Ion beam mixing of metal-ceramic interfaces

Ion beam induced surface and interface engineering

“…The basic mass transport mechanisms in ceramics are much more complex than in metals. Different displacement energies and masses lead to different behaviour during cascade mixing [474].…”

Temperature-dependent ion-beam mixing in amorphous SiOC/crystalline Fe composite

“…Previous studies mainly focus on mixing in either crystalline/crystalline or amorphous/amorphous systems. [2,3,28,29] One observation was that ion mixing in amorphous materials exceeds 2-3 times than that observed in the crystalline counterpart, which was attributed to the more open structure and less longrange order in amorphous solids. [30] At present, the crystalline metal/amorphous ceramic interface response to ion mixing is still largely unknown.…”

“…[1] In the case of composited systems containing two or more different materials, the most obvious example is ion mixing and alloying during ion irradiation which can occur at their interfaces. [2][3][4] As one of few measureable quantities which is directly CONTACT Qing Su qsu3@unl.edu correlated to damage level, ion mixing has been studied in many solids. [5] Previous systematic experimental results have shown that not only irradiation parameters (such as temperature, dose and dose rate but materials properties (such as heat of mixing and cohesive energy) influence the ion mixing process.…”

Ion beam mixing at the Fe2O3/Al2O3 interface

“…A paramagneticmagnetic transition has been observed for xϾ0. 5 2 In this last experiment it was shown that the extent of mixing is limited to 12% and that, even if FeAl 2 O 4 was formed, the main component was nonstoichiometric FeO. By adjusting the thickness of the deposited Fe 2 O 3 layer, the energy and the fluence of the impinging ions, the ion beam mixing technique is a promising method to create this spinel phase in order to constitute a thermal barrier since, as it was mentioned in the introduction, hercynite is interesting for its refractory properties.…”
