It is seen from the Fig. 3 (a) that the peak around -7 eV is due to mainly ‘s’ states of Al and the number of DOS at Fermi level N (EF) is 1.42 States/eV (Table 1).
One of the standard methods is to calculate the Debye temperature from elastic constants data, since θD may be estimated from the average sound velocity vm by the following equation [24, 25]: (2) where h is Plank’s constant, kB is Boltzmann’s constant, Va is the atomic volume, n is the number of atoms per formula unit and vm is average sound velocity.

The choice of graphite as an electrode material is justified by a number of its advantages: - when interacting with titanium forms carbides with high wear resistance; - inclusions of graphite increase antifriction properties, since graphite in a free state is a solid lubricant; - no inert or reducing environment is required, doping may occur in the open air; - when doping with graphite electrodes, the dimensions of the parts practically do not change, which is an important advantage.
In most cases, the sequence of formation of zones, their number, structure and properties depend on the processing conditions discussed above.
The zone of plastic deformation is characterized by the grinding of grains, the formation of large dislocations, as well as the change in lattice parameters.

The first 10 samples (numbered in table 1-10) were made with the spot time as variable - the energy (current and voltage) remaining constant (Is = 125 A, Ua = 19.1 V) - and the following 10 (numbered from 11 at 20) the energy (intensity and voltage) changed - the spot time been kept constant, tp = 0.8 s.
Microscopic images of metallographic analysis of welded spots (x100) During the microscopic analysis of the samples in the characteristic areas, a homogeneous structure was noted, with the presence in majority of a dendritic casting structure with possible traces of eutectic at the grain boundary, specific to aluminum alloys.

The result will inevitably lead to that a number of important engineering indices of laterite dam gradually deteriorated.
The results can be obtained by equation: Dm=(1-Pwe)Ne/(1-Pe)Nwe, where Dm is the deconstruction degree, Pwe and Pe are average porosity of laterite samples without erosion and eroded respectively, Nwe and Ue are particle numbers of laterite samples without erosion and eroded respectively.

Because of the extremely low sintering activity of these coarse-grained alumina, no sufficient strength can be obtained unless the sintering temperature reaches 1700℃ or higher.
It was found that with increasing amounts of aluminum hydroxide, the number of small alumina particles also increases.
It also can be seen that when the amount of aluminum hydroxide is too low (Fig.2(c)), the number of decomposed small particles is lower and the strengthening effect is weakened.

The refractive index and porosity were found to vary with treatment temperature and number of dippings.
The latter are due probably to the progress in the formation of the anatase phase and to the increase of the size of the grains.
Fig. 7: Characteristics Intensity Potential of TiO2 thin films obtained after annealing at 450°C for various numbers of dippings: 1(a) and 2 layers (b).
