“…The most common ways to improve the electrochemical properties of bioresorbable magnesium alloys are mechanical treatment by plastic deformation (extrusion, pressing, twisting, etc.) [ 5 , 12 , 13 , 14 , 15 , 16 ], alloying [ 16 , 17 , 18 , 19 , 20 , 21 , 22 , 23 ], and formation of protective bioactive coatings. Several methods are known for applying such protective layers, for example, sol-gel technology [ 24 , 25 ], layer-by-layer deposition (polyelectrolyte multilayers) [ 26 , 27 ], hydrothermal deposition [ 28 , 29 ], plasma spraying [ 30 , 31 ], laser cladding [ 32 ], electrochemical [ 33 , 34 , 35 , 36 ] and chemical [ 37 , 38 , 39 ] deposition, cold sprayed deposition, etc.…”

The increase of corrosion resistance of magnesium and its alloys by forming the smart self-healing hybrid coatings was achieved in this work in two steps. In the first step, using the plasma electrolytic oxidation (PEO) treatment, a ceramic-like bioactive coating was synthesized on the surface of biodegradable MA8 magnesium alloy. During the second step, the formed porous PEO layer was impregnated with a corrosion inhibitor 8-hydroxyquinoline (8-HQ) and bioresorbable polymer polycaprolactone (PCL) in different variations to enhance the protective properties of the coating. The composition, anticorrosion, and antifriction properties of the formed coatings were studied. 8-HQ allows controlling the rate of material degradation due to the self-healing effect of the smart coating. PCL treatment of the inhibitor-containing layer significantly improves the corrosion and wear resistance and retains an inhibitor in the pores of the PEO layer. It was revealed that the corrosion inhibitor incorporation method (including the number of steps, impregnation, and the type of solvent) significantly matters to the self-healing mechanism. The hybrid coatings obtained by a 1-step treatment in a dichloromethane solution containing 6 wt.% polycaprolactone and 15 g/L of 8-HQ are characterized by the best corrosion resistance. This coating demonstrates the lowest value of corrosion current density (3.02 × 10−7 A cm−2). The formation of the hybrid coating results in the corrosion rate decrease by 18 times (0.007 mm year−1) as compared to the blank PEO layer (0.128 mm year−1). An inhibitor efficiency was established to be 83.9%. The mechanism of corrosion protection of Mg alloy via smart hybrid coating was revealed.

“…Magnesium alloys have become the first choice for biodegradable metal materials in the field of medical implant materials due to their unique biodegradability and biocompatibility, as well as mechanical properties very similar to those of human bones. [8][9][10][11][12] Although magnesium alloy has many advantages, its corrosion rate is not consistent with the healing rate of human bone. In addition, the mechanical properties of magnesium alloys need to be improved, which also hinders their wide application.…”

Magnesium alloy shows promise of becoming a new generation of degradable biomaterials because of its good biocompatibility and mechanical properties. This paper details the preparation of magnesium alloy by adding calcium and zinc elements to pure magnesium at a specific ratio and strengthened by solid solution treatment and extrusion. The magnesium alloy is subjected to micro-motion wear testing, in vitro degradation product analysis, and in vitro biocompatibility testing and demonstrates excellent performance. The study demonstrates that the prepared Mg-2.0Zn-1.6Ca alloy friction ring has an elliptical shape with a low friction coefficient, which notably enhances the wear resistance of the material. Furthermore, the corrosion of magnesium alloy products in simulated body fluids does not adversely affect the human body. This is because the surface of the magnesium alloy favors cell growth and has excellent antimicrobial properties. The purpose of this paper is to enhance the preparation, surface friction properties, and biocompatibility of magnesium alloys and to provide theoretical and practical guidance for the preparation, processing, and application of high-performance medical magnesium alloys.
