Abstract

The interpenetrating (HA+β-TCP)/Mg-3Zn composites were fabricated by infiltrating Mg-3Zn alloy into porous HA+β-TCP with different HA contents using suction casting technique, and the microstructure, mechanical properties and corrosion behavior of the composites were evaluated. Results show that the molten Mg-3Zn alloy not only infiltrates into the pores but also infiltrates into the struts of the porous HA+β-TCP scaffold to form a compact composite. The Mg-3Zn alloy is in close contact with the HA+β-TCP scaffold, and no reaction layer can be found. The compressive strength of the (HA+β-TCP)/Mg-3Zn composites with different HA content is 115~196 MPa, which is about 350-fold higher than that of the original porous HA+β-TCP scaffold and accounts for 44%~75% of the strength of the Mg-3Zn bulk alloy. The corrosion resistance of the composites is better than that of the Mg-3Zn bulk alloy, and the mechanical properties and corrosion behavior of the composites can be controlled by the HA/β-TCP ratio. © 2018, Science Press.

The co-continuous (HA+β-TCP)/Zn–3Sn composite was fabricated via vacuum casting-infiltration method. The microstructure, mechanical properties, corrosion behaviors, and hemolysis ratio of the composite were studied by scanning electron microscope, X-ray diffractometer, mechanical testing, electrochemical test, immersion test, and ultraviolet spectrophotometry. The results indicate that Zn–3Sn alloy infiltrated into porous HA+β-TCP scaffold, which resulted in the formation of a compact (HA+β-TCP)/Zn–3Sn co-continuous composite, without any reaction layer between the Zn–3Sn alloy and the HA+β-TCP scaffold. The compressive strength of the composite was equal to about 3/4 that of Zn–3Sn alloy bulk. The corrosion rate of composite in simulated body fluid solution was slightly higher than that of Zn–3Sn alloy bulk. The main corrosion product on the composite surface was Zn(OH)2. The hemolysis rate of the composite was lower than that of Zn–3Sn alloy bulk and exhibited superior blood compatibility.
