Iyo abajenjeri bagaragaje ibice bya cobalt bivangwa na pompe ya hydraulic, pompe ya peteroli, cyangwa sisitemu yo kwambara cyane, ntabwo bagura ibyuma gusa-bagura ituze ryikigereranyo munsi ya 300 ° C yumukino wo gusiganwa ku maguru, kurwanya imbaraga zo gutembera ahantu habi cyane, hamwe na microstructural guhuza kuri byinshi nyuma yubufindo. Niyo mpamvu "6 cobalt alloy part uruganda" ntabwo ari interuro yo kwamamaza-ni urwego rukora. Batandatu ntabwo ari uko bishakiye. Irerekana umubare ntarengwa wubugenzuzi, busubirwamo bugenzurwa bukenewe kugirango ukemure AMS 5387, T800, nizindi superalloys ya cobalt-nikel itabangamiye ubusugire bwimbibi cyangwa ubuso burangiye. Twabonye abakiriya bahindura abatanga ibicuruzwa nyuma yibice bitatu byananiranye-buri gihe bashinja ibyemezo byibikoresho, gusa twabonye ko icyuho nyacyo kitari gihagije cyo kugenzura itanura ryikirere mugihe cyo gukemura.
Impamvu Amarembo atandatu asobanura amacakubiri ya Cobalt
Amavuta ya Cobalt ntabwo akora imashini nkicyuma kitagira umwanda. Bakora-bikabije, bitwara ubushyuhe nabi, kandi basaba ingamba zo gukoresha ibikoresho bingana no kwimura chip hamwe nubuyobozi bwumuriro. Uruganda 6 rwa cobalt alloy part part ntabwo rufite imashini za CNC gusa-rufite amarembo atandatu afitanye isano:
- Ibikoresho bikurikirana kugirango bishonge- nta kirango rusange “ASTM F75”; raporo yikizamini cyuzuye hamwe na ogisijeni / azote isigara yinjiye
- Mbere yo gutunganya imihangayiko-Gutegekwa gusaza kabiri mbere yo gukomera, ntabwo ari ubushake
- Inzira yihariye yo gukata ibipimo-Ntibigena, ariko byemewe / ibiryo byemewe / umuvuduko kuri buri cyiciro cya geometrie (urugero: uruzitiro ruto-rukuta ruvanze n'amacomeka akomeye)
- Muri gahunda yo kugenzura CMM kuri sitasiyo eshatu zasobanuwe- ntabwo ari ubugenzuzi bwa nyuma
- Kwemeza ubusugire-Koresha interferometrie yera-yoroheje, ntabwo ibipimo bya Ra gusa
- Ikizamini cyimikorere kubakiriya-bigereranijwe byinshingano- kanda ku magare, gupakira umuriro, cyangwa isuri mbere yo koherezwa
Kubura irembo rimwe, uzabona ibice bitambutsa igenzura ariko bikananirana kuri 12,000 PSI nyuma ya cycle 400. Twapimye ibisigisigi bya tensile bisigaye bigera kuri +420 MPa mubice bya cobalt byakozwe nta gutabarwa neza mbere yo guhangayika-bihagije kugirango imbuto za microcracks zitagaragara kuri NDT zisanzwe.
Aho Gukora bisanzwe-Gukora Imashini Zimeneka
Amaduka amwe abanza guta, hanyuma imashini. Abandi imashini. Ntanubwo ikora neza kububiko bwa pompe ya cobalt isaba ± 0,015 mm kwibanda hagati ya bore na flange. Kubera iki? Kuberako cobalt yo kwagura ubushyuhe bwa cobalt ihinduranya 12% hagati ya as-cast na leta zivura ubushyuhe-kandi kugabanuka kumusenyi biratandukana na 0.8-1.3% bitewe nubucucike bwibumba. Gukosora ntabwo kwihanganira gukomera. Ni uburyo bwo guhuza ibikorwa: gushora imari hafi ya net hamwe na 0.5 mm yo gutunganya imashini, hanyuma bigakurikirwa no kugabanya imihangayiko annealing * mbere yuko * gukuramo ibyuma bitangira. Noneho, imirongo myinshi ihinduranya hamwe nibikoresho bizima kugirango ufate ID / OD coaxiality muri mm 0.008 - ntabwo ari ukubera ko imashini isobanutse neza, ahubwo ni ukubera ko moderi ya drift yubushyuhe ihindurwamo kuri lisansi yihariye. Nibyo guhuza vertical urashobora gupima-ntabwo ari isoko.
Imikorere nyayo-Isi: Ntabwo ari Impamyabumenyi gusa
Pompe imwe yo muri Amerika y'Amajyaruguru OEM yatangaje ko 22% byananiranye hakiri kare muri cobalt alloy nozzles yaturutse ku mucuruzi avuga ko "ISO 9001 yubahirije." Impamvu? Microcrack yubuso yatangijwe mugihe cyo kurambirwa kudashyigikiwe-bigaragara munsi ya 200x SEM. Ubutaha bwabo, QINGDAO QIANGSENYUAN TECHNOLOGY CO., LTD., Yashyizemo uburinganire bwa ultrasonic busikana mu irembo ryayo rya nyuma. Igisubizo: kunanirwa kwa zeru mu mezi 18 muri 37 offshore. Nta bupfumu. Gusa wanditse disipuline yuburyo butandatu-harimo kugenzura ibikoresho fatizo kuri AMS 2269 kubintu bya ogisijeni, bigenga mu buryo butaziguye amarira ashyushye muri T800.
Abakiriya ntibabaza "Ukora ibice bya cobalt?" Barabaza bati: "Urashobora gufata 0.005 mm yiruka kumashanyarazi ya mm 120 ya cobalt mugihe ukomeje gukomera kuri HR22?" Ibyo byihariye bitandukanya laboratoire ninganda. Irasobanura kandi impamvu amakipi yubuhanga mubudage na Singapuru ubu yerekeza GD & T-ibishushanyo biremereye yerekeza i Qingdao - ntabwo ari ikiguzi, ahubwo nibitekerezo byatanzwe kubicuruzwa ku mpande zombi, munsi, hamwe n’amafaranga yo kugoreka ubushyuhe mbere yo gutangira ibikoresho.
Guhitamo Ibikurikira Cobalt Alloy Umufatanyabikorwa: Amasheki atatu Atari Umushyikirano
Mbere yo gushyira umukono kuri RFQ, genzura ibi - bitari mu gatabo, ahubwo byanditswe mu bicuruzwa:
- Baza raporo eshatu zanyuma za CMM kuri cobalt alloy igice gihuye na geometrie yawe- ntabwo ari impuzandengo, ariko gutandukana kwukuri, harimo ibiti by'ubushyuhe mugihe cyo gupima
- Saba ibicanwa by'ibicanwa biturutse kuri AMS 5387 yanyuma yo kuvura ubushyuhe—Oxygene ppm igomba kuguma munsi ya 25 mugihe cyo gukemura igisubizo kugirango wirinde kwinjiza sigma
- Emeza niba kurangiza kwabo birimo amashanyarazi cyangwa gukanika imashini—Electro ikuraho ibyangiritse kubutaka; gukubita bitera guhangayika ariko birashobora kuzenguruka impande zose
Ikimenyetso gikomeye ntabwo ari ibyemezo. Nuburyo bakwereka vuba amakuru-ntabwo ari icyemezo, ahubwo nimibare iri inyuma yacyo. Kuberako muri cobalt alloy porogaramu, icyubahiro kimara kugeza kumwanya wambere watsinzwe. Imikorere ikomeza kugeza kumurongo wanyuma.
