The rapid wear of working tools of agricultural machines and equipment lowers the productivity of labour and the quality of operations. The most important and, correspondingly, most ‘problematic’ loaded components of agricultural machines are soil cultivating working tools. The principal methods of increasing the service life of these components are to use new materials and hardening surfacing technologies. 相似文献

This paper compares the solid-state reactions underlying the synthesis of LiTa y Nb1 ? y O3 and Li x Na1 ? x Ta y Nb1 ? y O3 solid solutions with the use of Ta2y Nb2(1 ? y)O5 niobium tantalum pentoxides and a mechanical mixture of the Ta2O5 and Nb2O5 pentoxides. Our results demonstrate that the synthesis with the use of Ta2y Nb2(1 ? y)O5 allows phase-pure solid solutions to be obtained at substantially lower temperatures in comparison with a mechanical mixture of Ta2O5 and Nb2O5. 相似文献

Nonlinear optical properties of various glasses containing copper chloride nanocrystals have been studied at wavelengths of
532 and 1064 nm. It is established that the nonlinear optical response is manifested by the optical limiting of transmitted
radiation and consists of two, low- and high-threshold parts. The low-threshold response is related to a self-defocusing of
the radiation, while the high-threshold response is related to the phenomena of two-photon absorption, color center photogeneration,
and thermal lens formation. 相似文献

The structure and mechanical characteristics of ceramic Nb2O5 and ceramic materials produced from coprecipitated Nb2(1 ? y)Ta2y O5 pentoxides by a conventional ceramic processing technique and exposure to high-intensity light have been studied by scanning probe microscopy and Raman spectroscopy. 相似文献

The density of melts based on nickel of various grades (i.e., with various oxygen contents) is experimentally studied at 1500–1650°C
and p
Ar = 0.1 MPa, and the effect of alloying elements (Al, Re, W, Mo, Co) on this density is analyzed. As compared to liquid nickel,
the density of a Ni-6% Al melt decreases and that of Ni-(3–7)% Re and Ni-7% Re-(W,Mo,Co) melts increases. The difference between
the molar volume of the melt calculated from the experimental data and using the additivity rule is determined, and the structures
of the melts at 1823 K are found to have a low density. 相似文献
