“…Extending on this aspect provides a comprehensive understanding of the challenges associated with magnesium implants. Magnesium alloys are prone to abrasive wear, especially in scenarios involving contact with hard and abrasive surfaces [164]. The inherent softness of magnesium can result in accelerated material loss, leading to concerns about the long-term durability of implants.…”

Magnesium has been a focal point of significant exploration in the biomedical engineering domain for many years due to its exceptional attributes, encompassing impressive specific strength, low density, excellent damping abilities, biodegradability, and the sought-after quality of biocompatibility. The primary drawback associated with magnesium-based implants is their susceptibility to corrosion and wear in physiological environments, which represents a significant limitation. Research findings have established that plasma electrolytic oxidation (PEO) induces substantial modifications in the surface characteristics and corrosion behavior of magnesium and its alloy counterparts. By subjecting the surface to high voltages, a porous ceramic coating is formed, resulting in not only altered surface properties and corrosion resistance, but also enhanced wear resistance. However, a drawback of the PEO process is that excessive pore formation and porosity within the shell could potentially undermine the coating’s corrosion and wear resistances. Altering the electrolyte conditions by introducing micro- and nano-particles can serve as a valuable approach to decrease coating porosity and enhance their ultimate characteristics. This paper evaluates the particle adhesion, composition, corrosion, and wear performances of particle-incorporated coatings applied to magnesium alloys through the PEO method.

“…Several studies have analyzed different PVD techniques in order to tackle the problems encountered when coating Mg alloys: DC magnetron sputtering [12], radio frequency magnetron sputtering [36], cathodic arc physical vapor deposition [37], or High-Power Impulse Magnetron Sputtering (HiPIMS) [38,39]. Among them, HiPIMS technology has shown the best performance in terms of mechanical properties and corrosion resistance when depositing ceramic coatings on Mg alloys.…”

In this work, hydrogenated and hydrogen-free Diamond-Like Carbon (DLC) coatings were deposited into ZK60 magnesium alloy using the promising coating method High-Power Impulse Magnetron Sputtering (HiPIMS). CrC and WC were used as interlayers of the thin films, and their influence was studied. The structure and composition of the coatings were characterized using scanning electron microscopy (SEM), energy-dispersive X-ray spectroscopy (EDS), and Raman spectroscopy. Tribological tests, scratch tests, and nanoindentation were performed to obtain information about the mechanical and tribological properties of the coatings. Finally, immersion and electrochemical tests were performed to evaluate the corrosion behavior of the samples. The results showed a homogeneous layer with improved wear resistance, toughness, and hardness in addition to good adhesion to the substrate of the ZK60 magnesium alloy. The hydrogenated DLC coating showed better results that the hydrogen-free thin layer, and relevant differences were observed depending on the interlayer. In this work, the improvement in the tribological and corrosive properties of Mg alloys was studied by using thin layers of DLC and different intermediate layers, achieving similar or even better wear and adhesion values than with thicker layers.

“…Generally, coated materials has good adhesion strength and improved surface & morphological properties while comparing to uncoated materials. Thin hard coatings were playing important role in industrial applications especially production of mechanical tools and components, due to excellent surface hardness and wear resistive properties [1][2][3][4][5][6][7].…”
