Indlela Yokwenza I-Dehydrogen Annealing Forgings: Umhlahlandlela Ophelele

I-hydrogen embrittlement iyinkinga ebalulekile ekukhiqizweni nasekulashweni kwangemuva kokwelashwa, ikakhulukazi lezo ezenziwe ngezinsimbi ezinamandla kakhulu, izinsimbi ezingenasici, nama-alloys e-titanium. Ukuba khona kwama-athomu e-hydrogen avaleleke esakhiweni sensimbi kungaholela ekuqhekekeni, ekunciphiseni i-ductility, kanye nokwehluleka okungalindelekile. Ukuqeda le ngozi,i-dehydrogen annealing-okwaziwa nangokuthi i-hydrogen relief annealing-iyinqubo eyinhloko yokwelapha ukushisa esetshenziselwa ukususa i-hydrogen emuncwe ekwenziweni.

Le ndatshana ye-SEO ebanzi ichaza inqubo ye-dehydrogen annealing ye-forging, ukubaluleka kwayo, izinqubo ezijwayelekile, amapharamitha, izinto ezisebenzayo, kanye nezindlela ezihamba phambili zomkhakha. Noma ngabe ungunjiniyela wokwelapha ukushisa, umthengi wezinto zokwakha, noma umhloli wekhwalithi, lo mhlahlandlela uzokusiza ukuthi uqonde ukuthi ungasebenzisa kanjani i-dehydrogen annealing ngempumelelo kuzilungiselelo zezimboni.

Iyini i-Dehydrogen Annealing?

I-Dehydrogen annealing iyi-ainqubo yokwelapha ukushisakwenziwe ukususai-hydrogen encibilikisiwekusuka ezingxenyeni ezibunjiwe. I-Hydrogen ingase yethulwe ngesikhathi:

• I-Pickling (ukuhlanza i-asidi)

• I-Electroplating

• Ukushisela

• Ukwakha endaweni enomswakama noma ene-hydrogen ecebile

Uma ingasusiwe, ama-athomu e-hydrogen angabangelaukuqhekeka okwenziwe nge-hydrogen(HIC), ukubambezeleka ukuqhekeka, nomaukulahlekelwa ubuqotho bemishini.

Inqubo ye-annealing ihilela ukushisa i-forging ekushiseni okulawulwayo-ngezansi kwephuzu lokuvuselela kabusha-futhi uyibambe isikhathi esithile ukuze uvumele i-hydrogen ukuba ihlakazeke ngaphandle kwe-lattice yensimbi.

Kungani I-Dehydrogen Annealing Ibalulekile?

Inqubo ibalulekile ngenxa yezizathu ezimbalwa:

• Ivimbela ukwehluleka kwe-hydrogen embrittlement

• Ibuyisela izakhiwo zemishini ezifana ne-ductility nokuqina

• Ithuthukisa ukwethembeka nokuphepha emsebenzini

• Ibalulekile ukuze kuhlangatshezwane nezindinganiso ze-aerospace, izimoto, kanye nekhwalithi yenuzi

Ezingxenyeni zamandla aphezulu njengamabhawudi, amagiya, ama-shaft, nezingxenye zesakhiwo, i-dehydrogen annealing iqinisekisa ukusebenza kwesikhathi eside futhi kunciphisa ingozi yokwehluleka okungalindelekile.

sakysteelinikeza ama-forging anesevisi yokuzikhethela ye-dehydrogen annealing yezimboni ezinezakhiwo eziqinile zemishini kanye nezidingo zokuphepha.

Izinto Ezidinga I-Dehydrogen Annealing

I-Dehydrogen annealing ivame ukusetshenziswa kulezi zinto ezilandelayo zomgunyathi:

• Izinsimbi zekhabhoni(ikakhulukazi ecishiwe futhi ethukuthele)

• Izinsimbi ze-alloy(isb, 4140, 4340, 1.6582)

• Izinsimbi ezingenasici ze-Martensitic(isb., 410, 420)

• Izinsimbi ezingenasici ze-Austenitic(isb, 304, 316 - ngemva kokukhetha noma ukucwenga)

• I-Titanium ne-titanium alloys

• Ama-alloys asekelwe ku-nickel(ezindaweni ezivezwe nge-hydrogen)

Ama-Forging adalulwe ekuhlanzeni okune-asidi, ukusabela kwe-electrochemical, noma umkhathi oqukethe i-hydrogen kungamakhandidethi ayinhloko alokhu kwelashwa.

I-Dehydrogen Annealing Procedure for Forgings

1. Ukuhlanza Ngaphambili

Ngaphambi kokufakwa kwe-anneal, ukubumba kufanele kuhlanzwe ku-oyela, ukungcola, noma izendlalelo ze-oxide ukuze kugwenywe ukungcoliswa ngesikhathi sokwelashwa kokushisa.

2. Ilayisha esithandweni somlilo

Izingxenye zilayishwa ngokucophelela esithandweni somlilo esihlanzekile, esomile esinokusakazwa komoya okuhle noma isivikelo somoya ongasebenzi uma kudingeka.

3. Isiteji Sokushisa

Ingxenye ishisa kancane kancane ekushiseni kwe-dehydrogenation. Izinga lokushisa elivamile lihlanganisa:

• Izinsimbi zensimbi: 200–300°C ngezinsimbi ezinamandla aphansi, 300–450°C ngezinsimbi zamandla aphezulu

• Izingxube ze-TitaniumUkushisa: 500-700°C

• Ama-alloys e-nickelUkushisa: 400–650°C

Ukushisa okusheshayo kugwenywe ukuvimbela ukucindezeleka okushisayo noma ukungqubuzana.

4. Isikhathi sokuphumula

I-forging ibanjwa ezingeni lokushisa eliqondiwe ukuze i-hydrogen isakazeke ngaphandle. Isikhathi sokucwilisa sincike kokuthi:

• Uhlobo lwezinto ezibonakalayo nobulukhuni

• Ukuqina kwezindonga kanye nejometri

• Izinga lokuchayeka kwe-hydrogen

Isikhathi sokucwilisa esijwayelekile:
Amahora ama-2 kuye kwangama-24.
Umthetho wesithupha: ihora elingu-1 iyintshi ngayinye yogqinsi, noma njengokujwayela okujwayelekile.

5. Ukupholisa

Ukupholisa kwenziwa kancane esithandweni noma emoyeni ukuze kugwenywe ukushaqeka okushisayo. Kuzinhlelo zokusebenza ezibucayi, ukupholisa igesi ye-inert kungase kusetshenziswe.

sakysteelisebenzisa izinga lokushisa elilinganiselwe, izithando zomlilo ezilungisekayo ezinezinqamuli ezinembile nezilawuli zesikhathi sokucwilisa ukuze kuqinisekiswe imiphumela engaguquki yokuhlanganisa i-dehydrogen.

Izinto Ezisetshenziswayo

• Amaqoqwana kagesi noma ngegesi

• I-atmosphere elawulwayo noma i-vacuum furnaces (ye-titanium/nickel alloys)

• Ama-thermocouples nezilawuli zokushisa

• Izinzwa zokuthola i-hydrogen (kuyakhetheka)

Amasistimu azenzakalelayo anokungena kwezinga lokushisa aqinisekisa ukulandeleka kwenqubo.
