The article studied the effect of annealing on the structure and properties of zirconium dioxide coatings obtained by detonation spraying. Detonation spraying was realized on a computerized detonation spraying complex of the new generation CCDS2000. Determined that coatings made of zirconium dioxide are characterized by high adhesive strength of adherence to the substrate. Thermal annealing of coated samples was performed at temperatures of 900-1200◦ C. It was determined that the microhardness of zirconium dioxide coatings increases by 10-25% depending on the annealing temperature after annealing. The results of nanoindentation showed that the nanohardness of the coatings after annealing at 1000◦ C increases by 50%. It was determined that after annealing at 1000◦ C, the elastic modulus of the coatings increases, which indicates a decrease in plasticity and an increase in the strength of the coatings. X-ray diffraction analysis showed that the phase composition of coatings before and after annealing consists of t-ZrO2. After annealing occurs there is an increase in the degree of t-ZrO2 tetragonality. Electron microscopic analysis showed that an increase in the number and size of micro-continuity in the form of thin layers after annealing. Determined that increase the hardness of zirconium dioxide after annealing at 900-1200◦ C is associated with a higher degree of tetragonality t-ZrO2 phase.

“…Воздействие на некоторые классы диэлектриков заряженных частиц излучений радиационных поясов Земли может приводить к аккумулированию этих зарядов в объеме и на поверхности таких материалов. Нескомпенсированность электрических зарядов в диэлектриках -к электрическому пробою и механическому разрушению элементов, например, терморегулирующих покрытий, оптических стекол на внешней поверхности КА, изменению их оптических и других свойств, за счет радиационно-стимулированных процессов, вызывают структурные и фазовые изменения [4][5][6][7][8][9][10][11]. Исследования в области синтеза высокочистых материалов показали, что нанопорошки силикатов цинка, циркония, легированные оксидами иттрия, церия, и др.…”

Исследовалось влияние электронного облучения на оптические свойства терморегулирующих покрытий- силиката цинка. Образцы получены методам гидротермального микроволнового (ГТМВ) синтеза. Для изучения радиационной стойкости, взаимосвязи между структурами и характеристиками материалов использованы методы спектроскопического и структурного анализа. Результаты сканирующей электронной микроскопии, фотолюминесценции, коэффициента диффузного отражения и поглощения показали, что покрытия на основе CeZn2SiO4 обладают высокой радиационной стойкостью по сравнению с чистым Zn2SiO4.

To solve the poor sustainability of electroactive stimulation in clinical therapy, a strategy of combining a piezoelectric BaTiO 3 -coated Ti6Al4V scaffold and lowintensity pulsed ultrasound (LIPUS) was unveiled and named here as piezodynamic therapy. Thus, cell behavior could be regulated phenomenally by force and electricity simultaneously. First, BaTiO 3 was deposited uniformly on the surface of the threedimensional (3D) printed porous Ti6Al4V scaffold, which endowed the scaffold with excellent force−electricity responsiveness under pulsed ultrasound exposure. The results of live/dead staining, cell scanning electron microscopy, and F-actin staining showed that cells had better viability, better pseudo-foot adhesion, and more muscular actin bundles when they underwent the piezodynamic effect of ultrasound and piezoelectric coating. This piezodynamic therapy activated more mitochondria at the initial stage that intervened in the cell cycle by promoting cells' proliferation and weakened the apoptotic damage. The quantitative real-time polymerase chain reaction data further confirmed that the costimulation of the ultrasound and the piezoelectric scaffolds could trigger adequate current to upregulated the expression of osteogenic-related genes. The continuous electric cues could be generated by the BaTiO 3 -coated scaffold and intermittent LIPUS stimulation; thereon, more efficient bone healing would be promoted by piezodynamic therapy in future treatment.
