Electrolytic deposition of lithium into calcium phosphate coatings

Dental Materials, 2009
Lithium ions stimulate the Wnt signaling pathway and the authors previously demonstrated that lithium enhances the proliferation of tissue cultured human mesenchymal stem cells. The aim of this study was to prepare and characterize a calcium phosphate/lithium coating by means of electrolytic deposition.

Nanostructured Calcium Phosphate Coating for Stents

Key Engineering Materials, 2007
A nanoporous calcium phosphate (CaP) coating on metallic surfaces is presented. The coating consists of a stack of (a) a TiNbN layer deposited by physical vapor deposition and acting as diffusion barrier against allergenic ions, (b) a SiO2 xerogel layer providing good adhesion properties and designing the nanoporosity of the outer CaP layer (c ...

Electrodeposition of Calcium Phosphate Coatings in Polyvinyl Alcohol

Inorganic Materials: Applied Research, 2022
Brushite coatings were obtained on titanium by the method of electrochemical deposition from Ca(NO3)2/NH4H2PO4 electrolyte at Ca/P = 1.67, pH = 4 and a constant voltage of 15 V or a current density of 20 mA/cm2 for 20 min. In a medium of 0.01 – 0.10 % polyvinyl alcohol at a constant voltage of 15 V, are deposited single-phase brushite or monetite ...

Bioactivity Assessment of Calcium Phosphate Coatings

Key Engineering Materials, 2016
Nowadays, bioactive coatings or modifications on titanium surface have been tested in vitro and in vivo. In this study, two types of calcium phosphate coatings were produced by a chemical deposition method and their bioactivity assay in cell culture medium were investigated.

Calcium phosphate coatings for orthopaedic prosthesis

Surface and Coatings Technology, 1991
Abstract An electrochemical method of deposition which consists of an induction of calcium phosphate precipitation on a titanium cathode is described. Several coatings have been made using this technique and have been characterized by physicochemical methods (infrared spectroscopy, X-ray diffraction, X-ray photoelectron spectroscopy, scanning ...

Calcium Phosphate Coatings for Implant Fixation

2004
It has been predicted that the number of revisions due to mechanical loosening after total hip replacement will increase steadily from year to year due to the increasing number of joint replacements. Unfortunately, results after revision arthroplasty are clearly inferior to those of primary arthroplasty (1).

Bone formation in calcium-phosphate-coated titanium mesh

Biomaterials, 2000
The osteogenic activity of porous titanium fiber mesh and calcium phosphate (Ca-P)-coated titanium fiber mesh loaded with cultured syngeneic osteogenic cells was compared in a syngeneic rat ectopic assay model. In 30 syngeneic rats, (Ca-P)-coated and non-coated porous titanium implants were subcutaneously placed either without or loaded with cultured ...

Electrostatic spray deposition (ESD) of calcium phosphate coatings

Journal of Biomedical Materials Research Part A, 2003
AbstractUsing electrostatic spray deposition (ESD), thin calcium phosphate layers were deposited onto commercially pure cp‐Ti substrates. ESD is a thin‐film technique that enables the deposition of inorganic thin films onto metallic substrates using a simple and cheap experimental set‐up.

[Degradation of electrodeposited calcium phosphate and calcium phosphate-chitosan coatings in vitro].

Zhonghua kou qiang yi xue za zhi = Zhonghua kouqiang yixue zazhi = Chinese journal of stomatology, 2011
To investigate the degradation of electrodeposited calcium phosphate (ECP) coating and calcium phosphate/chitosan (ECPC) coating in vitro.Osteoclasts were isolated from neonatal rabbit long bone cavities and incubated with ECP and ECPC coatings. Calcium ion concentrations in the culture medium were analyzed at 3 days and 6 days.
