Morphological analysis of SS316L foam produced by using slurry method
Metal foams had been developed years ago by researchers. There were various methods used to produce metal foam such as slurry, compaction, gas entrapment technique and casting methods. In this study, slurry method used to produce SS3 16L foam with powder compositions 50wt%, 55wt% and 60wt%. Polyethy...

| Summary: | Metal foams had been developed years ago by researchers. There were various methods used to produce metal foam such
as slurry, compaction, gas entrapment technique and casting methods. In this study, slurry method used to produce
SS3 16L foam with powder compositions 50wt%, 55wt% and 60wt%. Polyethylene Glycol (PEG) and Carboxyk, Methyl
Cellulose (CMC) were used as binder which was mixed with SS3 16L powder and distilled water. Polyurethane (PU) foams
were impregnated with slurry and squeezed as ensure uniform coverage of every pore and struts of the PU foams. The coated PU foams were then dried in the oven for 24 hours at 30°C, followed by sintering process in the vacuum furnace at three different temperatures of 1200°C, 1250°C and 1300°C. Elements of Oxygen, Aluminium, Calcium, Silicon, Chromium,
Nickel, Ferrous and Molybdenum were identified in the SS316L foams, as analysed by SEM-EDX analyses. |
