Triethanolamine (TEA)/graphene oxide (GO) composite coatings were prepared by electrodeposition on magnesium alloy AZ91. The morphology, structure, and corrosion behaviors of the composite coatings for Mg alloy in the 3.5 wt % NaCl solution were studied by scanning electron microscopy, X-ray diffraction spectroscopy, X-ray photoelectron spectroscopy, Raman spectroscopy, electrochemical tests, immersion experiments, and quantum chemical calculation. The results indicated that the TEA/GO composite coatings were distributed evenly on the Mg alloy substrate. The electrochemical tests showed that the composite coating had lower corrosion current density and higher film resistance. The corrosion process of the composite coatings for Mg alloy in the 3.5 wt % NaCl solution could be separated into three processes, and the physical models were set up. The quantum chemical calculation indicated that TEA and GO could be adsorbed on the Mg alloy surface to exhibit a good barrier between the substrate and corrosive medium to prevent the aggressive ions from the substrate surface.

“…Next, to consider the industrial applications of the energetic ion irradiation to the hardness modification of dilute aluminum alloys, we discuss the experimental results for two practical aluminum alloys, Al-Cu-Mg alloy [7,8] and Al-Mg-Si alloy [9,17]. The former is a practical aluminum alloy that is best known as "Duralumin", and the latter has been used as electrical wire material because of its good electrical conductivity.…”

“…However, such studies for nuclear power plants and space developments have treated the negative effects of ion irradiation (so-called "radiation damage") on materials' properties. In our recent studies, we have positively used the energies deposited by energetic ion/electron irradiation for the modification of materials properties such as the mechanical properties [7][8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23], magnetic properties [24][25][26][27][28][29][30][31][32][33][34][35][36][37], and optical properties [38] of metallic and oxide materials.…”

The former is an example of the materials' modification through the irradiation-enhanced process, and the latter is that through the irradiation-induced process.…”

When materials are irradiated with high-energy ions, their energies are transferred to electrons and atoms in materials, and the lattice structures of the materials are largely changed to metastable or non-thermal equilibrium states, causing the modification of several physical properties. There are two processes for the material modification by ion irradiation; one is “the irradiation-enhanced process”, and the other is “the irradiation-induced process”. In this review, two kinds of recent results for the microstructural changes and the modifications of mechanical properties will be summarized: one is the hardness modification of dilute aluminum alloys, which is a result of the irradiation-enhanced process, and the other is the hardness modification of Ni-based intermetallic compounds as a result of the irradiation-induced process. The effect of the subsequent thermal treatment on the microstructures and the hardness for ion-irradiated dilute aluminum alloys is quite different from that for Ni-based intermetallic compounds. This result reflects the difference between the irradiation-enhanced process and the irradiation-induced process. Finally, possibilities of the ion irradiation and subsequent thermal treatment to industrial applications will also be discussed.
