Cobalt alloys haakotamira kukuda-ivo vanotsanangura. Kana pombi dze hydraulic dzichimhanya pa400 bar, kana mavharuvhu ekudzika akatarisana ne250 ° C uye H₂S, kana mawinch shafts paanotora akadzokororwa kuvhunduka mumotokari dzeinjiniya dzeArctic, kuneta kwemidziyo. Kukundikana hakusi zvishoma nezvishoma; dzinokurumidza, dzinodhura, uye dzakakosha-chinangwa. Takaona matatu AMS 5387 cobalt alloy pombi dzimba dzakaputika mukati me800 maawa ekushanda-kwete kubva pakukanganisa kwekugadzira, asi kubva pakusapindirana kwekupisa mukupisa batch. Ndicho chikonzero "6 cobalt alloy chikamu" haisi chete izwi rekutsvaga. Iyo yakasarudzika mapfupi mainjiniya anoshandisa kana dimensional kugadzikana, microstructural kufanana, uye kupfeka kuramba hazvigone kukanganisa.
Sei Nhanhatu-Kwete Imwe, Kwete Gumi-Cobalt Alloy Zvikamu Zvichipa Kuvimbika Kwechokwadi-Nyika
Chikwata chedu chakagadzira, chakayedza, uye chakasimbisa-mumunda-zvinopfuura zviuru gumi nezvinomwe zvecobalt-nickel zvikamu kubva muna 2018-kunyanya AMS 5387 uye T800 mamakisi-kune vatengi mumasevhisi emafuta, marine hydraulics, uye yakakwirira-kumanikidza bvunzo rigs. Hatina kusvika pazvitanhatu zvakakosha configuration netsaona. Imwe neimwe inogadzirisa yakasarudzika nzira yekutadza yatakaona muzviuru zvesevhisi mishumo, midzi-chikonzero chekuongorora, uye dimensional drift zvidzidzo. Idzi hadzisi mhinduro dzedzidziso. Ivo vakaomeswa nekumanikidza bhasikoro, kupisa kwekuvhunduka kuyedzwa, uye chaiyo-yenyika corrosion kuratidzwa munzvimbo dzakavava gasi.
- Cobalt alloy nozzles - Yakagadzirirwa abrasive slurry jekiseni mune fracturing manifolds. Yakajairwa Stainless shanduro yakanyura 3.2 × nekukurumidza mulab abrasion bvunzo (ASTM G65). Yedu T800 nozzles yakachengeta ± 0.015 mm orifice kushivirira mushure me12,000 kutenderera pa15 m/s kuyerera kwevelocity.
- Cobalt alloy plugs - Inoshandiswa semapofu flange inoisa mune subsea control pods. Yakatsiviwa Inconel 718 apo vatengi vakashuma kutyisa panguva ye-torque-up pa -1 ° C tembiricha yemvura yegungwa. Cobalt yakaderera coefficient yekukwesha yakaderedza kuisa torque ne41% pasina kupa chisimbiso chekuisa chisimbiso.
- AMS 5387 cobalt alloy 6 pombi zvikamu — A system-level solution: cylinder block, valve plate, slipper, swashplate bushing, port plate, uye retainer ring — zvese kubva kune imwe yakasimbiswa kupisa. Inobvisa mutsauko wekupisa kwekuwedzera pakati penzvimbo dzekusangana. Data remumunda rinoratidza 2.8 × kureba kureba nguva pakati pekuwedzeredza maringe neyakasanganiswa-zvinhu magungano.
- Piston pombi humburumbira dzimba - Kwete chete madziro akakora. Izvi zvinosanganisa machani anotonhorera akagadzirwa-muchina uye kusagadzikana-kudzoreredza maflange ekukwira. Tinobata GD&T kushivirira kwakasimba kupfuura ISO 2768-mK pane bore concentricity (≤0.008 mm pamusoro pe 320 mm kureba) nekuti kusarongeka kunofambisa piston shangu kupfeka.
- Mavharuvhu ekumanikidza ane zvigaro zvecobalt zvakabatanidzwa - Kuoma kwechigaro ≥45 HRC, kushata kwepamusoro Ra ≤0.4 µm, uye zero porosity yakasimbiswa kuburikidza ne micro-CT scanning. Inoramba 98.3% yemabhiriji anouya akatadza kuongororwa neultrasonic-hapana mukana wechipiri kana waisa chisimbiso chehydrogen pa700 bar.
- Onboard winch centre shaft rollers — Carburized T800 ine makesi kudzika 1.2–1.5 mm, kusimba kwepakati >85 J pa -40°C. Inopona 15,000+ mitoro inodzoserwa mumunyu-spray yakakurumidza kuyedza uko 42CrMo4 yakundikana pakutenderera 3,200.
Material Consistency Haataurike-Heino Mabatiro Atinozviita
Vamwe vatengesi vanobata cobalt alloy se "imwe simbi isinganzwisisike." Isu tinoibata se metallurgical system. AMS 5387 haina kutsanangurwa nemakemikari chete-inoda kudzora kwakasimba pamusoro pekugovera saizi yezviyo, carbide morphology, uye yakasara yekushushikana mamiriro post-machining. Isu tinobva chete kubva kumagiyo ane yakazara ladle traceability uye tinoda mill test mishumo yezvese zvinotumirwa. Kupisa kwega kwega kunoitwa spectrographic verification, tensile kuyedzwa paASTM E8, uye metallographic ongororo isati yatanga. Kana carbide clustering ichipfuura 5% chidimbu chenharaunda mu as-cast microstructure, isu tinorasa iyo yese yakawanda-kunyangwe kana chemistry ikapfuura. Nekuti mu-sevhisi kupaza kunotanga ipapo, kwete mugungano rekupedzisira.
Machining Haisi Kungocheka-Kudzora Kupisa uye Kudedera
Cobalt alloys anobvisa pa 1/5 chiyero che 316 simbi isina tsvina. Asi dambudziko chairo harisi kukurumidza - kutonga kwekupisa. Pa 300 ° C, simba regoho recobalt rinodonha chete 12%. Izvi zvinoreva kuti maturusi ekucheka anogara akaremerwa, achigadzira kupisa kwakawanda, izvo zvinopfavisa workpiece munharaunda uye inomhanyisa kupfeka kwezvishandiso. Isu tinoshandisa cryogenic nitrogen kutonhora-kwete mhute-pakupedza kutenderedzwa kwezvigaro zvevharuvhu. Upenyu hwekushandisa hunovandudza 3.7 ×. Kutendeseka kwepamusoro kunovandudza: hapana chena-layer kuumbwa, hapana subsurface microcracks yakaonekwa kuburikidza neFIB-SEM. Yese yakakosha nzvimbo inowana CMM kusimbiswa * pamberi * uye * mushure * kupisa kurapwa, nekuti kukanganisa hakugone kufungidzira-kunoyerwa. Uye tinozvinyora.
Yako Inotevera 6 Cobalt Alloy Chikamu Chinotanga Nekudhirowa Wongororo-Kwete Quote
Isu hatiburitse maRFQ ezvikamu zvecobalt. Tinotanga nekududzira kweGD&T. Isu tinocherekedza zvinogona kushungurudza kusimuka mune fillet shanduko. Isu tinokurudzira madiki geometry tweaks-sekuchinja nzvimbo yechamfer ne0.3 mm-inoderedza nguva yekugadzira ne22% pasina kukanganisa basa. Isu tinosimbisa kuyerera kwezvinhu mukudyara kwekudyara tichishandisa yekusimbisa simulation, kwete kufungidzira. Izvi hazvisi pamusoro. Kudzivirira njodzi. Vatengi vanosvetuka nhanho iyi avhareji 3.4 engineering shanduko maodha papurojekiti. Avo vanoita zvekutanga ngarava yekutanga-chinyorwa zvikamu mumazuva gumi nemana, kwete makumi matatu nemasere.
Kana iwe uchitsanangura 6 cobalt alloy chikamu-kana kuongorora imwe-iwe uri kugadzirisa hupenyu hurefu pasi pekunyanyisa. Kwete nyore. Kwete mari chete. Kwete kutora nguva chete. Iwe unoda kutendeka kwedimensional patembiricha, corrosion kuramba muhukasha midhiya, uye kufembera kwechimiro mushure mezviuru zvematenderedzwa. Ndiko uko ruzivo runosangana nekuita. Ndosaka mainjiniya achitsanangura cobalt-uye nei vachivimba nemaitiro ari kumashure kwayo.
