When water enters the coating, polar-polar bonds (between the metal hydroxide at the interface and the coatings) are eliminated at the individual sites causing a reduction in the adhesive strength (an exchange of polar-polar adhesion sites with water.)
The experimental data shows that the moisture weight gain reached about 0.38% after a period of about 31days.

These data on property tests show that the material vinizol has all the necessary positive consumer characteristics, which ensures its prospects and competitiveness in the construction industry.
Figure 1 shows the dependence of the total hydrocarbon emission reduction on the sorbent additive dosage (coke dust, samples № 1 and 2).
The table data shows that the samples of asphalt mixtures with the addition of BOF slag and carbon-mineral sorbents in terms of quality not inferior to the original asphalt mix classical composition.

Data for alloyed alloys of the (Fe-Ni-Co) system from [17, 18] were used in the calculations.
The data shown in Fig 2 а correspond to the 'MQ GAP' of the weighted average and for the 'C' fraction with Dm ≤ 2 μm (fig. 2 b).
The data and results of the scanning electron microscopy 'MQ GAP' studies of alloy No. 4 (Fe78Nd15B7) are shown in Figure 3.
The intergranular interface is indeed enriched in neodymium and contains uniformly distributed boron, as shown by the comparison of the experimental data.
Fig. 4 shows the SCVID magnetometry data.

In-depth XPS data were obtained after periodical ion etching of the studied surface with 3 keV Ar+ ions (45° incidence angle, a raster area of 1 cm × 1 cm).
The corresponding concentration profile of the in-depth spatial distribution of Si implants was derived from analysis of in-depth XPS data.
The dashed line represents the linear fit to the RSD data within the range VG = 12 – 30 V.
Using data from DC measurements, one can experimentally assess the ECR value.
By linear fit to the RSD data in this range (Fig. 6c) we get the value 160 kW (that is, actually, the mean RSD value in this range).

Introduction General tendencies in creating designs of advanced engineering structures of different functional area in many industries (chemical and food, power engineering and shipbuilding, aerospace manufacturing, etc.) are associated with a reduction in mass of products [1-5], with the use of materials having improved mechanical [6-9] and operational characteristics [9-13], and also with the introduction of modern treatment technologies [14-18].
The analysis of the obtained data allows confirming that based on this value all the obtained welds meet the specified requirements.
The analysis of the data in Table 3 allows confirming that the required values were reached.
As is seen from the data in Table 3, for some angles of welding, negative values are specified, indicating the presence of weld depression, which, according to DSTU EN ISO 13919-1: 2015, for 3 mm thick welded joints of AISI321stainless steel produced by laser welding, should not exceed 0.3 mm.
As a result of the analysis of the abovementioned data, it was proposed to carry out further experiments on laser welding of butt joints of 2.0 mm thick aluminum AMg6M alloy in the vertical position (welding at the angle of 90°), i.e., to do uphill welding in order to provide a stable formation of a high-quality welded joint and to prevent the failure of laser equipment.

Introduction Optical communication implies the transfer of data/information from one point to another using light, usually over long distances [1].
The foundation of the LASER gave a sensible optical source fit for transmission of high data rate information [6].
A major reduction in threshold current was brought about by the introduction of a quantum well structure into the active region of surface emitting lasers [13].

The commercial code MICRESS [6,7,57] can directly be coupled with Thermo-calc to provide input of thermodynamic data.
Again a very good agreement between experimental data and simulation results is obtained.
The frames give exactly the same data as figure 9a, but the colour scale now runs from 0.027 wt% to 0.2 wt%.
The second drawback is the lack of experimental validation and quantitative data.
Lack of quantitative data applies especially to the nucleation behaviour and the interface mobility.

The experimental data were refined using the Rietveld method.
The summarized data on synthesized particles is listed in table 4 below.

And its water reduction rate is above 25%.
At this stage, the fly ash which reduces the alkalinity of the concrete is the most influential factors in reduction of concrete resistance towards cerbonation.
