“…When Mo reacted with Ni atom it can be analyzed that powerful metal-belt took shape and the shell storey of the electron retrenches and the nucleus's attraction to the outer sphere's electron power [9][10][11]. And then the order atom clusters in long distance were messed while the short distance unchanged, the characteristic of amorphous diffraction became more evident [12][13]. When the Mo atom content is even more(33.46at.%), as fig.…”

A variety of foamed Ni-Mo alloys coatings have been obtained using pulsed electrodeposition technique. The deposit is mainly composed of amorphous structural through the X-ray diffractions (XRD), the morphology clearly contains large amounts of multi-bubble pore structure with pentagonal or hexagonal skeleton structure and obviously stratifys through scanning electron microscopy (SEM) experimentals. This pentagonal or hexagonal skeleton structure and obvious stratification has a larger surface area. The electrolysis experiments show that such foamed alloys have a low hydrogen evolution overpotential and a better corrosion resistance in 25°C, 7mol·L-1 KOH alkaline solution.

“…With the Mo content reach to 28at.%(fig. 1), the diffraction of alloy appeared a double-shoulders peak in which related to the priority growth orientation of reduced atoms in the process of formation alloy coating, With the decreased of complexing agent, the reduction degree of MoO 4 2is decreased, which effect the multi-reduction process of Mo atoms [13,14] . So that in the process of formation alloy structure the atoms formed complex space structure under the force of outer high speed revolving electron.…”

Using X-ray diffraction (XRD), scanning electron microscope (SEM) and transmission electron microscope (TEM) to describe the relationship between Mo content and the amorphous content in deposites from the effects of the molybdate concentration on microstructure, phase content and morphology of the deposits. It is found when the Mo content is low to 18at.%, the deposits are composed of nanocrystalline main phases and the grain size is below 10nm with tiny particle at the basement surface. When Mo in 18~33at.%, the deposits are composed of amorphous phase up to more than 60wt.% proportion, and the grain size of the nanocrystalline existing in the deposits is stability of 3~10nm with tiny particle and well-distribution of the basement surface. When Mo content is exceeding 33at.%, the deposits performance is of the crystalline properties with more crystal defects in the coating.

“…However, it is often the case that the bulk phase diagram is not an accurate way to predict surface behavior and, in that sense, the Sn-Au system seems to be a good example of that. In this work, we apply the quantum approximate method [11][12][13] Here, it suffices to indicate that the method describes any atomic arrangement in terms of individual contributions ε i of each atom to the total energy of formation of the system, ∆H = Σε i . Each contribution ε i consists of a strain energy term, ε i,s , a chemical energy term, ε i,c , and a coupling function, g i , linking both contributions, so that ε i = ε i,s + g i ε i,c .…”
