Titanium Aluminum Carbide

(Titanium Aluminum Carbide)

ʻIke ʻia no kona kūpaʻa haʻalulu wela maikaʻi loa, ʻo ka titanium alumini carbide pauka pū kekahi me ka modulus mechanical kiʻekiʻe a me ka conductivity. Hoʻohana ʻia ia ma ke ʻano he precursor no nā MXenes a me nā nanomaterials. Hoʻohana ʻia ia i nā mea hoʻomehana wela kiʻekiʻe, nā mea anti-corrosion kemika a me nā pākahi lithium ion.

ʻO ka Titanium-aluminum carbide kahi nitride hoʻololi bidimensional transition i loaʻa i ka nānā nui ʻana i ka noiʻi ʻepekema waiwai. Loaʻa i ka Ti3AlC2 ke kūpaʻa oxidation kūʻokoʻa, ka machinability maikaʻi a me ke kūpaʻa wela kiʻekiʻe. ʻO ke ʻano o ka pae ua like ia me nā seramika. Hoʻohana nui ʻia ia i nā mea seramika kūikawā Max.

Pono ka synthesis o nā pauka Ti3AlC2 maikaʻi i kahi kaʻina hana hou. Hoʻopili ʻia kēia māhele e ke ʻano e pili ana i nā paʻakai hoʻoheheʻe ʻia, e hana ana ma ke ʻano he ʻano hana. I loko o ke kaʻina hana synthesis, hana ka paʻakai hoʻoheheʻe ʻia ma ke ʻano he mea hoʻohālikelike e pale aku i nā reactants mai ka oxidizing i ka wā o ke kaʻina hana synthesis kiʻekiʻe.

ʻO ka nui o kēia māhele he 4.2 g cm-3. Paʻa ia a hiki i 1400 degC. He haʻahaʻa haʻahaʻa hoʻonui hoʻonui a me ka paʻakikī Vickers. ʻO nā kristal he ʻano cubic i waena o ka maka. Aia kona nui aniani mai ka 0.1 a 0.3 mm.

Ma waho aʻe o ka lilo ʻana i mea precursor no MXenes a me nā nanomaterials, hiki ke hoʻohana ʻia ka titanium-aluminum carbide ma ke ʻano he mea hoʻolālā kiʻekiʻe. Maikaʻi kona ikaika a me ke kaumaha. ʻOi aku ka maikaʻi o ka pale ʻana i ka corrosion o kēia mea. Hiki ke hoʻohana ʻia i nā laina hoʻoili uila no ka mea he māmā ke kaumaha.

ʻOkoʻa nā morphologies o kēia mea, e pili ana i kona mau waiwai. Hoʻopili lākou i ka hoʻonui ʻana i ka spacing layer a hoʻemi i ka impedance.
