Ua manaʻo ʻo Nikolai Kakhidze, he haumāna puka o ka Faculty of Physics and Engineering, i ka hoʻohana ʻana i nā nanoparticles daimana a i ʻole alumini oxide ma ke ʻano he ʻokoʻa i ka scandium pipiʻi no ka hoʻopaʻa ʻana i nā alumini alumini. E kūʻai ana ka mea hou i 4 mau manawa ma mua o ka analog scandium me nā waiwai kino a me nā mechanical.
I kēia manawa, nui nā hui hana moku e hoʻoikaika nei e pani i ke kila kaumaha me nā mea māmā a me nā mea māmā. Ma kahi o ka hoʻonui ʻana i ka hiki ke lawe, hiki ke hoʻohana pono ʻia e hōʻemi i ka hoʻohana ʻana i ka wahie, e hōʻemi ana i nā hoʻokuʻu ʻino i ka lewa a hoʻonui i ka neʻe o ka moku a me ka wikiwiki i ka lawe ʻana i nā ukana. ʻO nā ʻoihana i ka ʻoihana halihali a me nā ʻoihana aerospace makemake pū kekahi i nā mea hou.
ʻO nā mea alumini matrix composite i hoʻololi ʻia me ka scandium i lilo i mea pani maikaʻi. Eia naʻe, ma muli o ke kumukūʻai kiʻekiʻe o ka scandium, ke hoʻomaka nei kahi ʻimi ikaika no kahi hoʻololi ʻoi aku ka uku. Ua manaʻo ʻo Nikolai Kakhidze e hoʻololi i ka scandium me ke daimana a i ʻole alumini oxide nanoparticles. ʻO kāna hana ʻo ia ka hoʻomohala ʻana i kahi ala no ka hoʻokomo pololei ʻana i nā nanopowders i loko o kahi hehee metala.
Ke hoʻokomo pololei ʻia i loko o ka heheʻe, hoʻohui ʻia nā nanoparticles i agglomerates, oxidized, ʻaʻole i hoʻomālu ʻia, a hana lākou i nā pores a puni lākou iho. ʻO ka hopena, loaʻa nā mea haumia i makemake ʻole ʻia ma kahi o nā ʻāpana paʻakikī. I loko o ke keʻena o nā mea ikaika a me nā mea kūikawā ma ke Kulanui o Tomsk State, ua hoʻomohala ʻo Sergey Vorozhtsov i nā ala ʻepekema a me ka ʻenehana no ka paʻakikī paʻakikī o ka alumini a me ka magnesium e hōʻoia i ka hoʻokomo pono ʻana o nā nanoparticles refractory i ka hehee a hoʻopau i nā pilikia o ka wettability a me ka flotation. .
- Ma muli o ka hoʻomohala ʻana o kaʻu mau hoa hana, hāʻawi kaʻu papahana i kēia hopena: ua hoʻokaʻawale ʻia nā nanopowders (mahele like ʻia) i loko o ka pauka alumini micro-sized me ka hoʻohana ʻana i nā hana ʻenehana. A laila hoʻohui ʻia kahi ligature mai kēia hui ʻana i lawa ka ʻenehana a kūpono hoʻi no ka hoʻohana ʻana i ka ʻoihana ma kahi ʻoihana ʻoihana. Ke hoʻokomo ʻia ka ligature i loko o ka heheʻe, hoʻomaʻamaʻa ʻia nā māla o waho e hoʻohele like i nā nanoparticles a hoʻonui hou i ka wettability. Hiki i ka hoʻokomo pololei ʻana o nā nanoparticles ke hoʻomaikaʻi i nā waiwai kino a me nā mechanical o ka alloy mua, - wehewehe ʻo Nikolai Kakhidze i ke ʻano o kāna hana.
Hoʻolālā ʻo Nikolai Kakhidze e loaʻa i nā pūʻulu hoʻokolohua mua o nā ligatures me nā nanoparticles no kā lākou hoʻokomo ʻana i ka hoʻoheheʻe ʻana ma ka hopena o 2020. Ma 2021, ua hoʻolālā ʻia e kiʻi i nā castings hoʻokolokolo a pale i nā pono waiwai naʻauao.
Hoʻonohonoho ka mana hou o ka waihona i nā kūlana hou no ka noiʻi reproducible, e hāʻawi ana i kahi ala hilinaʻi i…
