Fabrication of Zinc-Based Fe + Ag + Mg Nano-Particles-Reinforced Biodegradable Composite
摘要
The Zinc has good properties in terms of bio-degradation and biocompatibility. Zinc was found to exhibit near-ideal corrosion rate in the biological environment. Keeping in view, biodegradable composite was developed by reinforcement of Fe, Ag and Mg powders through a stream of argon gas into the molten zinc via ultrasonic vibration-assisted stir casting. The mechanical properties of the composites were studied through various tests. The mechanical characteristics of the developed zinc reinforced with Ag, Fe, and Mg particles match the general requirements for a bio-absorbable material, according to test results, and it could be used as a substitute material for medical implants. The effect of parameters on MRR (mg/min) and TWR (mg/min) was examined experimentally during µ-drilling of hybridized Zn/(Fe + Ag + Mg) biodegradable composite to fabricate stents mini-tube on first drill EDM. The appearance of the drilled holes was also depicted in SEM images.
