Micro-Arc Oxidation Enhances the Blood Compatibility of Ultrafine-Grained Pure Titanium
Ultrafine-grained pure titanium prepared by equal-channel angular pressing has favorable mechanical performance and does not contain alloy elements that are toxic to the human body. It has potential clinical value in applications such as cardiac valve prostheses, vascular stents, and hip prostheses. To overcome the material's inherent thrombogenicity, surface-coating modification is a crucial p...
متن کاملSynthesis and properties of hydroxyapatite-containing porous titania coating on ultrafine-grained titanium by micro-arc oxidation.
Equal channel angular pressing results in ultrafine-grained (approximately 200-500 nm) Ti with superior mechanical properties without harmful alloying elements, which benefits medical implants. To further improve the bioactivity of Ti surfaces, Ca/P-containing porous titania coatings were prepared on ultrafine-grained and coarse-grained Ti by micro-arc oxidation (MAO). The phase identification,...
متن کاملLanthanum-containing hydroxyapatite coating on ultrafine-grained titanium by micro-arc oxidation: A promising strategy to enhance overall performance of titanium
Titanium is widely used in biomedical materials, particularly in dental implants, because of its excellent biocompatibility and mechanical characteristics. However, titanium implant failures still remain in some cases, varying with implantation sites and patients. Improving its overall performance is a major focus of dental implant research. Equal-channel angular pressing (ECAP) can result in u...
متن کاملn-SiO2 Embedded HA/TiO2 Composite Coatings Deposited on Pure Titanium Substrate by Micro-Arc Oxidation
As orthopaedic and dental metallic implant materials, titanium and titanium alloys are widely used due to their relatively low modulus, good fracture toughness, excellent strenthto-weight ration, and superior biocompatibility and corrosion resistance (Long and Rack, 1998). They have become the first choice above all other candidate metallic implant materials such as Co-Cr-Mo alloys, stainless s...
متن کاملMechanical Strength and Biocompatibility of Ultrafine-Grained Commercial Purity Titanium
The effect of grain refinement of commercial purity titanium by equal channel angular pressing (ECAP) on its mechanical performance and bone tissue regeneration is reported. In vivo studies conducted on New Zealand white rabbits did not show an enhancement of biocompatibility of ECAP-modified titanium found earlier by in vitro testing. However, the observed combination of outstanding mechanical...
