Characterization and Corrosion Behavior of Hydroxyapatite- Coated Titanium Substrates Prepared Through Laser Induced Liquid Deposition Technique
Titanium and titanium alloys are often used in orthopedic surgery and dentistry because of their especial characteristics such as biocompatibility, mechanical properties, and corrosion resistance. However, their bio- inertness is the most serious drawback for biomedical applications. Therefore, a bioactive coating like hydroxyapatite (HA) is coated on their surface. In this regard, in the prese...
متن کاملDeposition of Nano-Crystalline Fluor-hydroxyapatite Coatings on Titanium Substrates via Sol-Gel Method
In this investigation, fluor-hydroxyapatite (FHA) film was deposited on a titanium substrate by sol-gel method. Triethyl phosphite, ammonium fluoride and calcium nitrate in ethanol solutions were used respectively as P, F and Ca precursors. Typical apatite structures were obtained for all coatings after dipping and subsequent heat treatment at 550, 700 and 800 ºC, the coating layers were ...
متن کاملConductive Polythiophene Nanoparticles Deposition on Transparent PET Substrates: Effect of Modification with Hybrid Organic-inorganic Coating (RESEARCH NOTE)
In this work, Poly(ethyleneterephthalate) (PET) substrate was treated using KOH solution and was modified using hybrid O-I coating containing PCL )polycaprolactone( as organic phase and TEOS )tetraethoxysilane( as inorganic phase. The coating was prepared through a sol-gel process and applied on the surface by dip coater. Then, electrically conducting polythiophene (PTh) nanoparticles were depo...
متن کاملIn Vitro Corrosion and Cytocompatibility Properties of Nano-Whisker Hydroxyapatite Coating on Magnesium Alloy for Bone Tissue Engineering Applications
We report here the successful fabrication of nano-whisker hydroxyapatite (nHA) coatings on Mg alloy by using a simple one-step hydrothermal process in aqueous solution. The nHA coating shows uniform structure and high crystallinity. Results indicate that nHA coating is promising for improving the in vitro corrosion and cytocompatibility properties of Mg-based implants and devices for bone tissu...
متن کاملDeposition of Ultrathin Nano-Hydroxyapatite Films on Laser Micro-Textured Titanium Surfaces to Prepare a Multiscale Surface Topography for Improved Surface Wettability/Energy
The primary aim of this study was to analyse the correlation between topographical features and chemical composition with the changes in wettability and the surface free energy of microstructured titanium (Ti) surfaces. Periodic microscale structures on the surface of Ti substrates were fabricated via direct laser interference patterning (DLIP). Radio-frequency magnetron sputter deposition of u...
