ʻO nā hiʻohiʻona maikaʻi o nā pūnāwai alloy titanium
Loaʻa i nā pūnāwai huila Titanium nā mea maikaʻi o ka liʻiliʻi liʻiliʻi, māmā, kūpaʻa maikaʻi i ka corrosion, a me ke kūpaʻa luhi. No ka mea ʻoi aku ka nui o ka modulus shear o nā mea hao titanium ma mua o ke kila, ʻoi aku ka liʻiliʻi o ka nui o nā huli e pono ai ke pelu ʻia ma mua o nā pūnāwai kila. ʻOiai ua like ke kaumaha o nā mea ʻelua, pūnāwai huila titanium ʻoi aku ka māmā ma mua o nā pūnāwai kila no ka mea ʻoi aku ka liʻiliʻi o nā mea. I ka hapanui o nā hihia, ʻoi aku ka māmā o ke kaumaha o nā pūnāwai titanium alloy he 60% a 70% ma mua o nā pūnāwai kila, a hiki ke hoʻemi ʻia ke kiʻekiʻe o ka hoʻolālā kiʻekiʻe o nā puna wai titanium, ʻo ia ka 50% a 80% haʻahaʻa ma mua o nā puna kila.
ʻO kekahi mea maikaʻi o nā punawai titanium ka pale ʻana i ka corrosion. Ma nā ho'āʻo hoʻāʻo hoʻoluhi ʻana i ka paʻakai paʻakai, ua hoʻemi ʻia ke ola luhi o nā pūnāwai kila maʻamau e 50% i hoʻohālikelike ʻia i ka lewa. I ka hoʻāʻo like, ʻo ke ola luhi o ka pūnāwai titanium he 4% haʻahaʻa ma mua o ka lewa. Eia kekahi, ʻaʻole like me nā pūnāwai kila, pūnāwai huila titanium ʻaʻole pono i nā pale pale.
ʻO ka puna he ʻāpana kūikawā. Hoʻohana nui ʻia ia i nā ʻano hana like ʻole o ka hana ʻāina a me ke ola, e like me nā kaʻa, nā kaʻa kaʻa, nā paikikala, a me nā ala ʻē aʻe. Hoʻohana ʻia nā pūnāwai i nā mea e pono ai i kēlā me kēia lā e like me nā kamepiula, nā uaki, nā hoʻololi kukui, nā mea pāʻani, a me nā clips. , hoʻokani nui i ka hana o ka haʻalulu a me ka mālama ʻana i ka ikehu.
I nā makahiki i hala iho nei, ua lilo ka titanium alloy i koho hou no nā mea puna ma muli o kona ikaika kikoʻī kiʻekiʻe, modulus elastic haʻahaʻa, a me ke kūpaʻa maikaʻi. Hoʻohālikelike ʻia me nā pūnāwai kila, loaʻa i nā puna titanium nā pono o ka māmā, ka liʻiliʻi liʻiliʻi, a me ke alapine resonance kiʻekiʻe. ʻO ko lākou mānoanoa a me ka modulus elastic he hapalua wale nō ia o nā pūnāwai kila, akā ʻaneʻane like ko lākou ikaika me nā pūnāwai kila. Ma muli o kēia mau mea maikaʻi, hiki ke hoʻolālā ʻia nā pūnāwai titanium e loaʻa i nā anawaena liʻiliʻi, liʻiliʻi liʻiliʻi, a haʻahaʻa loa ke kaumaha ma mua o nā pūnāwai kila ma nā noi kūpono.
E pili ana i nā pūnāwai, ʻo ka ikaika kiʻekiʻe ka mea koʻikoʻi hana pono no nā mea, no laila kiʻekiʻe-ikaika beta titanium alloys, e like me Ti-3Al-8V-6Cr-4Mo-4Zr a me Timetal LCB (Ti-6.8Mo-4.5Fe-1.5Al) i hoʻohana ʻia e hana i nā puna.
