Abstract
Recently, there has been a notable rise in the use of Hydroxyapatite (HA) coatings in medical implants, especially those composed of magnesium alloys. This study involves immersing Mg alloys in a HA and MoS2 solution for varying durations. Results indicated that HA+MoS2 coatings have greater polarization resistance than HA coating, with the 120-minute MoS2-modified coating achieving maximum corrosion resistance (30163 ohm.cm²) in a 3.5 wt% NaCl solution. Characterization techniques confirmed the successful integration of HA and MoS2, while the coatings also exhibited strong antibacterial activity. Additionally after seven days of submerging in SBF, the HA+MoS2(120 min) coating demonstrated the highest bio-corrosion resistance, measuring around 10848 ohm.cm2.
期刊介绍：
Corrosion occurrence and its practical control encompass a vast array of scientific knowledge. Corrosion Science endeavors to serve as the conduit for the exchange of ideas, developments, and research across all facets of this field, encompassing both metallic and non-metallic corrosion. The scope of this international journal is broad and inclusive. Published papers span from highly theoretical inquiries to essentially practical applications, covering diverse areas such as high-temperature oxidation, passivity, anodic oxidation, biochemical corrosion, stress corrosion cracking, and corrosion control mechanisms and methodologies.
This journal publishes original papers and critical reviews across the spectrum of pure and applied corrosion, material degradation, and surface science and engineering. It serves as a crucial link connecting metallurgists, materials scientists, and researchers investigating corrosion and degradation phenomena. Join us in advancing knowledge and understanding in the vital field of corrosion science.
