Marka injineeradu u cayimaan qaybaha daawaynta cobalt ee bambooyinka hawo-qaadista, valves oilfield, ama nidaamka winch-ga-gabista, kaliya maaha inay iibsadaan biraha - waxay iibsanayaan xasilloonida cabbirka ee ka hooseeya 300 ° C baaskiil kuleyl ah, iska caabin xammeetida jawiyada qulqulaya, iyo joogteynta qaab-dhismeedka qaab-dhismeedka yar yar kadib wax badan. Taasi waa sababta "6 warshadda qayb ka mid ah cobalt alloy" ma aha odhaah suuq-geyneed - waa marin hawleed. Lix ma aha gardarro. Waxay ka tarjumaysaa tirada ugu yar ee la xaqiijiyay, kontaroolada habka dib loo celin karo ee loo baahan yahay si loo maareeyo AMS 5387, T800, iyo cobalt-nickel superalloys iyada oo aan wax u dhimayn hufnaanta xadka hadhuudhka ama soo noqnoqoshada dusha sare. Waxaan aragnay macaamiishu beddelaadda alaab-qeybiyeyaasha ka dib saddex qaybood oo guul-darraystay - mar kasta oo ay ku eedaynayaan shahaado shahaado, kaliya in la ogaado cidhiidhiga dhabta ah ee dhabta ahi wuxuu ahaa mid aan ku filnayn xakamaynta jawiga foornada inta lagu jiro xalinta.
Waa maxay Sababta Lixda Hab-raac ee Albaabka ay u qeexaan isku hallaynta Alloy Cobalt
Alaabooyinka Cobalt uma shaqeeyaan sida birta aan lahayn. Waxay u shaqeeyaan si adag, waxay u dhaqmaan kuleyl si liidata, waxayna dalbadaan xeelado qalabayn oo dheellitiran daadgureynta dabka iyo maamulka kulaylka. Warshada qayb ka mid ah daawaynta cobalt ee 6 run ma aha kaliya mashiinada CNC-waxay leedahay lix albaab oo isku xidhan:
- Raadinta walxaha hoos u dhalaalaysa dufcada-ma laha calaamado guud "ASTM F75"; Warbixinnada tijaabada shiidalka buuxa oo ay ku jiraan hadhaaga oksijiinta/nitrojiinka la galiyay
- Mashiinka ka-hortagga cadaadiskaLaba-gabowga qasabka ah ka hor inta aan qalafsaneyn, ma aha ikhtiyaari
- Calaamadaha goynta gaarka ah ee dariiqa aalada-ma aha kuwa hore loo dejiyay, balse si macquul ah loo ansaxiyay quudinta/xawaaraha fasalkiiba joomatari (tusaale, dhufaysyada gidaarka khafiifka ah iyo kuwa adag)
- Xaqiijinta CMM ee hawsha ku jirta ee saddex saldhig oo qeexan-ma aha kaliya kormeerka ugu dambeeya
- Xaqiijinta daacadnimada dusha sare-Isticmaalka interferometry-iftiin cad, ma aha oo kaliya cabbirada Ra
- Tijaabada shaqaynaysa ee wareegyada shaqada ee la mid ah macmiilka— cadaadis baaskiil, rarista qulqulka, ama soo-gaadhista nabaad-guurka ka hor inta aan la rarin
Hal albaab seeg, oo waxaad heli doontaa qaybo ka gudba jeegaga cabbirka laakiin ku guul darraystay 12,000 PSI 400 wareeg ka dib. Waxaan cabbirnay haraaga culeyska culeyska ilaa +420 MPa ee qaybaha cobalt-ka ee lagu farsameeyay iyada oo aan la helin gargaar ku habboon walaaca kahor-ku filan abuur mikrocracks aan la arki karin heerka NDT.
Halka ay socodka shaqadu ka burburto Heerka Casting-Machining
Dukaamada qaar ayaa marka hore tuuraya, ka dibna mishiinada. Qaar kale oo biisha mashiinka ah. Midkoodna si la isku halayn karo uguma shaqeeyo guryaynta matoorka daawaha ee u baahan ± 0.015 mm xooga saarista inta u dhaxaysa wejiga dhadhaarka iyo baallaha. Waa maxay sababtu? Sababtoo ah iskudarka balaadhinta kulaylka ee cobalt waxay u beddeshaa 12% inta u dhaxaysa sida-cast-ka iyo dawladaha kulaylka lagu daweeyay-iyo tuurista ciiddu way kala duwan tahay 0.8-1.3% iyadoo ku xidhan cufnaanta caaryada. Hagaajintu maaha dulqaad adag. Waa isku dhafka habka isku-dhafka ah: maalgelinta ku shubista qaabka dhow oo leh gunnada mashiinka 0.5 mm, oo ay ku xigto baabi'in-dejinta * ka hor * ka saarista birta ah ee kasta. Kadibna, dhidibo badan oo u rogaya qalab toos ah si loo qabto ID/OD isku xidhka gudaha 0.008 mm -ma aha sababtoo ah mashiinku waa sax, laakiin sababta oo ah moodeelka kuleylka kuleylka ayaa lagu qiimeeyay wax badan oo alloy ah. Taasi waa isdhexgalka toosan oo aad cabbiri karto-ma aha suuq.
Waxqabadka dhabta ah ee aduunka: Ma aha oo kaliya Shahaadooyinka
Mid ka mid ah bamka OEM ee Waqooyiga Ameerika ayaa soo sheegay 22% fashilaad degdeg ah oo ku yimid nozzles alloy cobalt oo ka yimid iibiye sheeganaya "u hoggaansanaan buuxda ISO 9001." Sababta xididka ah? Microcracks dusha sare waxa la bilaabay inta lagu guda jiro hawlgalada caajiska ah ee aan la taageerin-ka muuqda oo ka hooseeya 200x SEM. Alaab-qeybiyaha xiga, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Ku dhejisan iskaanka hufnaanta dusha sare ee ultrasonic galay albaabkiisa ugu dambeeya ee QC. Natiijadu: eber nozzles ku guuldareystay muddo 18 bilood ah 37 riigagga badda. Sixir ma jiro. Waxa kaliya oo la diiwaangeliyay nidaamka edbinta ee dhammaan lixda irdood - oo ay ku jirto xaqiijinta alaabta ceeriin ee ka dhanka ah AMS 2269 ee nuxurka oksijiinta, taas oo si toos ah u maamusha u nuglaanta jeexjeexa kulul ee tuurista T800.
Macaamiishu ma waydiiyaan "Ma samaysaa qaybo cobalt ah?" Waxay ku weydiinayaan "Ma ku hayn kartaa 0.005 mm dareere ka soo dareere ah 120 mm dhexroorka koronto adigoo ilaalinaya ≤22 adkaanta dusha sare ee HRC?" Tilmaamahaas ayaa kala saaraya shaybaadhka iyo warshadaha. Waxayna sharraxaysaa sababta kooxaha injineerada ee Jarmalka iyo Singapore ay hadda u mareen GD&T-sawirro culus si toos ah Qingdao-ma aha kharash, laakiin falcelinta wax soo saarka ee xaglaha qabyada ah, goynta, iyo gunnada qalloocinta kulaylka-daweynta ka hor inta aan qalabayntu bilaaban.
Doorashada Saaxiibkaaga Xiga ee Daawaha Cobalt: Saddex jeeg oo aan gorgortan lahayn
Kahor intaadan saxiixin RFQ, xaqiiji kuwan-ma aha buug-yaraha, laakiin ku jira diiwaannada wax soo saarka:
- Weydiiso saddexdii warbixin ee CMM ee u dambeeyay qayb daawaha cobalt ah oo ku habboon joomatarigaaga-ma aha celcelis ahaan, laakiin leexashada daabacaadda dhabta ah, oo ay ku jiraan diiwaannada heerkulka inta lagu jiro cabbirka
- Codso jaantusyada jawiga foornada laga soo bilaabo AMS 5387 wareegga daawaynta kulaylka ee u dambeeyayOgsajiin ppm waa in ay ka hooseyso 25 inta lagu jiro soo saarista xalalka si looga hortago qallafsanaanta wajiga sigma
- Xaqiiji in dhammayntooda ay ku jirto jeexid koronto-dhal ah ama farsamayn-electro waxay ka saartaa burburka dhulka hoostiisa; Laabashadu waxay keentaa diiqad cadaadis leh laakiin waxay halis u tahay in la soo wareego cidhifyada cabbiraadda fiiqan
Digniinta ugu xooggani maaha shahaadooyin. Waa sida ugu dhakhsaha badan ee ay kuugu tusinayaan xogta - maaha shahaadada, laakiin lambarrada ka dambeeya. Sababtoo ah codsiyada daawaha cobalt, sumcaddu waxay sii socotaa ilaa guuldarada ugu horeysa ee goobta. Waxqabadku wuxuu socdaa ilaa wareegga u dambeeya.
