“…Figure 4, Mg(OH) 2 and MgF 2 are not detected by the XRD examination, which indicates that these two phases may be amorphous. This agrees well with the results obtained by Pereda et al [27] . Moreover, as KF concentration increases from 0.1 M to 0.5 M, the diffraction peaks of KMgF 3 broaden and weaken, meaning a decrease in the crystalline of KMgF 3 [34] .…”

“…However, as Pereda et al [26,27] pointed out, the higher concentration of KF solution did not bring the better corrosion resistant FCF coating and much more precipitate of KMgF 3 . So far, this is still an unknown fact that needs to clarify.…”

“…Pereda et al [26,27] firstly carried out the potentiostatic deposition of FCF on pure Mg in KF solution. They found the effect of KF concentration on the corrosion resistance of FCF coated pure Mg.…”

“…The elemental composition of the corresponding surface indicates that the polarized surface is composed of Mg, F, O and K, indicating K + ions have participated in the formation of the conversion film in the final of the current decay. According to the XRD database and the Refs [27] and [30] , the crystallized particles can be identified as KMgF 3 . Figure 5g and 5h reveals the surface morphologies of AZ31 Mg alloy polarized for 10 s and 100 s in 0.5 M KF solution, respectively.…”

The dependence of coating process and properties of the fluoride conversion film on AZ31 Mg alloy on the concentration of deaerated KF solutions was studied by anodic potentiostatic deposition, scanning electron microscopy (SEM), energy dispersive X-ray spectroscopy (EDS), X-ray diffraction (XRD), X-ray photoelectron spectroscopy (XPS), and electrochemical impedance spectroscopy (EIS). The results show that the film deposited in 0.05 M KF solution is a monolayer consisting of amorphous Mg(OH) 2 and MgF 2 , while amorphous Mg(OH) 2 and MgF 2 and crystallized KMgF 3 as a double layer formed in 0.1 M~0.5 M KF solutions. The composition of inner layer is same as that of the monolayer, while the outer layer is composed of Mg(OH) 2 and MgF 2 and KMgF 3 . Continually increasing KF concentration reduces the content of KMgF 3 in the outer layer, shortens the coating duration, and reduces the film thickness. The corrosion resistance of FCF coatings is closely correlated with the content of KMgF 3 and the film thickness.

“…[4][5][6][7] However, the use of Mg as biomaterial is seriously limited due to its fast dissolution rate in the physiological environment. [8][9][10][11][12][13][14][15] Consequently, different alloying elements have been introduced for specific reasons and, in most of the cases, corrosion resistance has been improved.

Comparison of the Corrosion Behavior of Coated and Uncoated Magnesium Alloys in an In Vitro Corrosion Environment

et al. 2011

View full text Add to dashboard Cite

The in vitro degradation of magnesium alloys with various alloying elements, the effect of coatings, and the impact of an altered experimental environment are investigated. LANd442 and Nd2 alloys are subjected to a continuously moving environment during an immersion test allowing flowing SBF. Applying an MgF2 coating to the alloys increases the corrosion resistance of LANd442 but has no effect on the corrosion rate of Nd2 within the period of investigation. It leads to a more‐even degradation with less pitting corrosion in the early stages of corrosion. A bioglass coating on Nd2 increases the corrosion rate. The mass loss, volume loss, and loss in maximum force all show the same trends as the specimens degrade over time.
