Ki kalite metal se tantal? Ki pri li ye?

1) plastik fòme pwosesis ‌hot pwosesis ‌‌forging ak èkstruzyon ‌: tantal yo tantal te bezwen milti-direksyon fòje oswa sòti nan 1100-1250 degre elimine domaj yo nan estrikti a jete ak ogmante dansite a plis pase 98%; Pwosesis la nan alyaj tantal mande pou pwoteksyon gaz inaktif yo anpeche oksidasyon pénétration ak fant 28. Pwosesis ‌pure tantal ka dirèkteman fòje oswa lonje nan tanperati chanm, ki se apwopriye pou pwosesis la nan pati presizyon tankou fil ak plak mens, men mak sifas bezwen yo dwe kontwole 8.

2) .powder preparasyon metaliji ‌process koule ‌Mixed Tantalum poud ak poud alyaj → frèt isostatik peze → segondè tanperati sinterizasyon (1300-2050 degre \/segondè vakyòm) → rkwir → machining; the porosity can reach 14.89%, which is used for medical porous implants 6. ‌Performance characteristics‌Compared with vacuum electron beam melting, powder metallurgy tantalum alloy has higher strength (such as Ta-20Zr alloy), but its plastic deformation ability is slightly poor, and the brittle inclusion content needs to be reduced through oxygen control process6.

3) Precision Machine Teknoloji ‌ Fòmasyon Pwosesis ‌Wire Cutting\/lazè Cutting‌: Processing konplèks pati ki gen fòm espesyal (tankou tantal bag, tantal tantal), presizyon kwen nan ± 0 02mm28; ‌Cnc Milling‌: sifas brutality ra<0.4μm, flatness error ≤0.02mm/100mm8. ‌Surface treatment‌Divided and step-by-step polishing technology: Real-time adjustment of polishing parameters through film thickness fitting model to achieve uniform film thickness of lithium tantalate bonding sheet (secondary polishing after error compensation)1.

4) Smelting ak rediksyon teknoloji ‌ore dekonpozisyon ‌use idrofluoric asid dekonpozisyon metòd oswa sodyòm idwoksid metòd k ap fonn, konbine avèk ekstraksyon sòlvan (tankou methyl isobutyl kwiv) separe tantal ak niobium35. ‌ Metal rediksyon ‌‌ Sosyal rediksyon tèmik Metòd ‌: potasyòm fluorotantalate (K₂taf₇) redwi pou pwodwi tantal poud ak gwo zòn sifas espesifik, ki apwopriye pou CAPACITOR FACTURACTURAT5; ‌ Metòd rediksyon tèmik: pentoksid tantal la redwi a tantal tantal, ki gen pri ki ba men yon ti kras pi ba pite (ki vin apre raffinage obligatwa) 35.

5) Pwosesis espesyal (Sib fabrikasyon materyèl)‌Obligatwa Teknoloji‌tantalum sib (Φ 200-450 mm × 6-12 mm) se estokaj nan plak la tounen kwiv pa soude difizyon, ak koòdone rezistans a tèmik se<1×10⁻⁶ m²·K/W7. ‌Micro-control‌EBM smelting refines the grains to 20-50μm, and vacuum annealing (1200℃×2h) eliminates stress to form a uniform β phase structure67.
