ʻO ka hoʻomaka ʻana i nā pono o ka Nickel Titanium Alloy

ʻO ka Nitinol kahi hui hoʻomanaʻo hoʻomanaʻo. ʻO ka hoʻomanaʻo hoʻomanaʻo hoʻoheheʻe ʻia he mea hoʻohui kūikawā e hiki ke hoʻihoʻi hou i kāna deformation plastik i kona ʻano kumu ma kahi mahana kikoʻī, a loaʻa ka plasticity maikaʻi.
ʻOi aku ka nui o kona hoʻonui ʻana ma luna o 20%, ʻoi aku ka luhi o ka ola a hiki i 7 mau manawa o 1 * 10, ʻo nā hiʻohiʻona damping he 10 mau manawa kiʻekiʻe ma mua o nā pūnāwai maʻamau, a ʻoi aku ka maikaʻi o kona kūpaʻa ʻana ma mua o ke kila kila kila, no laila hiki iā ia ke hoʻokō i nā pono o nā ʻano like ʻole. ʻenekinia a me nā noiʻi olakino, a he ʻano mea hana maikaʻi loa ia.
Ma waho aʻe o ka hana hoʻomanaʻo kū hoʻokahi, loaʻa nā mea hoʻomanaʻo hoʻomanaʻo i nā hiʻohiʻona maikaʻi loa e like me ke kūpaʻa ʻaʻahu, ke kūpaʻa corrosion, ka damping kiʻekiʻe a me ka super elasticity.
(I) Ka Hoʻololi ʻana a me nā ʻano o nā Alloy Nickel-Titanium
E like me ka inoa e hōʻike nei, ʻo Ni-Ti alloy kahi hui binary i haku ʻia me ka nickel a me ka titanium, aia i ʻelua mau ʻano hana aniani like ʻole, austenite a me martensite, ma muli o ka loli ʻana o ka mahana a me ke kaomi mechanical. ʻO ke ʻano o ka hoʻololi ʻana o ka pae o ka alloy Ni-Ti i ka wā e hoʻoluʻu ai ka pae makua (austenite phase) - R phase - martensite phase. Rhombic ka māhele R, ʻo austenite ka mokuʻāina ke kiʻekiʻe ka mahana (ʻoi aku ka nui ma mua o ka like: ʻo ia hoʻi, ka mahana i hoʻomaka ai austenite), a i ʻole de-loaded (nā mana o waho e wehe i ka Deactivation), cubic, paʻakikī. ʻOi aku ka paʻa o ke ʻano. ʻO ka pae martensite he haʻahaʻa haʻahaʻa (emi ma mua o Mf: ʻo ia hoʻi, ka wela o ka hopena o ka martensite) a i ʻole ka hoʻouka ʻana (hoʻoulu ʻia e nā mana o waho) i ka wā o ka mokuʻāina, hexagonal, ductile, repetitive, liʻiliʻi paʻa, ʻoi aku ka maʻalahi o ka deformation.
(B) nā waiwai kūikawā o ka nickel-titanium alloy
1, ʻano hoʻomanaʻo hoʻomanaʻo (memo hoʻomanaʻo)
2、Superelasticity (superelasticity)
3、Ka ʻoluʻolu i ka hoʻololi ʻana i ka mahana ma ka waha waha.
4 、 Ke kū'ē i ka corrosion:
5, Anti-toxicity:
6, Ka ikaika orthodontic palupalu
7、Maikaʻi haʻalulu absorption waiwai
