“…The higher value of activation energy for crystallization in al-ni-y-Ce alloys, compared with other al-based amorphous alloys, for instance, al 83 ni 10 Si 2 Ce 5 , al 87 ni 5 Co 2 nd 6 and al 85 ni 10 Ce 5 amorphous alloys, also implies the much higher thermal stability of MEaa ribbons [27]. in general, wear resistance is closely allied to the hardness of the metal material [28].

EffEcts of Yttrium (Y) substitution bY cErium (ce) on microstructurE and corrosion bEhavior of nEar-Equiatomic alniY mEdium-EntropY amorphous alloY ribbonsThrough partially replacing y element, Ce was added into near-equiatomic alniy medium-entropy amorphous alloy (denoted as MEaa) ribbons by the melt spinning process in this study. The differences of microstructure, thermal stability, hardness and corrosion resistance of al 33.3 ni 33.3 y 33.4-x Ce x (x = 0, 2, 5, 8, 13) alloy ribbons were investigated by X-ray diffraction (XRD), scanning electron microscope (SEM), differential scanning calorimeter (DSC) and Vickers-type hardness tester. The anti-corrosion performance in 3.5 wt.% naCl solution of alloy ribbons was investigated elaborately through the general potentiodynamic polarization curves (Tafel) and electrochemical impedance spectroscopy (EiS). Results suggested that all ribbon samples could remain amorphous structure and the hardness are all above 510 hV 0.1 . With the increase of Ce content, the thermal stability begins to be gradually lower. however, according to the analysis of crystallization kinetics, all types of MEaa ribbons presents the relatively prominent thermal stability compared with traditional al-based amorphous alloys. The corrosion current density raises firstly, then shows a decreasing trend, and has a slight increase at last. Therefore, appropriate content of Ce element can improve the corrosion protection performance of alloy ribbons and the 5 at.% Ce MEaa ribbons exhibited the excellent corrosion resistance in this study.

“…The partial substitution of Fe by mixed rare earth reduced the amorphous formation ability of the coating, and the amorphous content was reduced from 74.9% to 64.3%. Zhou et al 63 prepared Albased amorphous coatings by changing the powder ratio and found that when the content of Ni or Ti was low, there were more intermetallic compounds such as a-Al, Al 3 Ni and Al 3 Ti, and the amorphous content was low. With the increase of Ni or Ti content, the amorphous content first increased and then decreased, and the crystalline phase decreased significantly.…”

Compared with crystal alloy, amorphous alloy features atomic arrangement of long-range disorder and near-range order; it has no crystal boundary, dislocation and other defects that can easily promote corrosion initiation and development. With good mechanical properties, wear resistance and corrosion resistance properties, today amorphous alloys have become a research hotspot worldwide. However, the amorphous formation ability is limited, which restricts large-scale preparation, popularization and application of three-dimensional block materials. Due to the technical characteristics of rapid solidification, laser cladding technology and spraying technology are beneficial to the efficient preparation and transformation of amorphous alloy in the form of coating materials. According to the current research progress of amorphous and nanocrystalline composite coatings, this article introduces the typical amorphous and nanocrystalline composite coating alloy systems, summarizes the research progress of preparing amorphous and nanocrystalline composite coatings and expounds the research situation of the main mechanical properties, wear resistance and corrosion resistance of amorphous and nanocrystalline composite coatings. Finally, the application scope of amorphous and nanocrystalline composite coatings is reviewed, and the current problems and future development trends in the study of amorphous and nanocrystalline composite coating are indicated.Zhibin Zhang and Jiachi Yuan have contributed equally to this work.

“…In recent years, the binary and ternary metallic glasses of Al-Ni-Ti systems have been intensively studied experimentally in terms of their structures, properties and metallic glass formation [15,16]. For instance, Howie explored metallic glass formation in Al-Ni-Ti and demonstrated that fwhm and corrosion resistance are correlated and that a large fwhm, attributed to a glassy phase, is necessary for the highest corrosion resistance [15].…”

An empirical potential under the formalism of second-moment approximation of tight-binding potential is constructed for an Al-Ni-Ti ternary system and proven reliable in reproducing the physical properties of pure elements and their various compounds. Based on the constructed potential, molecular dynamic simulations are employed to study metallic glass formations and their local atomic arrangements. First, a glass-formation range is determined by comparing the stability of solid solutions and their corresponding counterparts, reflecting the possible composition region energetically favored for the formation of amorphous phases. Second, a favored glass-formation composition subregion around Al0.05Ni0.35Ti0.60 is determined by calculating the amorphous driving forces from crystalline-to-amorphous transition. Moreover, various structural analysis methods are used to characterize the local atomic arrangements of Al0.05NixTi0.95-x metallic glasses. We find that the amorphous driving force is positively correlated with glass-formation ability. It is worth noting that the addition of Ni significantly increases the amorphous driving force configurations of fivefold symmetry and structural disorder in Al0.05NixTi0.95-x metallic glasses until the content of Ni reaches approximately 35 at%.
