Hobaneng ha Cobalt Alloy 6 e Batla ho Feta Mabenkele a Tloaelehileng a CNC
Cobalt Alloy 6 (AMS 5387) ha se "superalloy e 'ngoe feela." Motheo oa eona oa 60% oa cobalt, 30% ea chromium, le tungsten/nickel matrix e fana ka khanyetso e ikhethang ea ho tsofala, mokhathala o futhumatsang le ho bola ha metsi - empa ka litšenyehelo tse phahameng tsa ho sebetsa. Mehala e tloaelehileng ea qoqa. Libaka tse nang le carbide tse ngata li khelosa lisebelisoa tsa ho itšeha. Libaka tse anngoeng ke mocheso lia phatloha nakong ea ho imolla khatello ea maikutlo ka mor'a mochini. Re lekanyelitse litekanyetso tsa ho roala lisebelisoa 4.2× holimo ho Co-6 khahlano le Inconel 718 tlas'a liphepelo le lebelo le tšoanang. Katleho e ipapisitse le lintho tse tharo tseo e seng tsa lipuisano: taolo ea microstructure e entsoeng esale pele, maano a ho feto-fetoha a li-multi-axis toolpath, le tlhahlobo ea nako ea sebele ea mocheso nakong ea ho qetela.
Ke ka lebaka leo kopanyo ea ho qetela e bohlokoa ho feta bokhoni ba CNC bo ikemetseng. Feme ea likarolo tse 6 ea cobalt e tlameha ho laola ketane e felletseng - ho tloha ho ts'etello ea matsete a matsete le ho laola ho pholile ho tiisa ho imolla khatello ea maikutlo pele e otloloha, ebe likheo tse tataisoang ke CMM tse kentsoeng ka daemane. Ntlo ea pompo ea moreki ea AMS 5387 ea moreki e ile ea hloleha ho etsa liteko habeli. Sesosa sa ho qala? Mofani oa lisebelisoa o ne a sebelisa moea o pholileng ho e-na le sebopi se laoloang ke sebōpi. Li-microcracks tse entsoeng meeling ea lijo-thollo-tse sa bonahaleng ka tlhahlobo ea pono, tse bolaeang tlas'a cyclic loading. Lokisa? Ts'oarelo e felletseng ho tloha ho billet e tala ho ea ho tlaleho ea ho qetela ea kalafo ea mocheso, e netefalitsoeng ho latela ASTM E112 le AMS 2750E.

- Mehala e tiisitsoeng ka lintho tse bonahalang: Eseng feela "re amohela likoloto tsa hau tsa Co-6." Bokhoni ba 'nete bo bolela ts'ebetso ea matsete a ka tlung e nang le vacuum-pour, netefatso ea sebopeho sa khetla ea ceramic, le tlhahlobo e hlakileng ea sehlopha se seng le se seng sa ho qhibiliha.
- Boima ba tsamaiso ea Hybrid: Metheo ea Sand-cast Co-6 e hloka boitokiso bo fapaneng ba holim'a metsi ho feta li-nozzles tsa matsete. Feme ea likarolo tsa cobalt 6 e tlameha ho laola ka bobeli - le ho tseba nako ea ho chencha lipakeng tsa tsona ho ipapisitsoe le botenya ba lebota, boima ba likarolo le litlhoko tsa boima ba mocheso.
- Meaho ea motheo ea tlhahlobo ea GD&T: Ho lekanya mamello ea boemo ba 0.005 mm plug ea Co-6 ea bophara ba 120 mm e hloka ho feta CMM. E hloka lilaboratori tsa metrology tse tiisitsoeng, li-gage blocks tse netefalitsoeng tse ka latelloang ho NIST, le basebetsi ba koetlisitsoeng ka ASME Y14.5–2018 profil tolencing—eseng feela linear litements.
- Netefatso e sebetsang ho feta geometry: Na plug eo ea cobalt alloy e tiisa ho 450 ° C le 180 bar? Na nozzle e boloka angle ea ho fafatsa ka mor'a linako tse 10,000 tsa mocheso? Lifeme tsa 'nete tsa cobalt tse 6 li etsa liteko tse potlakileng tsa bophelo - eseng feela licheke tsa maemo.
