He aha nā pōmaikaʻi o ka paipu titanium?

ʻO ka paipu Titanium he mea metala hou i pani piha i ka hao a me ka paipu kila ma kekahi mau ʻano. No laila he aha ka mea e hoʻololi wikiwiki ai i nā paipu kuʻuna?

ʻEhia mau pōmaikaʻi no nā paipu titanium?

1. ʻO ka paipu Titanium he ikaika kikoʻī kiʻekiʻe. ʻO ka nui o ka nui o ka Titanium alloy ma kahi o 4.5g/cm3, ʻo 60% wale nō o ke kila, ʻoi aku ka ikaika o ka titanium maʻemaʻe i ka ikaika o ke kila maʻamau, a ʻoi aku ka ikaika o nā alloys titanium kiʻekiʻe ma mua o ka ikaika o ke kila kila. No laila, ʻoi aku ka nui o ka ikaika kikoʻī o ka titanium alloy (ikaika/density) ma mua o nā mea hana metala ʻē aʻe a hiki ke hana i nā ʻāpana o ka ikaika kiʻekiʻe, rigidity maikaʻi, a me nā ʻāpana māmā a me nā ʻāpana. I kēia manawa, hoʻohana nā mea ʻenekini mokulele, ka iwi, ka ʻili, nā mea hoʻopaʻa, nā mea hoʻokele, a me nā mea ʻē aʻe.

2. Loaʻa i nā paipu Titanium ka ikaika wela kiʻekiʻe. ʻO ka hoʻohana ʻana i ka mahana ma mua o ke alumini alumini he mau haneli kiʻekiʻe i ka mahana waena hiki ke hoʻomau i ka ikaika i koi ʻia, hiki i ka mahana o 450-500 ℃ hana lōʻihi o kēia mau ʻano ʻelua o nā alloys titanium i ka laulā o ʻO 150 ℃ a 500 ℃ ka ikaika kūikawā kiʻekiʻe, a me ka alumini alumini ma 150 ℃ ma mua o ka ikaika o ka emi ʻana. ʻO ka mahana hana o ka titanium alloy hiki ke hiki i 500 ℃, alumini alumini ma lalo o 200 ℃.

3. Loaʻa i ka paipu Titanium ke kūpaʻa ʻino maikaʻi. ʻOi aku ka maikaʻi o kona pale ʻana i ka ʻino ma mua o ke kila kila; ʻOi loa ka ikaika o ka luaʻi ʻana, ka ʻawaʻawa a me ke koʻikoʻi; alkali, chloride, chlorine organic mea, nitric acid, sulfuric acid, etc. Akā ʻo ka titanium he oxygen haʻahaʻa a ʻilihune ka paʻakai paʻakai media corrosion.

4. He maikaʻi ka hana haʻahaʻa haʻahaʻa haʻahaʻa. Titanium alloy i ka haʻahaʻa wela a me ka ultra-haʻahaʻa wela, hiki nō ke mālama i kona mechanical waiwai. ʻO ka hana haʻahaʻa haʻahaʻa maikaʻi, ʻo ka mea āpau he haʻahaʻa haʻahaʻa haʻahaʻa haʻahaʻa, e like me TA7, ma -253 ℃ hiki ke mālama i kahi pae o ka plasticity. No laila, ʻo ka titanium alloy kekahi mea koʻikoʻi haʻahaʻa haʻahaʻa.

5. He nui ka hana kemika o ka paipu titanium. ʻO ka hana kemika a Titanium, a me ka lewa O, N, H, CO, CO2, mahu wai, amonia, a me nā hopena kemika ikaika ʻē aʻe. ʻOi aku ka nui o ka carbon ma mua o 0.2%, e hana i kahi TiC paʻakikī i nā alloys titanium; nā wela kiʻekiʻe, a ʻo ke kuleana o N e hana pū i kahi papa paʻakikī o TiN; ma luna o 600 ℃, hoʻomoʻa ka titanium i ka oxygen e hana i kahi papa paʻakikī o ka paʻakikī kiʻekiʻe; piʻi ka maʻi hydrogen, akā ke hoʻokumu ʻia hoʻi o ka papa embrittlement. Nui nō hoʻi ka pilina kemika o Titanium, maʻalahi e hana i kahi mea hoʻopili me ka ʻili o ka friction.

6. He liʻiliʻi ka wela o ka paipu Titanium a me kahi modulus liʻiliʻi o ka elasticity. He liʻiliʻi ka conductivity thermal o Titanium, ʻO ka modulus liʻiliʻi o ka elasticity o ka titanium alloy modulus o ka elasticity e pili ana i ka 1/2 o ke kila, no laila ua ʻilihune kona rigidity, maʻalahi e hoʻololi, a ʻaʻole kūpono no ka hana ʻana i nā koʻokoʻo slender a me nā ʻāpana ʻāpana lahilahi. ʻO ka ʻoki ʻana i ka ʻili mīkini o ka rebound he nui loa, ma kahi o 2-3 mau manawa o ke kila kuhili ʻole, ka hopena i ka friction ʻoi, adhesion, a me ka hoʻopaʻa paʻa ʻana ma ke alo hope o ka mea hana.
