The aim of this study was to address insufficient load-bearing capacity, and lack antibacterial properties porous Ti6Al4V (TC4) alloy, TC4-5Cu alloy with designed honeycomb structure were prepared by additive manufacturing technology. effects wall thickness (100–300 μm) on the microstructure, mechanical properties, antimicrobial osseointegration ability alloys systematically investigated. Results indicated that composed α'/α, β Ti2Cu phases. With increase thickness, elastic modulus, yield...

Abstract The service life as hard tissue implantation for clinical application needs compatible mechanical properties, e.g. strength, modulus, etc, and certain self-healing in case of internal infection. Therefore, sake improving the properties Ti-Cu alloy, microstructure, corrosion resistance antibacterial Ti- x Cu alloy ( = 2, 5, 7 10 wt.%) prepared by Ar-arc melting followed heat treatment were studied. results show that was mainly composed α -Ti matrix precipitated Ti 2 phase. element...

The potential biomedical application near β-type Ti-35Nb-7Zr alloy with different CPP ceramic additions were evaluated in vitro using electrochemical method and osteoblasts co-cultured. A small amount addition of calcium pyrophosphate (CPP) induced the formation oxide film on surface composites that can withstand passive layer breakdown onset localized forms corrosion. But occurred as exceeded 20 wt%. Ti-35Nb-7Zr-10CPP exhibits a wide range polarization curve gets higher for inducing growth...

The Ti-6Al-4V (TC4) alloy wheel hub has exhibited some defects that affect the properties during vertical centrifugal casting process. Therefore, analysis of solidification process would contribute to solving above-mentioned problems. In this study, an orthogonal experimental design was employed optimize parameters (rotational speed, mold preheating temperature, and pouring temperature) method. effects on velocity field, temperature total shrinkage porosity were explored, microstructure...
