Ti3AlC2
ʻO ka alumini titanium carbide he mea hou me ka ternary layered structure, nona nā waiwai kūʻokoʻa, Ua loaʻa iā ia ka nānā nui mai nā mea ʻepekema a me nā physicists. ʻO ka alumini titanium carbide (Ti3AIC2) no ka ʻōnaehana kristal hexagonal a loaʻa iā ia nā ʻano o nā metala a me nā seramika: ua like ka conductivity a me ka thermal conductivity e like me nā metala, akā loaʻa pū kekahi modulus elastic kiʻekiʻe a me nā waiwai mechanical kiʻekiʻe kiʻekiʻe e like me nā seramika. He maikaʻi conductivity, thermal conductivity a me kiʻekiʻe elastic modulus.A haʻahaʻa Vickers paakiki, maikai kū'ē i ka poino; Hiki ke hana i ka ʻoki ʻana i ka lumi wela a me ka deformation plastic i ka wela kiʻekiʻe; Loaʻa iā ia ke kūpaʻa kiʻekiʻe-menahana maikaʻi a me ke kūpaʻa oxidation. I ka manawa like, loaʻa iā ia ke kūpaʻa haʻalulu wela maikaʻi, ka pale ʻana i ka pōʻino a me ke kūpaʻa kino kino maikaʻi.

Ti3SiC2
Hoʻohana ʻia ka pauka Ti3SiC2 ma ke ʻano he MAX mau mea seramika kūikawā, nā mea uila, nā mea hoʻolālā wela kiʻekiʻe, nā mea pulu electrode, nā mea anti-corrosion kemika a me nā mea wela wela.
Loaʻa i ka Titanium silicon carbide nā pono he nui o nā metala a me nā seramika. E like me ka metala, he mea hoʻokele maikaʻi ia o ka uila a me ka wela. He mea maʻalahi ke hana, palupalu, ʻaʻole ʻike i ka haʻalulu wela, a hōʻike i ka plasticity i nā wela kiʻekiʻe. He kūpaʻa nō hoʻi ia i ka oxidation a me ka wela kiʻekiʻe e like me nā keramika. ʻOi aku ka ikaika o ka wela kiʻekiʻe ma mua o nā mea wela wela a pau.
Ma ke ʻano he mea wela kiʻekiʻe, loaʻa iā Ti3SiC2 kahi conductivity uila ʻelua o ka graphite. ʻAʻole hiki ke ʻaʻahu a loaʻa iā ia nā pōmaikaʻi e like me ka pulupulu no nā kaʻa AC transitional. ʻO kona ikaika wela kiʻekiʻe, ke kūpaʻa oxidation, a me ke kūpaʻa haʻalulu wela hiki ke hiki iā SiN. Hiki ke hoʻohana ʻia nā mea electrode hoʻoheheʻe metala ma muli o ko lākou kūpaʻa haʻalulu maikaʻi a me ka conductivity uila kiʻekiʻe. I ka hōʻuluʻulu ʻana, ʻo ka titanium silicon carbide kahi mea wela kiʻekiʻe me ka waiwai noiʻi koʻikoʻi a me nā manaʻo noi.
