ʻO nā mea waiwai o nā koʻokoʻo Titanium pili i ke koho noi

1. Kūleʻa maikaʻi i ka corrosion. Hōʻike ka Titanium alloys i ka pale ʻana i ka corrosion maikaʻi loa i ka lewa haʻahaʻa a me ka wai kai, ʻoi aku ka maikaʻi ma mua o ke kila kila. He kūpaʻa ikaika ia i ka pitting, acid corrosion a me ke koʻikoʻi koʻikoʻi, a hiki nō hoʻi ke pale maikaʻi i ka corrosion mai nā alkalis, chlorides, nā pūhui kūlohelohe o chlorine, nitric acid a me sulfuric acid. Eia nō naʻe, pono e hoʻomaopopo ʻia he nāwaliwali ka titanium i ka pale ʻana i ka corrosion i ka hōʻemi ʻana i ka oxygen a me ka media paʻakai chromium.

2. Hana maika'i ha'aha'a ha'aha'a. Hiki i nā huila Titanium ke mālama i ko lākou mau waiwai mekini maika'i ma lalo o nā kūlana ha'aha'a ha'aha'a ha'aha'a. No ka laʻana, hiki i nā huila titanium me ka haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e like me TA7, hiki ke mālama i kekahi plasticity ma kahi haʻahaʻa haʻahaʻa o -253 degere, e hoʻolilo iā ia i mea waiwai haʻahaʻa haʻahaʻa.

3. Hana kemika kiʻekiʻe. He hana kemika kiʻekiʻe ka Titanium a hiki ke hana ikaika me O, N, H, CO, CO2, mahu wai, amonia, a pēlā aku i ka lewa. Ke ʻoi aku ka nui o ke kalapona ma mua o 0.2%, e hoʻokumu ʻia ʻo TiC paʻakikī i ka alloy titanium; i nā wela kiʻekiʻe, e hoʻopuka pū ka pane me N i kahi papa ili TiN paʻakikī. Eia kekahi, ma kahi kiʻekiʻe o ka mahana wela ma luna o 600 degere, hoʻopau ka titanium i ka oxygen e hana i kahi papa paʻakikī me ka paʻakikī kiʻekiʻe loa, ʻoiai ka piʻi ʻana o ka ʻike hydrogen e alakaʻi i ka hoʻokumu ʻana i kahi papa brittle. ʻO kēia mau hopena kemika e hoʻopuka i kahi papa paʻakikī a palupalu ma ka ʻili titanium, me ka hohonu a hiki i ka 0.1 a 0.15 mm a me kahi degere paʻakikī ma kahi o 20% a 30%. I ka manawa like, ma muli o ke kiʻekiʻe kiʻekiʻe o ka titanium, maʻalahi hoʻi e pili i ka ʻili friction.

4. Li'ili'i thermal conductivity a me ka elasticity. ʻO ka thermal conductivity o ka titanium he 15.24W / (mK), ma kahi o 1/4 o ka nickel, 1/5 o ka hao, a me 1/14 o ka alumini, ʻoiai ka haʻahaʻa o ka thermal conductivity o ka titanium alloy ma mua o ka titanium, i hāʻule ma kahi o 50%. Eia kekahi, ʻo ka modulus elastic o ka titanium alloy e pili ana i ka hapalua o ke kila, ʻo ia hoʻi, ʻaʻohe rigidity maikaʻi a maʻalahi hoʻi e deform. No laila, ʻaʻole kūpono ia no ka hana ʻana i nā koʻokoʻo wiwi a me nā ʻāpana pā lahilahi. I ka wā o ka ʻoki ʻana, ʻoiai ʻo ka rebound o ka titanium alloy ma kahi o 2 a 3 mau manawa o ke kila kila, e hoʻoulu ai kēia i ka friction koʻikoʻi, adhesion a me ka hoʻopaʻa paʻa ʻana ma ke alo hope o ka mea hana.
