which eventually leads to bone resorption. Thus, there are factors need to be considered includes the interconnecting pores that suitable with bone, the pores, shape and density of the implants same with the pores, shape and density of the bone. This research is to fabricate the 316L Stainless Steel (SS316L) foam prepared by Compaction technique and to study and characterize the properties of SS316L foam after sintering process. The SS316L have used as a raw material and Polyethylene glycol (PEG) and Carbamide are used as a binder and space holder respectively. The material was mixed by using ball milling machine to get the homogenous mixture. After that the compaction process was held by using conventional axial pressing. This process is known as powder metallurgy technique. The Properties Characterization was measured by doing density and porosity test, Thermal Gravimetric Analysis (TGA), and Scanning Electron Microscopy (SEM).
