Aerosol deposition of hydroxyapatite–chitosan composite coatings on biodegradable magnesium alloy

Bioactive and Antibacterial Coatings Based on Zein/Bioactive Glass Composites by Electrophoretic Deposition

“…Moreover, resorbable biopolymers acting as BG support coatings can accelerate the bonding process between new tissue and the surface of metallic implants by exploiting the polymer gradual degradation. This caters for the growth of new tissue into the implant interface [9]. In addition, the level of ion release from BG particles can be controlled by the degradable biopolymer matrix, [20].…”

“…Different techniques, such as aerosol deposition [9], dip coating [22], and layer by layer (LBL) deposition [23,24] have been used to fabricate inorganic/organic composite coatings on metallic substrates. Electrophoretic deposition (EPD) has recently gained attention as a simple and economic manufacturing process, offering the ability to fabricate uniform coatings on complex-shaped substrates at room temperature [4,8,12,25,26].…”

Biodegradable polymeric coatings for surface modification of magnesium-based biomaterials

“…It was suggested that the nHAp incorporated with PCL composite membranes may serve as an excellent 3-D platform for cell attachment, proliferation, migration and growth in bone tissue. A dense and welladherent HAPechitosan was coated on a magnesium alloy (AZ31) by Hahn et al, (2011). Biocompatibility studies of the hybrid coating showed that the preosteoblast MC3T3-E1 cells were poorly adherent, with a spherical morphology, on the bare alloy; however, on the coated alloy the cells were well attached and spread.…”

Renewable resources in corrosion resistance

“…The derivatives of CHTO such as acetylthiourea CHTO, carboxymethyl CHTO are used as efficient corrosion inhibitors as assessed by PD, EIS, SEM, weight loss measurements, conductometric titrations and other studies (Fekry & Mohamed, 2010;Cheng et al, 2007). Hydroxyapatite-CHTO composite coatings on AZ31 Mg alloy by aerosol deposition produce well adherent, corrosion resistant biocompatible coatings (Hahn et al, 2011) …”
