ʻO Titanium alloy, ka iwi metala i hoʻokomo ʻia i loko o ke kino
Ma muli o ka holomua o ka nohona a me ka hoʻomohala ʻenehana, ua hoʻonui ka mākeke o nā biomaterials a ke ulu nei i ka wikiwiki. ʻO ASTM F136 Ti6Al4V ELI no nā hoʻokomo ʻokiʻoki a me nā mea hoʻololi o ka ʻiʻo paʻa e like me nā niho hana, nā ʻāmi hana, a me nā iwi hana e hoʻonui a ulu wikiwiki nei i ka māhele lāʻau biomaterial.
ʻO ka Titanium a me ka titanium alloy hoʻohana nui ʻia i ka ʻoihana nuklea, kemika, a me ka petrochemical, aerospace, nā mea haʻuki, nā niho a me nā prosthetics olakino. Koho pū ʻia nā mea hao Titanium ma ke ʻano he mea maikaʻi loa no ka hoʻololi a hoʻoponopono ʻana i nā ʻiʻo paʻa paʻa ʻole (nā noi biomedical structural). ʻO ka metala titanium maʻemaʻe he kūpaʻa maikaʻi loa ia, akā he maikaʻi ʻole ka biocompatibility a me nā waiwai mechanical holoʻokoʻa, haʻahaʻa haʻahaʻa, a he kumukūʻai ke hana, hiki ke hoʻololi maikaʻi ʻia e ka hiki ʻana mai o nā alloys titanium.
ʻO ke kila Titanium ma mua o ke kila kila, ka ʻenehana maʻemaʻe (CP) Nb, Cr-Co alloy a me CP-Ta a me nā noi lāʻau ʻē aʻe, ʻoi aku ma mua o nā koi o ka hana, no ka mea, e hoʻokumu ʻia kona ʻili i kahi papa oxide a hana i ke kūpaʻa corrosion maikaʻi loa a me ka modulus haʻahaʻa o ka elasticity. .
Lapaʻau titanium alloy mea ole wale non-toxic, a me ka mama, akā, he kiʻekiʻe kiko'ī ikaika, maikaʻi biocompatibility, a me ka corrosion kū'ē, hiki ke hoʻohana 'ia e like me implants i loko o ke kino kanaka, etc., He kūpono no ka lāʻau metala mea, a me ka titanium. i loko o ka ʻāʻī o ka honua he waiwai nui loa, hiki ke hoʻomohala hou aku, ʻo ia ka noi kūpono a hoʻohiki ʻia o nā mea ʻenehana biomedical.
I kēia manawa, ʻo ka titanium maʻemaʻe (TA1, TA2; ʻo TA1 ka titanium maʻemaʻe ma mua o 99.6%, ka titanium maʻemaʻe ma lalo o 99.6 ʻo TA2) a Ti-6Al-4V, Ti-5Al-2.5Fe, Ti-6Al-7Nb alloys i hoʻohana 'ia no ka surgical implants ua hoʻohana nui 'ia i loko o ka 'oihana lapaʻau, akā, i ka hou β-type titanium alloy me ka biocompatibility maikaʻi a me ka mechanical compatibility ua lilo ʻO ia ka ʻenehana hoʻohiki loa i loko. ke kahua o na laau lapaau.
I ka wā e hiki mai ana, e hoʻomohala ʻia ka ʻenehana hana o nā alloys titanium i ke kuhikuhi o ka modulus haʻahaʻa a me ka ikaika kiʻekiʻe, a mai ke ʻano hoʻomohala ʻana, e lilo nā β-type titanium alloys i alakaʻi no ka hoʻomohala ʻana i ka wā e hiki mai ana a me ka "alakaʻi" o ka lāʻau lapaʻau titanium alloy. makeke.
I kēia manawa, ua synthesized kā mākou mau mea noiʻi i ka alloy Ti-Zr no ka dentistry me ka pili ʻana i nā waiwai mechanical o Co-Cr alloy a me Type IV alloy i hoʻohana mau ʻia i ka hana lapaʻau, i manaʻo ʻia e lilo i mea hou titanium alloy no ka hoʻihoʻi ʻana i ka lua waha. Eia kekahi, ua hoʻolālā pū ko mākou ʻāina i ke ʻano TAMZ (Ti-Al-Mo-Zr, etc.) i ka lāʻau lapaʻau ponoʻī, ʻoi aku ka maikaʻi a me ke kumukūʻai, a kūpono no ka hana ʻana i nā pale niho a me nā apo paʻi.
Ua manaʻo ʻia me ka hoʻomohala ʻana o ka ʻepekema a me ka ʻenehana, ka noiʻi ma ʻO ASTM F136 Ti6Al4V ELI No ka Hoʻopaʻa ʻana a ʻoi aku ka hohonu a me ka paʻa o nā mea hoʻohui titanium ʻē aʻe.
