ʻO nā ʻano nui o nā papa titanium

E like me nā kūlana like ʻole, hiki ke hoʻokaʻawale ʻia nā papa titanium i nā ʻano he nui. Wahi a ka haku mele, ua hoʻokaʻawale ʻia nā papa titanium i ʻelua mau ʻāpana: nā papa titanium maʻemaʻe a me nā pā titanium alloy. Hoʻokaʻawale ʻia nā papa titanium maʻemaʻe i nā māka e like me TA1, TA2, a me TA3 e like me nā maʻemaʻe like ʻole. E emi ana ka ma'ema'e a mahuahua ka ikaika. Loaʻa i nā papa titanium maʻemaʻe ka plasticity maikaʻi a me nā waiwai welding a hoʻohana pinepine ʻia i nā mea kemika a me nā mea hoʻonaninani.

Hoʻohui ʻia nā mea ʻē aʻe (e like me ka alumini, vanadium, molybdenum, a me nā mea ʻē aʻe) i ka titanium maʻemaʻe e hoʻomaikaʻi i kāna hana. ʻO nā pā kila titanium maʻamau ka TC4 (Ti-6Al-4V), TC11 (Ti-6.5Al-3.5Mo-1.5Zr-0.3Si), a me nā mea'ē aʻe. Loaʻa iā ia ka ikaika kiʻekiʻe, ke kūpaʻa wela maikaʻi a me ka pale ʻana i ka corrosion, a hoʻohana nui ʻia i ka aerospace a me nā kahua lapaʻau. Hiki i ka tensile ikaika o TC4 titanium plate ke piʻi aku ma mua o 895 MPa, a hiki i ka mahana hana ke hiki i 400 degere.

E like me ke kaʻina hana, hiki ke hoʻokaʻawale ʻia nā pā titanium i nā pā -wili a me nā pā anu-wili. 'Oloka'a 'ia nā papa 'oloka wela ma luna o ka mahana ho'ohāhā, 'o ka ma'amau me ka mānoanoa 'oi a'e ma mua o 3 mm, a he ikaika a 'o'ole'a. 'Oloka'a 'ia nā papa anuu -ma ka lumi wela, 'oi aku ka lahilahi (ma'amau ma lalo o 3 mm), he ili laumania, a he pololei ka nui. Eia kekahi, aia nā papa huila titanium, i hana ʻia e ka pahū pahū a i ʻole ka ʻōwili ʻana i nā papa titanium me nā metala ʻē aʻe (e like me ke kila, aluminika, etc.). Loaʻa iā lākou ka pale corrosion o ka titanium a me ka ikaika o ka substrate, a hoʻohana pinepine ʻia i nā mea kemika a me ka ʻenekinia moana.
