Xa abantu abaninzi besiva 'izahlulo ze-nickel alloy casting', bacinga ngoko nangoko malunga nokumelana nobushushu obuphezulu okanye iitshati zokubola. Leyo yintetho yencwadana. Ibali lokwenyani liqala xa uzama ukugalela loo nto ityhidiweyo, i-viscous alloy ibe ngundo kwaye ulindele ukuba iziphathe. Umsantsa phakathi kweepropathi zezinto zethiyori kwiphepha ledatha kunye nenyani yesandi, ukuphosa okunomatshini apho lonke eli shishini lihlala okanye lifa. Ayikokukhetha nje i-Inconel 718 ngaphezulu kwe625; imalunga nokuqonda ukuba ulwakhiwo lweenkozo luyakwenza njani umbindi, okanye kutheni ipateni yewax ebonakala igqibelele ikhokelela kwindawo ekhutshiweyo emva konyango lobushushu. Ndibone uyilo oluninzi kakhulu olucacisa i-nickel alloy ngezizathu ezingalunganga, ezikhokelela ekugqithiseni kweendleko kunye nokusilela obekunokuthi kuphetshwe ngentwana yolwazi olusebenzayo.
I-alloy ayisiyonto nje ingxubevange
Makhe sicacise. Ufuna i-impeller yepompo yendawo yenkonzo emuncu, ngoko uhlala kwi-Monel. Isiqalo esihle. Kodwa yeyiphi indlela yokufumana? Ngokuphosa utyalo-mali, ufumana ijometri entsonkothileyo, kodwa ukulawula i-aluminium kunye nomxholo we-titanium ngexesha lokunyibilika ukuthintela ukukrazula okushushu kumacandelo amancinci kuba yidabi lasebusuku le-metallurgist. Ndikhumbula iprojekthi kunye Qingdao Qiangsenyuan Technology Co., Ltd.(QSY) apho sasityhala imida kwindawo encinci yeHastelloy C-276. Inkcazo yayiqinile. Indlela yabo yayingeyonto nje yokubetha imichiza; yayimalunga nobushushu bangaphambili beqokobhe leceramic. Iphantsi kakhulu, kwaye intsimbi yayiza kubanda ngokukhawuleza, idala uxinzelelo; phezulu kakhulu, kwaye usengozini yokusabela kwe-metal-shell. Ngala ma-nuances amashumi amathathu eminyaka kuwo iqokobhe ngundo ukuphosa kwaye utyalo mali yizisa etafileni-iinkcukacha ongazi kuzifumana kwincwadi yesandla.
Ke kukho icala lomatshini, elihlala lingahoywa kwinqanaba loyilo. Ukuphosa indawo ekufutshane ne-net-shape kwi-Inconel 738LC yinto enye, kodwa ke kufuneka ugrumbe imingxuma yokupholisa kuyo.
