Проведены исследования по определению влияния наночастиц оксидов на структурообразование и эксплуатационные свойства сварных швов и плазменных покрытий. Определены способы введения нанодисперсных тугоплавких порошков в сварочную ванну и покрытия с учетом деактивации наночастиц порошка. Для ввода наночастиц в сварочную ванну и покрытия при напылении проводили, путем приготовления порошковой смеси, с помощью механохимической обработки в специальных високоенергонапряженных планетарных мельницах. Структурные исследования сварочных швов с нанооксиднимы добавками в сварочной ванне показали образования измельченной дисперсной структуры с микротвердостью 264-304 МПа. Определены среднестатистическое значение количества неметаллических включений. Механические испытания сварных швов показали рост как предела текучести, так и предела прочности при введении в сварочную ванну наноокислов титана и алюминия. Наиболее существенное влияние на эти показатели оказывает наноокислов алюминия в количестве 0,5 об.%, увеличивая предел текучести на 49% и предел прочности на 23%. На ударную вязкость наиболее влияет оксид титана в количестве 1 об.%., повышая ее значение примерно в 2 раза. В свою очередь, введение нанопорошка оксида алюминия в количестве 1,5об.%. в плазменные покрытия позволило уменьшить коэффициент трения и увеличить износостойкость покрытий в 2-3 раза.

Studies on the determination of the effect of nanoparticle oxides on structure formation and operational properties of welds and plasma coating. Identify ways of nanodisperse refractory powders in the weld pool and the deactivation of nano particles of powder. To enter the nanoparticles in the weld pool and cover when spraying was conducted by cooking the powder mixture, using Mechanochemical processing in special visokoenergonaprâžennyh planetary mills. Structural studies of the welded joints with nanooksidnimy additives in molten pool showed education crushed the dispersed structure with microhardness 264-304 MPA. The average value of non-metallic inclusions. Mechanical testing of welds have shown growth as the yield strength and tensile strength of weld pool in nanookislov titanium and aluminium. The most significant impact on these indicators is of aluminium nanookislov 0.5 vol%, increasing the yield to 49% and tensile strength at 23%. The impact is most affected by titanium oxide in 1 vol%., increasing its value at about 2 times. In turn, the introduction of aluminum oxide nanopowder of 1, 5ob.%. the plasma coating to reduce friction and increase wear resistance coatings in 2-3 times.

Conducted studies to determine the effect of oxide nanoparticles on structure and performance of the welds and plasma coatings. Ways of introducing nanodisperse refractory powders to the weld pool and cover with the deactivation of nanoparticles powder. To enter the nanoparticles in the molten pool during the deposition and the coating was carried out by preparing a powder mixture by mechanochemical processing in special visokoenergonapryazhennyh planetary mills. Structural studies of welds with nanooksidnimy additives in the weld pool showed the formation of ground dispersed structure with microhardness 264-304 MPa. Defined statistical mean value of the number of non-metallic inclusions. Mechanical testing welds showed growth as yield and tensile strength, when introduced into the weld pool nanookislov titanium and aluminum. The most significant effect on these parameters has nanookislov aluminum in an amount of 0.5 vol.%, The yield strength increases by 49% and the tensile strength by 23%. In most affects the toughness of titanium oxide in an amount of 1 vol.%., Increasing its value is about 2 times. In turn, the introduction of alumina nanopowder in quantity 1,5ob.%. in plasma coatings allowed to reduce friction and increase wear resistance of coatings by 2-3 times.

Studies conducted to determine the impact of oxides spectroscopy consequently and operational properties of weld seams and plasma coatings.Identified ways of introducing products are on republican in a weld bath tub and cover with the deactivate medicine powder. To enter medicine in a weld bath and coverage with напылении conducted,By coffee powder mixture, using a similar unit processing in special високоенергонапряженных planetary mills.Structural studies welding seams with нанооксиднимы additives in welding bath showed education chopped disperse structure with sputtered targets 264-304 MPA.Animal defined value for the number of non-metallic inclusion. Mechanical testing of the welds have shown growth in both yield stress,And tensile strength when imposing the weld bath наноокислов titanium and aluminum. The most significant impact on these indicators provides наноокислов aluminum in the number of 0.5 on the. %,Increasing tensile strength by 49% and tensile strength to 23 %. The impact the most affected by the number of titanium oxide 1 of. % ., thus increasing its value approximately in 2 times. In turn,Introduction нанопорошка aluminum oxide in the amount of 1.5. %. In plasma coverage has helped to reduce the coefficient of friction and increase durability coatings in 2-3 times.
