Uruhare rwo Kwinjiza Vacuum Gushonga (VIM) mugutunganya imiyoboro

Mu gutunganya imiyoboro, vacuum induction gushonga (VIM) ni ihurizo ryingenzi mugutegura ibikoresho fatizo kumiyoboro ya - iherezo nka nikel - ishingiye ku mavuta hamwe na titanium. Muguhuza ubushyuhe - gushonga hamwe nibidukikije bya vacuum, birashobora kugera ku ntego nyinshi: icya mbere, birashobora kugenzura neza ibivanze. Irashonga ibyuma bibisi mubishyushya hamwe na electromagnetic yumurima, ikongeramo neza ibintu bivangavanze, igenzura byimazeyo igipimo cyibigize (hamwe nikosa rya munsi cyangwa iringana na 0,05%), irinda umwanda nka S na P (hamwe nibirimo munsi ya 0.001%), kandi ikemeza uburinganire bwibintu byongeweho; icya kabiri, irashobora gukuraho imyuka n'umwanda uhindagurika. Mugihe cyimyuka ya munsi ya 10⁻³ Pa cyangwa ihwanye na 10⁻³ Pa, ikuraho neza imyuka nka H₂, N₂, na O₂ (hamwe na H₂ Ntoya cyangwa ihwanye na 1ppm na O Nto cyangwa ihwanye na 50ppm) kimwe no - gushonga - ingingo zanduye, bikarinda gushiraho imyenge nibice mugihe cyo gutunganya amavuta ashyushye; icya gatatu, irashobora kugabanya umwanda wa kabiri. Ibidukikije byafunzwe bitandukanya ingaruka ziterwa nu mwuka n’itanura, birinda ko habaho nitride na okiside; kane, ishyiraho urufatiro rwo gutunganya nyuma. Ikoresha induction ikangura kugirango hamenyekane uburinganire bwubushyuhe nubushyuhe bwashonga, bigabanye gutandukanya ibice, binonosora ibinyampeke (kuva kurwego rwa mm kugeza kurwego rwa μm) mugucunga igipimo cyo gukonja, kandi bitezimbere plastike ikora.
