Isihloko: Ukubaluleka Kwamafurnace Okufakwa Kwevacuum Kuma-Smelting Alloys

Lapho ukuncibilikisa ama-alloys, inqubo idinga ukunemba nokulawula ukuqinisekisa ukuthi izakhiwo ezifiselekayo ziyafinyelelwa. Isici esiyinhloko sale nqubo ukusetshenziswa kwesithando somlilo sokungeniswa kwe-vacuum. Lezi ziko zidlala indima ebalulekile ekuncibilikiseni ama-alloys ahlukahlukene, ngalinye linezidingo zalo ezihlukile. Kule bhulogi, sizohlola izinhlobo ezahlukene zama-alloys adinga ukuncibilikiswa ku-ai-vacuum induction isithando somlilokanye nezizathu zesidingo sabo.

Enye yama-alloys avame ukuncibilikiswa kusetshenziswa isithando somlilo sokungeniswa kwe-vacuum insimbi engagqwali. Insimbi engagqwali iyingxubevange enemisebenzi eminingi esetshenziswa ezinhlobonhlobo zezinhlelo zokusebenza, kusukela ezintweni zasekhishini kuya emishinini yezimboni. Inqubo yokuncibilikisa insimbi engagqwali idinga ukulawula okunembile kokwakheka kwengxubevange kanye nokususwa kokungcola okufana nekhabhoni nesibabule. Izithando zokungenisa i-vacuum zinikeza indawo ekahle yokuncibilikisa insimbi engagqwali ngoba zingakwazi ukulawula ngokunembile izinga lokushisa nomkhathi ngesikhathi senqubo yokuncibilikisa.

Enye ingxubevange ebalulekile encibilikisiwe kusetshenziswa isithando sokungenisa ivacuum ingxubevange ye-platinum-rhodium. I-Platinum-rhodium alloy yaziwa ngenani layo eliphezulu lamandla nesisindo kanye nokumelana nokugqwala, okuyenza ibe yinto ebalulekile ezimbonini ezifana ne-aerospace kanye nemishini yezokwelapha. Ukuncibilikisa i-platinum-rhodium alloy kudinga ukuhlanzeka okuphezulu ngoba ngisho nokungcola okuncane kungathinta kakhulu izakhiwo zayo. Izithando zokufakelwa kwe-vacuum ziyakwazi ukudala indawo ehlanzekile edingekayo ukuze kuncibilike ingxubevange ye-platinum-rhodium, okubenza babe bucayi ekukhiqizeni le alloy ebalulekile.

Embonini ye-aerospace, ama-superalloy adingeka kakhulu ukuze akwazi ukumelana namazinga okushisa aphezulu kanye nokucindezeleka kwemishini. Lawa ma-alloys asetshenziswa ekukhiqizeni ama-turbine blades, izingxenye zenjini nezinye izingxenye ezibalulekile zezindiza nemikhumbi-mkhathi. Ukuncibilikisa ama-alloys okushisa aphezulu njenge-Inconel ne-Hastelloy kudinga ukulawula okunembile kwezinqubo zokuncibilika nokuqiniswa kanye nokususwa kokungcola. Izithando zokungenisa i-vacuum zinikeza izimo ezidingekayo zokuncibilikisa ama-alloys asezingeni eliphezulu ukuze kukhiqizwe izinto ezisezingeni eliphezulu, ezisebenza kahle kakhulu zokusetshenziswa kwe-aerospace.

Embonini yezimoto, ama-alloys e-aluminium asetshenziswa kakhulu ngenxa yezakhiwo zawo ezingasindi futhi ezimelana nokugqwala. Ukuncibilikisa ama-alloys e-aluminium kudinga ukulawula ngokucophelela izinqubo zokuncibilika nokukhipha ukuze kuqinisekiswe ukuthi izakhiwo zemishini ezifunwayo ziyafinyelelwa. Izithando zokungenisa ivacuum zihlinzeka ngokulawula okunembayo kwezinga lokushisa kanye nomoya odingekayo ukuze kuncibilike ama-alloys e-aluminium, okubalulekile ekukhiqizeni izinto zezimoto zekhwalithi ephezulu.

Embonini yezokwelapha, ama-alloys e-biocompatible afana ne-titanium alloys nama-cobalt-chromium alloys asetshenziswa ekukhiqizeni izimila kanye namadivayisi wezokwelapha. Ukuncibilikisa lezi zingxubevange kudinga izinga eliphezulu lokuhlanzeka kanye nokulawulwa kokubunjwa ukuze kuqinisekiswe ukuthi zihlangabezana nezidingo eziqinile zokuhambisana kwezinto eziphilayo kanye nezakhiwo zokukhanda. Izithando zokufakelwa kwe-vacuum zinikeza izimo ezidingekayo zokuncibilikisa ama-alloys ahambisanayo, okuwenza abaluleke kakhulu ekukhiqizeni izinto zokwelapha.

Embonini ye-electronics, ama-alloys ethusi asetshenziselwa ukuqhutshwa kwawo kagesi kanye nezakhiwo ezishisayo. Ukuncibilikisa ama-alloys ethusi kudinga ukulawula okunembile kokubunjwa nokususwa kokungcola ukuze kuqinisekiswe ukuthi izinto ezifiselekayo zikagesi nemishini ziyafinyelelwa. Izithando zokufakelwa kwe-vacuum zinikeza indawo ekahle yokuncibilikisa ama-alloys ethusi ukuze kukhiqizwe izinto ezisezingeni eliphezulu zokusetshenziswa kwe-elekthronikhi.

Kafushane, izithando zokufakelwa kwe-vacuum zidlala indima ebalulekile ekuncibilikeni kwama-alloys ahlukahlukene, ngalinye linezidingo zalo ezihlukile. Kusukela ensimbi engagqwali kuya ku-titanium, kusukela kuma-alloys aphezulu okushisa kuya kuma-alloys e-aluminium, kusukela kuma-alloys e-biocompatible kuya kuma-alloys ethusi, lezi ziko zihlinzeka ngezimo ezidingekayo zokukhiqiza izinto ezisezingeni eliphezulu zezimboni ezihlukahlukene. Ukulawulwa okunembile kwezinga lokushisa, umkhathi nobumsulwa okufinyelelwa ngokuncibilika kwe-vacuum induction kubalulekile ukuze kuhlangatshezwane nezidingo eziqinile zamaalloyi esimanje. Njengoba ubuchwepheshe buqhubeka nokuthuthuka, indima yeziko lokungeniswa kwevacuum ekuncibilikiseni ingxubevange izoba bucayi kakhulu ekuhlangabezaneni nezidingo zezimboni ezahlukahlukene.
