Kwiga titanium aluminide turbocharger casting

Nukoresha cyane amavuta ya titanium mumasoko yinganda zikora inganda kubera igipimo cyihariye cyimbaraga-uburemere, kurwanya kuvunika, hamwe no kurwanya ruswa. Umubare munini wibigo uhitamo gukoresha Titanium alloy TC11 aho gukoresha TC4 mugukora imashini zitera ibyuma, bitewe numutungo mwiza wo kurwanya umuriro hamwe nubushobozi bwo gukora mubushyuhe bwinshi mugihe kirekire. Amavuta ya Titanium ni ibikoresho bya kera bigoye kumashini kubububasha bwabyo bwihariye bugumana ubushyuhe bwo hejuru hamwe nubushyuhe buke bwumuriro biganisha ku bushyuhe bukabije. Kubintu bimwe na bimwe bya aero-moteri, nkibimoteri, byahinduye isura, biragoye guhaza ubuziranenge bwo hejuru kandi buhanitse busabwa hakoreshejwe gusa urusyo.

Muri moteri yimbere yimodoka, rotor ya turbocharger yagize uruhare mukwongera ingufu zingufu ndetse no kugabanya lisansi, kubera ko gaze ya gaze iteza imbere gufata neza nta yandi mavuta yakoreshejwe. Nyamara, rotor ya turbocharger ifite inenge yica yitwa '' turbo-lag '' idindiza imikorere ya leta ihoraho ya turbocharger munsi ya 2000 rpm. Titanium aluminide irashobora kugabanya ibiro kugeza kimwe cya kabiri cya turbocharger isanzwe. Byongeye kandi, TiAl alloys ifite ihuriro ryubucucike buke, imbaraga zidasanzwe, imiterere yubukanishi, hamwe nubushyuhe. Kubwibyo, TiAl alloys irashobora gukuraho ikibazo cya turbo-lag. Kugeza ubu, mu gukora turbocharger, ifu ya metallurgie hamwe na casting byakozwe. Nubwo bimeze bityo ariko, biragoye gukoresha ifu ya metallurgie yifu mubikorwa bya turbocharger, kubera kutumva neza no gusudira.

Urebye uburyo buhendutse, gushora imari bishobora gufatwa nkikoranabuhanga rishingiye ku bukungu kuri TiAl alloys. Nyamara, turbocharger ifite ibice byombi bigoramye kandi byoroheje, kandi nta makuru akwiye nko guterwa no gutembera hamwe nubushyuhe bwubushyuhe, ubushyuhe bwashushe nimbaraga za centrifugal. Icyitegererezo cyo gukina gitanga uburyo bukomeye kandi buhendutse bwo kwiga imikorere yibipimo bitandukanye.
