ʻO ke alumini alumini Titanium kahi pahu hoʻoheheʻe ʻia no ka waiho ʻana o ka ʻūhā. Hiki ke loaʻa nā pahuhopu alumini alumini Titanium me nā ʻano like ʻole ma ka hoʻoponopono ʻana i ka ʻike o ka titanium a me ka alumini i loko o kēia alloy. ʻO nā pūhui intermetallic Titanium alumini he mea paʻakikī a palupalu me ke kūpaʻa maikaʻi. Hoʻopili ʻia lākou me kahi papa o ka titanium alumini intermetallic pūhui ma luna o ka ʻili o nā mea ʻoki maʻamau, hiki ke hoʻolōʻihi i ke ola lawelawe o nā mea hana. Inā hoʻokō ʻia ka sputtering me ka nitrogen discharge arc e hoʻomaka ana, hiki ke loaʻa kahi paʻakikī kiʻekiʻe a me ka haʻahaʻa friction coefficient surface mask, kūpono loa ia no ka uhi ʻana o nā mea hana like ʻole, nā ʻāpana a me nā ʻāpana ʻē aʻe. No laila, loaʻa iā ia kahi manaʻo noi maikaʻi i ka ʻoihana mīkini.
He mea paʻakikī ka hoʻomākaukau ʻana i nā pahu hao alumini titanium. Wahi a ka papa hana o ka titanium alumini alumini, hiki ke hoʻokumu ʻia nā ʻano hui intermetallic ma waena o ka titanium a me ka alumini, e alakaʻi ana i ka hana brittleness i ka titanium alumini alumini. ʻOi loa inā ʻoi aku ka nui o ka alumini i loko o ka alloy ma mua o 50% (atomic ratio), ke emi koke nei ke kūpaʻa o ka oxidation o ka alloy a ua koʻikoʻi ka oxidation. I ka manawa like, hiki i ka hoʻonui exothermic i ka wā o ka alloying ke hana maʻalahi i nā bubbles, shrinkage pores, a me ka porosity, ka hopena i ka porosity kiʻekiʻe o ka alloy a hiki ʻole ke hoʻokō i nā koi koi o ka mea i manaʻo ʻia. ʻElua mau ala nui no ka hoʻomākaukau ʻana i nā alumini alumini titanium:
1、 Keʻano hoʻomehana ikaika o kēia manawa
Ke hoʻohana nei kēia ʻano hana i kahi mea hiki ke loaʻa ke kiʻekiʻe o kēia manawa, ka mea e wela ai i ka pauka titanium a me ka pauka alumini, e hoʻopili i ke kaomi, a hoʻoulu i ka alumini a me ka titanium e hana i nā pahuhopu alumini alumini titanium. ʻO ka nui o ka huahana pahu pahu titanium aluminika i hoʻomākaukau ʻia e kēia ʻano he> 99%, a ʻo ka nui o ka palaoa ʻo ≤ 100 μm. Maʻemaʻe> 99%. ʻO ka papa hana o ka titanium aluminum alloy target material he: titanium content o 5% a 75% (atomic ratio), a ʻo ke koena he alumini. ʻO kēia kaʻina hana he haʻahaʻa haʻahaʻa a me ka nui o ka huahana kiʻekiʻe, a hiki ke hoʻokō piha i nā koi o ka hana ʻoihana nui.
2、 Wela isostatic kaomi sintering ala
Hoʻohui kēia ʻano hana i ka pauka titanium a me ka pauka alumini, a laila e hoʻouka i ka pauka, ke kaomi isostatic ma mua o ke kaomi ʻana, ke kaʻina degassing, a laila ke kaomi ʻana i ka isostatic wela. ʻO ka mea hope loa, lawe ʻia ka sintering a me ka hana ʻana no ka loaʻa ʻana o ka titanium aluminum alloy target. ʻO ka pahu hao alumini titanium i hoʻomākaukau ʻia e kēia ʻano he mau hiʻohiʻona o ke kiʻekiʻe kiʻekiʻe, ʻaʻohe pores, ʻaʻohe porosity a me ka hoʻokaʻawale ʻana, ka hoʻohui like ʻana, a me nā kīʻaha maikaʻi. ʻO ke kaʻina hana kaomi isostatic wela i kēia manawa ke ala nui no ka hoʻomākaukau ʻana i nā pahu sputtering titanium aluminika i koi ʻia e ka ʻoihana uhi.
