Brushite coatings were obtained on titanium by the method of electrochemical deposition from Ca(NO3)2/NH4H2PO4 electrolyte at Ca/P = 1.67, pH = 4 and a constant voltage of 15 V or a current density of 20 mA/cm2 for 20 min. In a medium of 0.01 – 0.10 % polyvinyl alcohol at a constant voltage of 15 V, are deposited single-phase brushite or monetite coatings are deposited. The addition of 0.01 – 0.10 % polyvinyl alcohol into the electrolyte during deposition at a constant current density of 20 mA/cm2 leads to the formation of composite calcium phosphate coatings containing brushite, calcium hydroxide and calcium phosphate of the apatite structure. The bioactivity of calcium phosphate coatings was confirmed by the formation of apatites during their soaking in the Simulated Body Fluid (SBF). Amorphized apatite formed on brushite coatings during 2 weeks soaking in SBF crystallizes into β-tricalcium phosphate after heat treatment. The apatite formed on the composite coating in the SBF crystallizes into a composition of hydroxyapatite and β-tricalcium phosphate. The resulting bioactive calcium phosphate coatings can be used as biocoatings to enhance osseointegration of titanium implants.

The stability of the workpiece during rolling depends on the compression stresses and the duration of the stresses. At low rolling speeds, creep deformation plays an important role. The influence of the accuracy of the shape of the workpiece and the location of the rolls and wires on improving the reliability of the mill is shown.

The interaction of Pr/Dy with oxygen in nickel melts at РAr = 0.1 MPa and constant temperature was studied by the method of instantaneous EMF fixation using a Mo[Cr/Cr2O3//ZrO2(MgO)//O(NiL)]Mo cell and certified sensors. Dependences a[O] = f[Pr/Dy, %] were expressed as logarithmic equations, which made it possible to compare them with each other in the concentration range of 0.001 – 0.2 % of each deoxidizer and determine that the deoxidizing capacity of Pr is 1.7 times higher in terms of compared to Dy. Calculated a[O] in Ni – O – Al – (Pr/Dy) melts compared to Al at a concentration of 0.05 % elements and showed a seven-fold decrease for the first deoxidizer and an eleven-fold decrease for the second. The morphology of non-metallic inclusions in metallographic sections of Ni – O – Pr/Dy alloys indicates that the inclusions are located along grain boundaries and have different configurations and complex heterophase composition. The analysis of non-metallic inclusions with the maximum content of the deoxidizing element proved the existence of Pr/Dy oxygen compounds, which confirms the data of thermodynamic and mass spectrometric studies. The average content of Zr in non-metallic inclusions during the deoxidation of Pr is twice as high as in the experiments during the deoxidation of Dy, which indicates the interaction of Pr/Dy with ZrO2 of the EMF sensor and the predominant interaction of Pr compared to Dy and correlates with the data on the determination of a[O].
采用Mo[Cr/Cr2O3//ZrO2(MgO)//O(NiL)]Mo电池和认证传感器，研究了在РAr = 0.1 MPa和恒温条件下镍熔体中Pr/Dy与氧的瞬时电磁场固定方法。依赖性[O] = f(公关/ Dy, %)被表示为对数方程,这使它可以相互比较的浓度范围0.001 - 0.2%的脱氧剂和确定公关的脱氧能力高1.7倍计算Dy相比。[O]在Ni - O - Al -(公关/ Dy)融化而元素和艾尔的浓度0.05%显示7倍减少第一脱氧剂和eleven-fold减少第二。Ni - O - Pr/Dy合金金相断面中非金属夹杂物的形貌表明，这些夹杂物沿晶界分布，具有不同的形态和复杂的异相组成。对脱氧元素含量最高的非金属夹杂物的分析证实了Pr/Dy氧化合物的存在，这证实了热力学和质谱研究的数据。Pr脱氧过程中非金属夹杂体中Zr的平均含量是实验中Dy脱氧过程中Zr的两倍，这说明了EMF传感器中Pr/Dy与ZrO2的相互作用，Pr与Dy的相互作用占主导地位，这与a[O]的测定数据有关。

The work investigated the deformations of materials arising from the action of high-power laser pulses. Composite mechanoluminescent materials based on a polymer and a phosphor powder were used to visualize and record the dynamics of the development of deformations. Mechanoluminescent materials were applied to the surface of the materials under study. It is shown that the spatial distribution of the glow intensity of the mechanoluminescent layer and the rate of its change make it possible to judge the magnitude and rate of deformation of materials when they are exposed to laser pulses. The kinetics and photoluminescence spectrum of composite materials were studied under the combined action of short-wave and long-wave laser radiation. It is shown that the photoluminescence excited by a long-wavelength laser is associated with the activation of the populated levels of the traps.

Using atomic-emission analysis with inductively coupled plasma (AES – ICP) and atomic absorption spectroscopy (AAS) were developed methods, which allow rapidly, with good metrological characteristics without prior separation of the matrix and without the use of standard composition samples to determine impurity elements (Ag, Cu, Fe, Zn) of concentrations from 0.0005 to 10 % in medical materials based on calcium phosphate. The relative standard deviation (Sr) is 0.05 – 0.005 at the elements contents from 1 to 10 % and does not exceed 0.15 at the elements contents from 0.0005 to 0.1 %. New analytical control methods have provided research on the development of medical composite materials based on substituted calcium phosphates exhibiting antibacterial activity.

The quality of heat-resistant coatings deposited by flame spraying is largely determined by the adhesion of the coating to the surface of the part. One of the ways to increase adhesion is to deposition intermediate layers of thermosetting powders between the base material and the coating. In this work, two versions of heat-protective coatings are investigated — a two-layer coating consisting of an Al – Ni sublayer (20 – 80 wt. %) and a main ZrO2 layer, and a single-layer coating sprayed from an aluminum-clad zirconium oxide powder (20 ZrO2 – 80 Al, wt. % ). The method of differential thermal analysis was used to determine the temperature ranges and values of the exothermic effects of oxidation and redox reactions during heating of Al – Ni and ZrO2 clad powders. A significant exothermic effect was found during oxidation of the aluminum cladding shell in the temperature range of 360 °C and a stronger thermal effect due to the redox reaction at a temperature of 920 °C. The microstructure and microhardness of the obtained coatings have been studied, and their thermal conductivity and adhesion have been assessed. The resistance of the coatings during thermal cycling tests has been determined. It has been established that thermal protective coatings made of aluminum-clad zirconium oxide powder have the best characteristics under thermal cycling conditions. A higher level of adhesion and thermal cyclic resistance of such coatings are due to an increase in the enthalpy of aluminum-clad ZrO2 powders due to exothermic reactions and the presence of a metal binder.
