“…[ 86 ] In the following, Nikbakht et al confirmed that the coated implant surface would induce toxicity on the surface of the pin due to impeding cells by raising the pH value of the dipping solution. [ 89 ] The adhesion strength of the HA coating layer was reported to be about 10.0 ± 2.8 MPa. [ 90 ] In addition to the above advantages of HA‐coated via the dip coating method on the metallic substrate, Tian et al showed that the adhesion of HA coating with Ag substitution could reduce the Staphylococcus epidermidis and Staphylococcus aureus bacteria on the substrate surface in in vitro study.…”

Science and engineering research studies are currently concentrating on synthesizing, designing, producing, and consuming ecologically benign chemical species to replace harmful chemicals. This is due to the increasing demands of conservation knowledge and strict ecological regulations. Numerous environmentally friendly substitutes produced from natural resources, including biopolymers, plant extracts, chemical pharmaceuticals (drugs), and so on, are now frequently used as inhibitors to replace dangerous corrosion inhibitors. Many compounds have been extensively used. A range of methods, including physisorption, chemisorption, barrier protection, thin-film growth, and electrochemical procedures, will be used to provide corrosion resistance. The various kinds of corrosion inhibitors (CIs), the mechanisms underlying inhibition, and the evaluation procedures have all been covered in-depth. This review provides an overview of the relevant literature in which researchers and scientists used different types of CIs, the effect of CIs on metals, and information about designs and mechanisms used to minimize corrosion in a variety of equipment composed of alloys or metals, along with electrochemical evaluation studies. This review will provide scholars with fresh insights to advance the discipline.

“…Hydroxyapatite (HA) has previously been proven as a corrosion inhibitor because of its buffering effect and reducing potential gradients between anodes and cathodes [ 73 ]. Nikbakht et al added HA nanoparticles to the sol-gel, which helped to optimize the barrier properties of the coating [ 74 ]. The results showed that the addition of 500 mg/L to 1000 mg/L provided desirable corrosion resistance.…”

As the lightest structural materials, magnesium (Mg) alloys play a significant role in vehicle weight reduction, aerospace, military equipment, energy saving, and emission reduction. However, the poor corrosion resistance of Mg alloys has become a bottleneck restricting its wide application. Developing a good surface protective coating can effectively improve the corrosion resistance of Mg alloys. The silane-based sol-gel coating technology has been widely used in the corrosion protection of Mg alloys in recent years due to its advantages of simple process, accessible tailoring of film composition and structure, and excellent corrosion resistance. Whereas the synthesis of sol-gel coatings includes the hydrolysis and dehydration process, which may inherently contain micron or nano defects in the coatings, thereby making it detrimental to the anti-corrosion effect. Therefore, in order to enhance their protection against corrosion, the appropriate modification of sol-gel coatings has become a current research hotspot. This review is based on the modification methods of silane-based sol-gels on the surface of Mg alloys, which are divided into four categories: bare sol-gel, nanoparticles, corrosion inhibitors, and sol-gel-based composite coatings. The modification methods and corrosion protection mechanism are discussed respectively, and the application, development, and research strategies of silane-based sol-gel coatings are included.
