| Summary: | Metal foams are a special class of porous materials with novel physical, mechanical, thermal, electrical and acoustic properties. Nowadays, 316L stainless steel (SS316L) foam is considered as one of the attractive metallic materials for biomedical applications due to its excellent mechanical properties, biocompatibility, and corrosion resistance. In this study, SS316L has been used to produce metal foams using the slurry method. The compositions of the SS316L metal powder were 40 wt% and 60 wt%, PEG (3 wt%), CMC (3 wt%) with the remainder distilled water. Polyethylene glycol (PEG) and methylcellulose (CMC) were used as a binder. The raw materials were mixed using a ball milling machine. After that, the polyurethane (PU) foams were immersed in the mixture then dried in the oven for 24 hours. Then, the samples were sintered in a box furnace at 1300oC. In order to characterize the samples, several tests were conducted such as x-ray diffraction (XRD), energy diffraction x-ray (EDX), and morphological analysis (optical microscopy and scanning electron microscopy (SEM)). The most suitable composition of SS316L is 60 wt% with a sintering temperature of 1300°C which resulted in large-pored metal foam. The SS316L metal foams were successfully produced using the slurry method. However, the quality of the SS316L metal foam must be improved because it had too low a strength to undergo mechanical testing. |
