Current advancements of hybrid coating on Mg alloys for medical applications

Surface engineering of pure magnesium in medical implant applications

“…The utilization of these polymers serves to diminish the permeation of aqueous solutions onto the surface of magnesium substrates, thereby conferring resistance to solution corrosion. The application of these polymer coating technologies marks significant advancements in the corrosion [ 18 , [231] , [232] , [233] , [234] ]. All components of the Mg-UMAO@PTMC-PDA corrosion-resistant composite coating exert influence on the biodegradation behavior of the Mg substrate.…”

“…Among the various commonly used medical metal implants, Mg and its alloys demonstrate outstanding mechanical characteristics, biodegradability, and the ability for degradation by-products to be metabolically excreted from the body without adverse effects [ [15] , [16] , [17] , [18] ]. Currently, medical Mg implants primarily include Mg alloys such as WE43 [ [19] , [20] , [21] , [22] , [23] , [24] ], AZ31 [ [25] , [26] , [27] , [28] , [29] ], Mg-Ca [ [30] , [31] , [32] , [33] ], and MgZnCa [ [34] , [35] , [36] ].…”

“…Biodegradable metal implants are the new future array towards the field of medicine and biotechnology [1,2]. Pointing out that the goal of the first generation of biomaterials is to obtain a suitable combination of material properties to replace tissues with a general combination, and to show the least toxicity in the host [3,4]. Second-generation biomaterials are characterized by being absorbable by the human body or biologically active; The third generation of biomaterials has both absorbable properties and biological activity, and can help tissues heal themselves once implanted in the body [5].…”
