Surface properties of Mg-Gd-Zn-Zr alloy modified by Sn ion implantation

Corrosion Behavior of Fe/Zr Composite Coating on ZK60 Mg Alloy by Ion Implantation and Deposition

“…The potentiodynamic polarization curves were measured at a scan rate of 1 mV•s −1 . The electrochemical parameters of corrosion potential (E corr ), corrosion current density (i corr ) and cathodic slope (β c ) were calculated by CHI-660e software through fitting the potential portion commenced 60 mV from E corr in the cathodic branch [14,25,26]. At least three samples for each group were taken for average.…”

“…to reduce the corrosion rate of Mg-based alloys [8][9][10][11]. Metallic coatings have been proved to exhibit high corrosion resistance, excellent mechanical property, good biocompatibility and favorable electric conductivity, which can simultaneously enhance the corrosion resistance and surface strength without deteriorating the electric conductivity [12][13][14][15][16]. Jin et al [13] deposited Ta-containing coating on the ZK60 Mg alloy surface by reactive magnetron sputtering and the corrosion resistance and biocompatibility were improved by the modified surface composed of Ta 2 O 5 , Ta suboxide and Ta.…”

“…Jin et al [13] deposited Ta-containing coating on the ZK60 Mg alloy surface by reactive magnetron sputtering and the corrosion resistance and biocompatibility were improved by the modified surface composed of Ta 2 O 5 , Ta suboxide and Ta. Ba et al [14] introduced Sn into Mg-Gd-Zn-Zr alloy surface by ion implantation and found that the Sn-implanted Mg alloy exhibited enhanced corrosion resistance and better mechanical properties due to the formation of SnO 2 and MgO on the surface. In addition, composite metallic coatings have been prepared to further modify Mg alloys to obtain desirable corrosion rate.…”

Effect of Nitrogen Ion Implantation Energy on the Mechanical and Chemical Properties of AISI M50 Steel

“…According to former studies, the implantation of nitrogen ions and other kinds of ions into specific steels can improve mechanical and tribological properties, especially hardness, and this has a connection with wear resistance [12][13][14][15]. Moreover, ion implantation is used for different metallic materials and acts beneficially for preventing from another unique form of damage likewise cavitation erosion [16,17].…”

Analysis and comparison of mechanical and chemical properties of protective coatings obtained at different combinations of "target – substrate"

“…Similar difficulties are again associated with insufficient knowledge of the processes occurring during plasma processing, and the ability to control these processes to change the properties of the surface. In addition, scientific studies conducted in [2,3] are aimed at improving the surface properties of steels and alloys, which initially had good strength characteristics. The fact that in [4,5] the effect of the alloying element is mainly studied only on the mechanical or chemical properties of the surface also does not provide complete information about the possibilities of using plasma processing methods to obtain high-quality materials.…”
