chidziwitso

Gr5 Ti6Al4V waya wa titaniyamu ndi zinthu zamphamvu kwambiri, zocheperako zomwe zimagwiritsidwa ntchito kwambiri muzamlengalenga, zamankhwala, ndi mafakitale. Mphamvu yake yokhazikika ndi chinthu chofunikira kwambiri chomwe chimatsimikizira momwe amagwirira ntchito m'malo osiyanasiyana ovuta. Cholemba chabuloguchi chiwunika kulimba kwa waya wa titaniyamu wa Gr5 Ti6Al4V ndikuyankha mafunso okhudzana ndi izi kuti timvetsetse bwino zinthu zochititsa chidwizi.

Kodi kulimba kwamphamvu kwa Ti6Al4V kumafananiza bwanji ndi ma aloyi ena a titaniyamu?

Ti6Al4V, yomwe imadziwikanso kuti Gr5 Ti6Al4V waya wa titaniyamu, ndi imodzi mwazitsulo zomwe zimagwiritsidwa ntchito kwambiri ndi titaniyamu chifukwa cha kuphatikiza kwake kwamphamvu, kulimba, komanso kukana dzimbiri. Poyerekeza mphamvu ya Ti6Al4V ya TiXNUMXAlXNUMXV ndi ma aloyi ena a titaniyamu, ndikofunikira kuganizira zinthu zosiyanasiyana zomwe zimakhudza makina, monga kutentha, njira zopangira, ndi mawonekedwe azinthu (mwachitsanzo, waya, pepala, kapena bala).

Nthawi zambiri, Ti6Al4V imawonetsa kulimba kwamphamvu kwambiri poyerekeza ndi magiredi abwino a titaniyamu (Makalasi 1-4). Mphamvu yokhazikika ya Ti6Al4V yokhazikika imayambira 895 mpaka 1000 MPa (130 mpaka 145 ksi). Poyerekeza, giredi 4 ya titaniyamu yoyera pazamalonda, yomwe ndi yamphamvu kwambiri pamakalasi osatulutsidwa, ili ndi mphamvu zolimba pafupifupi 550 MPa (80 ksi).

Poyerekeza ndi ma aloyi ena a titaniyamu, Ti6Al4V nthawi zambiri imagwera pakatikati pamitengo yamphamvu yamphamvu. Mwachitsanzo:

• Ti-3Al-2.5V (Giredi 9) ili ndi mphamvu yocheperako, nthawi zambiri imazungulira 620-730 MPa (90-106 ksi).
• Ti-6Al-2Sn-4Zr-6Mo (Ti6246) ili ndi mphamvu zowonjezereka, nthawi zambiri zimaposa 1100 MPa (160 ksi).
• Ti-10V-2Fe-3Al (Ti10-2-3) ikhoza kukwaniritsa mphamvu zowonjezereka zowonjezereka, mpaka 1380 MPa (200 ksi) kapena kuposa, malingana ndi chithandizo cha kutentha.

Ndizofunikira kudziwa kuti mphamvu zamakokedwe za Ti6Al4V zitha kuchulukitsidwa kwambiri ndi chithandizo cha kutentha ndi kukonza. Mwachitsanzo, yothandizidwa ndi okalamba (STA) Ti6Al4V imatha kufikira mphamvu zolimba mpaka 1100-1300 MPa (160-190 ksi). Kuonjezera apo, Ti6Al4V ikasinthidwa kukhala mawonekedwe a waya, kuzizira komwe kumagwiritsidwa ntchito pojambula waya kungathe kuonjezera mphamvu zake, zomwe zingathe kufika pamtengo wa 1500 MPa (218 ksi) kapena kupitilira apo, kutengera kukula kwa waya ndi momwe zimapangidwira.

Ndi zinthu ziti zomwe zimakhudza kulimba kwa waya wa Ti6Al4V titaniyamu?

Mphamvu yamanjenje ya Gr5 Ti6Al4V waya wa titaniyamu imakhudzidwa ndi zinthu zingapo, chilichonse chimagwira ntchito yofunika kwambiri pakuzindikira mawonekedwe omaliza azinthuzo. Kumvetsetsa zinthu izi ndikofunikira kwa mainjiniya ndi opanga omwe amagwira ntchito ndi alloy iyi kuti akwaniritse bwino ntchito zake pazantchito zina.

1. Chithandizo cha Kutentha: Njira yochizira kutentha imakhudza kwambiri microstructure ndipo, motero, mphamvu yowonongeka ya Ti6Al4V. Thandizo lodziwika bwino la kutentha limaphatikizapo:

• Annealing: Izi zimachepetsa kupsinjika kwamkati ndikuwongolera ductility koma zimatha kuchepetsa mphamvu zolimba.
• Kuthetsa Kuchiza ndi Kukalamba (STA): Njira ziwirizi zitha kuwonjezera mphamvu zolimba popanga gawo labwino, lobalalika mkati mwa microstructure.
• Beta Annealing: Chithandizo chotentha kwambiri chotsatiridwa ndi kuziziritsa pang'onopang'ono kumatha kupangitsa kuti pakhale mawonekedwe apadera omwe amalinganiza mphamvu ndi ductility.

2. Cold Working: Njira yojambulira waya imayambitsa ntchito yozizira muzinthu, zomwe zimatha kuwonjezera mphamvu zake zolimba. Kuchuluka kwa magwiridwe antchito ozizira, omwe amawonetsedwa ngati kuchuluka kwa kuchepetsa madera, kumagwirizana mwachindunji ndi kuwonjezereka kwamphamvu kwamphamvu. Komabe, kugwira ntchito kozizira kwambiri kungayambitse kuchepetsedwa kwa ductility komanso brittleness.

3. Waya Diameter: Nthawi zambiri, momwe waya wakuya ukucheperachepera, mphamvu yamanjenje imawonjezeka. Izi zimachitika chifukwa cha kuchuluka kwa ntchito yozizira yomwe imayenera kupanga mawaya ang'onoang'ono ang'onoang'ono komanso kukula kwa zinthu zakuthupi.

4. Kukula kwa Mbewu ndi Kuyikira kwake: Kukula kwambewu zocheperako nthawi zambiri kumapangitsa kuti pakhale kulimba kwamphamvu chifukwa cha kuchuluka kwa malire ambewu zomwe zimalepheretsa kusuntha kwapang'onopang'ono. Mayendedwe a njerezi (mawonekedwe) amathanso kukhudza mphamvu yamphamvu, makamaka mu mawaya okokedwa pomwe njere zimakonda kugwirizanitsa pojambula.

5. Kusiyanasiyana kwa Mapangidwe: Ngakhale kuti Ti6Al4V ili ndi kamangidwe kake, kusiyana kochepa mkati mwazovomerezeka kungakhudze mphamvu yake yokhazikika. Mwachitsanzo, kukwera pang'ono kwa okosijeni kumatha kubweretsa mphamvu zambiri koma kumachepetsa ductility.

6. Kutentha kwa Kutentha: Kutentha komwe waya amakonzedwa kungathe kukhudza zotsatira zake zomaliza. Kutentha kokwera kwambiri kungayambitse kukula kwa tirigu ndi kuchepetsa mphamvu, pamene kutentha kochepa kungapangitse mphamvu koma kumayambitsa zovuta.

7. Pamwamba Pamwamba: Ubwino wa pamwamba pa waya, kuphatikizapo kukhalapo kwa zolakwika kapena oxidation, zingakhudze mphamvu zake zowonongeka. Malo osalala, opanda chilema nthawi zambiri amapangitsa kuti pakhale nyonga zapamwamba komanso zosasinthasintha.

Poyang'anira zinthu izi mosamala, opanga amatha kusintha mphamvu yolimba ya waya wa titaniyamu ya Ti6Al4V kuti ikwaniritse zofunikira zenizeni, kaya ndi zomangira zamlengalenga, zoyikapo zachipatala, kapena akasupe ochita bwino kwambiri.

Kodi mawaya amphamvu kwambiri a Ti6Al4V a titaniyamu ndi ati?

Mkulu-mphamvu Gr5 Ti6Al4V waya wa titaniyamu imapeza ntchito zambiri m'mafakitale osiyanasiyana chifukwa cha kuphatikiza kwake kwamphamvu, mawonekedwe opepuka, komanso kukana dzimbiri. Kusinthasintha kwazinthu izi kumapangitsa kukhala chisankho choyenera kwa malo ovuta komanso kugwiritsa ntchito zovuta.

4. Ntchito Zam'madzi:

• Zosakaniza Zolimbana ndi Kuwonongeka: Waya wa Ti6Al4V umagwiritsidwa ntchito popanga zomangira ndi zomangira zamadzi am'madzi momwe kukana kwa dzimbiri ndikofunikira.
• Ma robotiki Apansi pa Madzi: Mphamvu ndi kukana kwa dzimbiri kwa Ti6Al4V kumapangitsa kuti ikhale yoyenera zigawo zamaloboti apansi pamadzi ndi zida zofufuzira.

5. Masewera ndi Zosangalatsa:

• Kulankhula Panjinga: Ma njinga apamwamba amatha kugwiritsa ntchito ma waya a Ti6Al4V ngati mphamvu zawo komanso katundu wochepetsa thupi.
• Zida Zophera Usodzi: Waya wa Titaniyamu amagwiritsidwa ntchito popha nsomba ndi zida zotsogola chifukwa cha mphamvu zake komanso kukana dzimbiri m'malo amchere amchere.

6. Ntchito Zamakampani:

• Chemical Processing: Waya wa Ti6Al4V umagwiritsidwa ntchito popanga zida zopangira mankhwala chifukwa cha kukana kwa dzimbiri.
• Makampani a Mafuta ndi Gasi: Kulimba kwazinthu komanso kukana malo ovuta kumapangitsa kuti zikhale zoyenera pazida zosiyanasiyana zapansi ndi zigawo.

7. Zodzikongoletsera ndi Ntchito Zokongoletsa:

• Zodzikongoletsera Pathupi: Kugwirizana kwachilengedwe ndi mphamvu ya Ti6Al4V imapangitsa kuti ikhale yotchuka pazodzikongoletsera zoboola thupi.
• Ntchito Yokongoletsa Wawaya: Ojambula ndi amisiri atha kugwiritsa ntchito waya wa Ti6Al4V pazinthu zake zapadera popanga ziboliboli zolimba, zopepuka komanso zodzikongoletsera.

8. Kafukufuku ndi Chitukuko:

• Sayansi Yazinthu: Waya wa Ti6Al4V nthawi zambiri amagwiritsidwa ntchito pofufuza kuti aphunzire zakuthupi ndikupanga mapulogalamu atsopano.
• Kupanga Zowonjezera: Munjira zopangira mawaya, waya wa Ti6Al4V umagwira ntchito ngati chakudya chopangira zida zosindikizidwa za 3D.

Mkulu wamakomedwe mphamvu ya Gr5 Ti6Al4V waya wa titaniyamu, kuphatikizika ndi kukana kwambiri kwa dzimbiri ndi biocompatibility, kumapangitsa kukhala chinthu chamtengo wapatali pamagwiritsidwe osiyanasiyana awa. Pamene njira zopangira zikupitirizabe kusintha ndipo ntchito zatsopano zikutuluka, kugwiritsa ntchito waya wa titaniyamu wa Ti6Al4V wamphamvu kwambiri akuyenera kukulirakulira, makamaka m'madera omwe ntchito zapamwamba ndi zodalirika ndizofunikira kwambiri.

Ku SHAANXI CXMET TECHNOLOGY CO., LTD, timanyadira zamitundu yathu yayikulu, yomwe imathandizira zosowa zosiyanasiyana zamakasitomala. Kampani yathu ili ndi luso lapadera lopanga ndi kukonza, kuwonetsetsa kuti zinthu zathu ndi zapamwamba komanso zolondola.
