Titanium (Ti) and its alloys have been widely used as orthopedic implants, because of their favorable mechanical properties, corrosion resistance biocompatibility. Despite significant success in various clinical applications, the probability failure, degradation revision is undesirably high, especially for patients with low bone density, insufficient quantity or osteoporosis, which renders studies on surface modification Ti still active to further improve results. It discerned that physicochemical properties directly influence even control dynamic interaction subsequently determines rejection implants. Therefore, it crucial endow bulk materials specific high bioactivity can be performed by realize osseointegration. This article first reviews characteristics conventional techniques involving mechanical, physical chemical treatments based formation mechanism modified coatings. Such methods are able but surfaces static state cannot respond biological cascades from living cells tissues. Hence, beyond traditional design, responsive avenues then emerging. The stimuli sources functionalization originate environmental triggers physiological triggers. In short, this review surveys recent developments engineering materials, a emphasis advances functionality, provides perspectives improving biocompatibility

Magnesium (Mg) alloys are lightweight materials with excellent mechanical properties, making them attractive for various applications, including aerospace, automotive, and biomedical industries. However, the practical application of Mg is limited due to their high susceptibility corrosion. Plasma electrolytic oxidation (PEO), or micro-arc (MAO), a coating method that boosts alloys' corrosion resistance. despite benefits PEO coatings, they can still exhibit certain limitations, such as failing maintain long-term protection result inherent porosity. To address these challenges, researchers have suggested use inhibitors in combination coatings on alloys. Inhibitors chemical compounds be incorporated into applied post-treatment further boost resistance PEO-coated Corrosion inhibitors, whether organic inorganic, act by forming protective barrier, hindering process, modifying surface properties reduce Containers made materials, polyelectrolyte shells, layered double hydroxides, polymer mesoporous inorganic materials. Encapsulating containers fully compatible matrix substrate promising approach incorporation. Laboratory studies shown results, demonstrating significant mitigation, extending service life alloy components aggressive environments, providing self-healing properties. In general, this review presents available information incorporation which lead improved performance demanding environments.

Hence, compelling advances erosion resistance biocompatibility magnesium its noteworthy. Surface modification may be practical approach it improves compared extensive preparation treated surface progressed bone recovery cell attachment. Coating produced plasma electrolytic oxidation (PEO) seems method order to enhance properties alloys. PEO-formed coatings cannot provide long-term protection physiological due porous nature. Thus, polymer coating is applied on coating, which steadily surface. Polymer improve increase corrosion resistance. In this article, most recent advancements PEO/polymer composite reviewed, such examined.
