ʻO nā hiʻohiʻona kumu a me nā pono waiwai o nā koʻokoʻo Titanium

ʻO ka nui o nā koʻokoʻo titanium he 4.51g/cm³ wale nō, ma kahi o 60% o ke kila, akā ʻoi aku kona ikaika kikoʻī (ratio o ka ikaika i ka density) ma mua o ka hapa nui o nā kila kila a me nā alumini alumini. ʻO ka lawe ʻana i nā koʻokoʻo titanium TC4 (Ti-6Al-4V) ma ke ʻano he laʻana, hiki i kona ikaika tensile ke hiki i 895MPa, e like me ke kiʻekiʻe o ke kila ikaika, akā ua hoʻemi nui ʻia ke kaumaha. ʻO kēia hiʻohiʻona ka mea i koho maikaʻi loa no nā ʻāpana aerospace e like me nā ʻāpana compressor mīkini mokulele a me nā pahu wahie rocket. Ma ke ʻano o ka pale ʻana i ka corrosion, e hoʻokumu ʻia kahi kiʻi ʻoniʻoni oxide ma ka ʻili o nā koʻokoʻo titanium, hiki ke pale aku i ka ʻāʻī ʻana o ka wai kai, chloride ion a me nā ʻano like ʻole a me nā media alkali. ʻO ke ola o ka lawelawe ʻana i nā pamu kemika a me nā kiwi a me nā mea hoʻomaʻemaʻe wai kai hiki ke piʻi ma mua o 10 mau manawa o nā mea kahiko. ʻO ka mea ʻoi aku ka maikaʻi, ʻo ka titanium maʻemaʻe (e like me TA1, TA2) a me kekahi mau alloys titanium e hōʻike ana i ka inertness biological maikaʻi loa a ʻaneʻane ʻaʻohe pane hōʻole me ka ʻiʻo o ke kanaka, e wehe ana i kahi ākea ma ke kahua o nā implants lapaʻau.
