Suspension Plasma Sprayed Titanium Oxide and Hydroxyapatite Coatings
The paper aims at development of TiO2, Ca5(PO4)3OH (hydroxyapatite, HA) and their multilayer coatings onto stainless steel, titanium and aluminum substrate using suspension plasma spraying. The total thickness of the coatings was in the range 10 to 150 μm. The suspension on the base of distilled water, ethanol and their mixtures was formulated with the use of fine commercial TiO2 pigment crysta...
متن کاملBone Tissue Response to Plasma Sprayed Hydroxyapatite Coatings: An In Vivo Study on Rabbit Femoral Condyles
In this study, hydroxyapatite was coated on titanium substrates by plasma spraying process. A well-known porous and lamellar microstructure was found in the lateral a...
متن کاملEarly bone apposition in vivo on plasma-sprayed and electrochemically deposited hydroxyapatite coatings on titanium alloy.
Three different implants, bare Ti-6Al-4V alloy, Ti-6Al-4V alloy coated with plasma-sprayed hydroxyapatite (PSHA), and Ti-6Al-4V alloy coated with electrochemically deposited hydroxyapatite (EDHA), were implanted into canine trabecular bone for 6 h, 7, and 14 days, respectively. Environmental scanning electron microscopy study showed that PSHA coatings had higher bone apposition ratios than thos...
متن کاملCharacterization of functionally graded hydroxyapatite/titanium composite coatings plasma-sprayed on Ti alloys.
Bioceramic coatings like hydroxyapatite (HA) have shown promising bioactive properties in load-bearing implant applications. The aim of this work is to deposit functionally graded HA/Ti layers consisting of an underlying Ti bond coat, the alternating layer, and an HA top-layer on Ti6Al4V substrates using plasma spray to improve the coating-substrate interface properties. The alternating layers ...
متن کاملFunctional Coatings or Films for Hard-Tissue Applications
Metallic biomaterials like stainless steel, Co-based alloy, Ti and its alloys are widely used as artificial hip joints, bone plates and dental implants due to their excellent mechanical properties and endurance. However, there are some surface-originated problems associated with the metallic implants: corrosion and wear in biological environments resulting in ions release and formation of wear ...
