Izinyathelo Zokusebenzisa I-Titanium Alloys

Ingxubevange ye-Titanium, -amandla aphezulu,{1}}ukuminyana okuphansi, kanye nokugqwala{2}}izinto zensimbi ezingazweli, isetshenziswa kakhulu ku-aerospace, izinto zezokwelapha, okokusebenza kwamakhemikhali, nezinye izinkambu. Kodwa-ke, ngenxa yezakhiwo zayo ezihlukile zomzimba namakhemikhali, kufanele kuthathwe izinyathelo zokuphepha ezilandelayo ngesikhathi sokucubungula, ukusetshenziswa, nokugcinwa.

1. Ukucubungula Izinyathelo Zokuqapha

Ama-alloys e-Titanium ane-thermal conductivity engalungile, engakwazi ukukhiqiza kalula amazinga okushisa asendaweni ngesikhathi sokucubungula, okuholela ekwenyukeni kokugqoka kwamathuluzi. Ngakho-ke, amathuluzi okusika ama-carbide noma e-ceramic kufanele asetshenziswe, futhi isivinini esifanelekile sokusika kanye nokupholisa kufanele kusetshenziswe. Ngaphezu kwalokho, ama-alloys e-titanium asabela kalula ngezakhi ezifana ne-oxygen ne-nitrogen emazingeni okushisa aphezulu, enze ama-brittle compounds. Ukushisa ngokweqile kufanele kugwenywe ngesikhathi sokucubungula. Ukwelashwa kokushisa ngaphansi kwegesi ye-inert noma i-vacuum kuyanconywa.

2. Isitoreji Nezokuthutha

Ama-alloys e-Titanium azwela izinto ezibolayo njengama-ion e-chloride namanzi olwandle endaweni ezungezile futhi kufanele agcinwe kude nezinto ezinjalo. Kunconywa ukuthi zigcinwe endaweni eyomile,{1}}enomoya omuhle futhi ehlukaniswe nezinsimbi ezisebenzayo (njenge-aluminium ne-magnesium) ukuze kuvinjelwe ukubola kwe-electrochemical. Sebenzisa{3}}ukupakishwa okungathinteki ngesikhathi sokuthutha ukuze ugweme ukuklwebheka, njengoba umonakalo ongaphezulu kuma-alloys e-titanium ungasheshisa ukugqwala kwendawo.

3. Ukusetshenziswa Nokugcinwa

Uma isetshenziswa-ezindaweni zokushisa eziphezulu noma ezidle kakhulu, kubalulekile ukukhetha ibanga elifanele le-titanium alloy (elifana ne-Ti-6Al-4V noma i-Ti-3Al-2.5V). Hlola njalo isimo esingaphezulu sezingxenye ze-titanium alloy. Uma kutholwa ukugqwala noma imifantu, yilungise noma uyishintshe ngokushesha. Emkhakheni wezokwelapha, izimila ze-titanium alloy kufanele zihambisane ngokuqinile namasu e-aseptic futhi zigweme ukuthintana nama-acids aqinile nezisekelo ukuvimbela ukuwohloka kwezinto ezibonakalayo.

4. Ukushisela nokuhlanganisa

I-Titanium alloy welding kufanele yenziwe ngaphansi kwesihlangu segesi esingasebenzi (njenge-argon) ukuvimbela i-oxidation kanye ne-nitriding. Indawo yokushisela kufanele ihlanzwe kahle ukuze kugwenywe ukungcola okunjengamafutha nokungcola okungase kuthinte izinga lokushisela. Ngaphezu kwalokho, lapho uhlanganisa ama-alloys e-titanium kwezinye izinsimbi, ama-bolts noma i-adhesive bonding kunconywa ukugwema ukwakheka kwezigaba eziphukayo ezibangelwa ukushisela okuqondile kwe-fusion.

Kafushane, kuyilapho ama-titanium alloys enikeza ukusebenza okuhle kakhulu, izimiso eziqinile zohlelo lokusebenza kufanele zilandelwe ukuze kuqinisekiswe ukuthi{0}}zinzile futhi zithembekile.
