“…Immersion times differ from different bacteria reproductive cycles, antibacterial ingredients, antibacterial ingredient concentrations, and the releasing rates. A novel gentamicin-loaded HA coating was introduced by Ji et al [19,21] by the Layer-by-Layer (LbL) assemble method. The antibacterial coating possessed effective antibacterial properties due to the local high GS concentration.…”

“…Many antibacterial ingredients were adopted to enhance the antibacterial properties of the coatings on magnesium and its alloys. Most of the research studies were carried out by adding antibiotics [21][22][23] or antibacterial metallic elements (silver, copper, zinc, etc.) [24][25][26] into polymer coatings [27][28][29][30] or calcium phosphates (Cap) coatings [31,32].…”

As a revolutionary implant material, magnesium and its alloys have many exciting performances, such as biodegradability, mechanical compatibility, and excellent biosecurity. However, the rapid and uncontrollable degradation rate of magnesium greatly hampers its clinical use. Many efforts have been taken to enhance the corrosion resistance of magnesium. However, it must be noted that improving the corrosion resistance of magnesium will lead to the compromise of its antibacterial abilities, which are attribute and proportional to the alkaline pH during its degradation. Providing antibacterial functionalized coating is one of the best methods for balancing the degradation rate and the antibacterial ability of magnesium. Antibacterial functionalized magnesium is especially well-suited for patients with diabetes and infected wounds. Considering the extremely complex biological environment in the human body and the demands of enhancing corrosion resistance, biocompatibility, osteogenesis, and antibacterial ability, composite coatings with combined properties of different materials may be promising. The aim of this review isto collect and compare recent studies on antibacterial functionalized coatings on magnesium and its alloys. The clinical applications of antibacterial functionalized coatings and their material characteristics, antibacterial abilities, in vitro cytocompatibility, and corrosion resistance are also discussed in detail.

“…Magnesium alloys as light structural metal material are charmful for manufacturing industry, especially in transportation, electronics, aerospace field where a lighter engineering system are key to reduce energy consumption. However, Mg alloys is plagued with the poor corrosion resistance due to the active chemical properties compared to other engineering metal, such as steel and aluminum alloys [1][2][3][4]. Over the past decades, nanometer amorphous film is very common as passive layer in the areas as microelectronics, optics and solar cells devices [5][6][7], which would impart remarkable resistance to general corrosion.…”

A comprehensive investigation of nano crystallized GaN film synthesized on AZ31 magnesium alloy substrate using atomic layer deposition (ALD) is presented in this paper. The microstructure and mechanical analysis indicate the nano crystallized film is homogeneous, well-adhesive to Mg alloy substrate. The corrosion experimental results demonstrate that the nanometer crystallized film turns Mg alloy corrosion process from longitudinal/non-uniform to horizontal/uniform corrosion, which is deduced from the facts that a great but less fluctuation surface potential mapping, a smaller ∆Erev, corr and a more uniformed corroded morphology. A higher Ecorr , a smaller icorr and a higher Z also mean the film can yield a prominent amelioration in the Mg alloy corrosion resistance. The work proposes that a uniform coverage even in a nano-magnitude and crystallized form could make corrosion more uniform and later.

“…The rate of coatings dissolution and their biological properties depend on the substances that the coatings are consisted of. The most common biocoatings are based on the calcium orthophosphates such as hydroxyapatite (HA) [22,25,27,40] and tricalcium phosphate (TCP) [34] or include their combinations. Hydroxyapatite has the lowest dissolution rate in body fluids.…”

Comparative Study of the Structure, Properties, and Corrosion Behavior of Sr-Containing Biocoatings on Mg0.8Ca

A comparative analysis of the structure, properties and the corrosion behavior of the micro-arc coatings based on Sr-substituted hydroxyapatite (Sr-HA) and Sr-substituted tricalcium phosphate (Sr-TCP) deposited on Mg0.8Ca alloy substrates was performed. The current density during the formation of the Sr-HA coatings was higher than that for the Sr-TCP coatings. As a result, the Sr-HA coatings were thicker and had a greater surface roughness Ra than the Sr-TCP coatings. In addition, pore sizes of the Sr-HA were almost two times larger. The ratio (Ca + Sr + Mg)/P were equal 1.64 and 1.47 for Sr-HA and Sr-TCP coatings, respectively. Thus, it can be assumed that the composition of Sr-HA and Sr-TCP coatings was predominantly presented by (Sr,Mg)-substituted hydroxyapatite and (Sr,Mg)-substituted tricalcium phosphate. However, the average content of Sr was approximately the same for both types of the coatings and was equal to 1.8 at.%. The Sr-HA coatings were less soluble and had higher corrosion resistance than the Sr-TCP coatings. Cytotoxic tests in vitro demonstrated a higher cell viability after cultivation with extracts of the Sr-HA coatings.
