ʻO ke kila kila ma ka Aerospace: nā waiwai a me nā pono

Ke koi nei ka ʻoihana aerospace i nā mea e hiki ai ke kū i nā wela wela, nā puʻe kiʻekiʻe, a me nā kaiapuni corrosive-ʻoiai e mālama ana i ka kūpaʻa a me ka hōʻemi ʻana i ke kaumaha. Ma waena o nā metala i hoʻohana ʻia i ka mokulele a me nā noi ākea,kila kohu ʻolepaʻa i kahi kūlana koʻikoʻi ma muli o kānake kaulike kū hoʻokahi o ka ikaika, ka pale ʻana i ka corrosion, a me ka formability.

Ma kēia ʻatikala, e ʻimi mākou i kanā waiwai a me nā pono o ke kila kila ma ka aerospace, kona mau noi maʻamau, a no ke aha e hoʻomau ai ka poʻe ʻenekinia e hilinaʻi iā ia no nā ʻōnaehana koʻikoʻi palekana. Hāʻawi ʻia esasaalloy, kou kumu hilinaʻi no ka hana kiʻekiʻe-hana kuhiliʻole kila hoʻohuihui 'enekinia no ka aerospace maikaʻi loa.

No ke aha i hoʻohana ʻia ai ke kila kila ma ka Aerospace

ʻO ke kila kila ka mea i hana mua ʻiahao, chromium (ka palena iki 10.5%), a me nā mea ʻē aʻe e like menickel, molybdenum, a me ka titanium. Hiki i kēia haku mele ke hana i ka meapapa hāmauʻo ia ka mea e pale ai mai ka oxidation a me ka corrosion, ʻoiai ma lalo o nā kūlana kūlohelohe koʻikoʻi.

No ka aerospace, hāʻawi ke kila kila i kahi hui like ʻole o kēia:

• Ka ikaika tensile kiʻekiʻe

• ʻO ke kū'ē i kaʻinoʻino a me ka wela

• ʻO ka luhi a me ke kūpaʻa kolo

• Hiki ke hana a me ka weldability

• Ke ahi a me ka oxidation pale

Hana kēia mau waiwai i ke kila kila i koho maikaʻi loa no ka hoʻolālā aerospace a me nā noi ʻole.

ʻO nā waiwai kila kila ma ka Aerospace

1. Ka ikaika a me ka lōʻihi o ka mīkini

Loaʻa nā ʻāpana mokulele i nā pōʻai pinepine o ke kaumaha a me ka haʻalulu. Kiʻekiʻe ke kila kilahāʻawi i ka ikaika a me ka pale ʻana i ka luhie hana i mea kūpono no ka lawe ʻana i ka ukana e like me ka pae pae ʻana, nā ʻāpana ʻenekini, a me nā mea paʻa.

2. Pale ʻino

Ma nā kiʻekiʻe kiʻekiʻe a ma kahi ākea, ke alo nā meaka mākū, ka wai hoʻoheheʻe, ka ea paʻakai, a me nā mea kemika ʻinoʻino. Paʻa loa ke kila kila i ka corrosion maʻamau a kūloko (pitting a crevice), e hōʻoiaʻiʻo aihilinaʻi lōʻihi.

3. Kū'ē Kūlana Kiʻekiʻe

Hoʻopuka nā mīkini jet a me nā noi hypersonicwela loa. ʻO nā kila kila Austenitic, e like me304, 316, a me 321, mālama i ka ikaika a me ka pale ʻana i ka oxidation ma luna o 600°C. Nā māka paʻakikī e like me ka ua17-4PHhana maikaʻi loa ma lalo o ka wela a me ke kaumaha.

4. Formability a me ka hana

He mea maʻalahi ke kila kilamīkini, wili ʻia, a hana ʻia, e ʻae ana i nā ʻano paʻakikī a me nā hoʻolālā maʻamau. He mea koʻikoʻi kēia i ka aerospace, kahi e hoʻokō ai nā ʻāpana i nā hoʻomanawanui paʻa a me nā kūlana hana.

5. Kū'ē ahi a me nā kolo

'A'ole e like me ka nui o nā alale'a māmā, hiki i ke kila kuhili ke kū'ē i ka deformation (creep) a mālama i ka ikaikama lalo o ka loaʻa ʻana o ka wela lōʻihi, kūpono ia no nā ʻāpana koʻikoʻi ahi.

Nā Papa Kūleʻa Kūleʻa maʻamau ma Aerospace

Nui nā māka kila kila i makemake ʻia i ka aerospace no kā lākou ʻano hana kikoʻī:

• 304/316: Ke kū'ē i ka corrosion maʻamau, hoʻohana ʻia i loko a me nā ʻāpana haʻahaʻa haʻahaʻa

• 321: Hoʻopaʻa ʻia me ka titanium e pale aku i ka corrosion intergranular i nā wela kiʻekiʻe

• 347: E like me 321 akā hoʻopaʻa ʻia me ka niobium

• 17-4PH (AISI 630): Ke kila kuhiliʻole paʻa i ka ua me ka ikaika kiʻekiʻe a me ke kūpaʻa maikaʻi loa

• 15-5PH: Kokoke ikaika kiʻekiʻe i ka 17-4PH me ka ʻoi aku ka paʻakikī

• A286: Iron-nickel-chromium alloy me ka maikaʻi o ka pale ʻana a hiki i 700°C

At sasaalloy, Hoʻopaʻa a hoʻolako mākou i nā māka kila kila kila i ʻae ʻia aerospace me ka traceability piha a me ka hōʻoia no nā noi koʻikoʻi.

Noi o ka Aerospace o ke kila kila

1. Nā mea ʻenekinia

Hoʻohana ʻia ke kila kila ma:

• ʻO nā lau huila turbine

• Keena puhi

• Nā ʻauwaha hoʻopau

• ʻO nā sila a me nā pale wela

Ke hana nei kēia mau ʻāpana ma lalo o ka wela nui a me ke kaomi, e pono ai ka pale wela a me ka luhi o ke kila kila.

2. Nā ʻāpana mokulele a me nā ʻāpana

• Lae pae

• Paipu wai hydraulic

• Nā pale a me nā papa kākoʻo

ʻO ka hui pū ʻana o ke kila kila me ka ikaika a me ka hopena e hoʻonui ai i ka palekana i ka wā o ka lele ʻana, ka lele, a me ka pae ʻana.

3. Nā Paʻa a me nā Puna

ʻO nā mea hoʻopaʻa kila kila e mālama i ka pono ma lalo o ke kaumaha a me ka hoʻololi ʻana i ka mahana, ʻoiai nā pūnāwai i hana ʻia mai ke kila kilaelasticity mau loaa me ka pale ʻana i ka corrosion.

4. Huina a me Hydraulic System

Ma muli o kona kūpaʻa kemika, hoʻohana ʻia ke kila kila ma:

• Nā pahu pahu a me nā paipu

• Nā laina hydraulic

• Nā mea hoʻohui a me nā kiwi

Pono e hana pono kēia mau ʻāpana ma lalo o ke kaomi a me ka ʻike kemika.

5. Keena a me na mea o loko

Hoʻohana ʻia ke kila kila i loko o nā panela, nā papa noho, nā papa pākaukau, a me nā galleys noka maʻemaʻe, ka palekana ahi, a me ka hoʻopiʻi nani.

ʻO nā pono o ke kila kila ma ka Aerospace

• Paʻa pono: Kū i ke koʻikoʻi mechanical, thermal, a me kemika

• Ka lōʻihi: Paʻa a me ka corrosion i nā kūlana koi

• Hoʻonui kaumaha: ʻOiai ʻoi aku ke kaumaha ma mua o ka alumini a i ʻole ka titanium, hiki i nā māka kulika ikaika kiʻekiʻe ke ʻae i nā hoʻolālā ʻoi aku ka lahilahi a māmā.

• Palekana ahi: ʻAʻole ʻā a hoʻolaha paha i nā lapalapa, pono no ka palekana o ka hale

• Hoʻohana hou: He 100% hiki ke hana hou ke kila kila, e kākoʻo ana i nā hana aerospace hoʻomau

ʻO kēia mau pōmaikaʻi e hana i ke kila kila amea hilinaʻi i kēlā me kēia hanauna o ka hoʻolālā mokulele.

ʻO ka wā e hiki mai ana o ke kila kila ma ka Aerospace

Ke ulu nei ka ʻenehana aerospace—ʻoi loa me ka piʻi ʻana omākaʻikaʻi lewa, mokulele uila, ahuakaʻi hypersonic—ua manaʻo ʻia e hoʻonui ʻia ka hana o ke kila kila. Ke ulu nei nā ʻenekinianā mea hoʻoheheʻe kuhili ka hanauna houme ka hoʻomaikaʻi ʻana i ke kūpaʻa creep, weldability, a me ka ikaika-a-kaumaha ratios e hālāwai ai i kēia mau pilikia e hiki mai ana.

At sasaalloy, hana pū mākou me nā mea hana aerospace a me nā hui R&D e hoʻolakonā hāʻina kuhili ʻoleno nā ʻenehana aerospace kuʻuna a me nā ʻenehana hou aʻe.

Ka hopena

Mai nā turbine kiʻekiʻe a hiki i ka hoʻopau o loko,ʻo ke kila kila he mea pōhaku kihii ka ʻoihana aerospace. ʻO kāna hui like ʻole o ka ikaika mechanical, ka pale ʻana i ka wela, a me ka paʻa ʻana o ka corrosion e hōʻoia i ka palekana, ka pono, a me ka hana ma kēlā me kēia kiʻekiʻe.

Inā makemake ʻoe i nā ʻāpana kulika aerospace-grade, nā koʻokoʻo, nā paipu, a i ʻole nā ​​mea paʻa,sasaalloyhāʻawi i nā mea hana pololei i kākoʻo ʻia e nā palapala hōʻoia a me ke kākoʻo ʻenehana loea. hilinaisasaalloye mālama i kāu papahana aerospace e lele kiʻekiʻe—me ka palekana, hilinaʻi, a me ka maikaʻi.
