SS 316L/HA composite via powder injection moulding: Mechanical and physical properties
The bio-active and biological affinity with bony tissue effect of hydroxyapatite (HA) marks as a chosen material for implants application. Uniting HA which has low mechanical properties that limit its application with a higher mechanical property of metallic biomaterial 316L stainless steel (316L) t...

| description |
The bio-active and biological affinity with bony tissue effect of hydroxyapatite (HA) marks as a chosen material for implants application. Uniting HA which has low mechanical properties that limit its application with a higher mechanical property of metallic biomaterial 316L stainless steel (316L) to form a biocomposite have been a solution to produce acceptable mechanical properties for human implant. The 316L/HA biocomposite would have attribute vital to current implant materials, like a low Young’s modulus, high compatibility, and bio-inertness. This study concentrates on investigating the mechanical and physical properties of the 316L/HA biocomposite fabricated by metal injection moulding. The synthesis HA was produced from calcium-Phosphate. While, Polypropylene (PP), Stearin Acid (SA) and primary binder, Paraffin wax (PW) used as a binder system. Different weight of HA (0, 5, 10 and 15 wt. %) ratios to SS 316L/HA were prepared. All samples were sintered at 1350 ºC for 2 hours soaking time. The result shows that 10 wt.% HA biocomposite and above have higher porosity and low mechanical strength.
