Formation of metal coatings on magnesium using a galvanic replacement reaction in ionic liquid

Abstract

Surface coatings of Cu, Ni, Zn, and Ti on magnesium are deposited using a galvanic replacement reaction in butylmethylpyrrolidiniumdicyanamide ionic liquid. The coated samples show improved corrosion resistance compared to bare Mg.

Deposition of Gold Nanoparticles via Galvanic Replacement in DMSO and Their Influence on Formation of Silicon Nanostructures

“…is complicates the controlled formation of MNPs, as a necessary condition for the surface modification. As it was shown in our previous works [31][32][33][34], GR in the organic solvent medium overcomes these disadvantages of aqueous solutions. In addition, organic solvents often play a role of a surfactant due to their electron-donor properties, affecting the geometry of nanoparticles and their size distribution.…”

Synthesis and characterization of a phytic acid/mesoporous 45S5 bioglass composite coating on a magnesium alloy and degradation behavior

“…Besides, magnesium is the fourth most abundant cation in human beings, which has a fundamental inuence on cellular and enzymatic reactions. [2][3][4][5][6][7][8] However, the fast degradation rate of magnesium alloys would lead to an inhomogeneous localized degradation and nally resulted in a quick decline of their mechanical strength and a high level of local pH values surrounding the human tissues, which are undesired for the healing of the implant area. [9][10][11] Therefore, some surface treatments have been developed to control the degradation rate of magnesium alloys, such as chemical conversion layers, micro arc oxidation, sol-gel coatings and immersion treatment.…”
