Ukuphathwa Kwesayensi Yemijikelezo Yokulungisa Ingxubevange ye-Titanium

Ama-alloy e-Titanium asetshenziswa kakhulu ku-aerospace, kumadivayisi ezokwelapha, kanye-nasemikhiqizweni yabathengi ephezulu ngenxa yokumelana nokugqwala okuhle kakhulu, amandla aphezulu, nezici ezingasindi. Kodwa-ke, naphezu kokuqina kwazo okukhethekile, ukuphathwa komjikelezo wokulungiswa kwesayensi kuhlala kubalulekile ukuze kuqinisekiswe ukusebenza kwazo{2}}zesikhathi eside.

Umjikelezo wokunakekela we-titanium alloys uncike ngokuyinhloko endaweni yokusebenza kanye nemidiya abachayeka kuyo. Ezimweni ezivamile zomkhathi, ifilimu ye-oxide ezinzile yakha phezu kwama-alloys e-titanium, ehlinzeka ngokuvikeleka okuhle kakhulu kokugqwala. Ngakho-ke, ukuhlanza okujwayelekile njalo ezinyangeni eziyisi-6 kuya kweziyi-12 kwanele. Kodwa-ke, ezimeni zokuchayeka isikhathi eside-ezindaweni zasolwandle noma-ezindaweni ezinosawoti ophakeme, ama-chloride angase alimaze ifilimu ye-oxide, ngakho ukuhlola kunconywa ukuthi kufinyezwe ezinyangeni ezi-3 kuya kwezingu-6, ngokusebenzisa okokuhlanza okungathathi hlangothi ukuze kususwe ngokushesha insalela kasawoti.

Ezingxenyeni ezigcizelelwe kakhulu ze-titanium alloy ezisetshenziswa ezimbonini noma kwezokwelapha, njengama-blade enjini yendiza noma izinto ezifakelwayo, izikhawu zokulungisa ziqine kakhulu. Izidingo zokuguga kwemishini noma ze-biocompatibility zingasho ukuhlolwa okukhethekile njalo ngekota noma izinyanga eziyisithupha, okuhlanganisa ukuhlolwa kobuqotho kanye nokuhlola{1}}okungonakalisi ukuvimbela ukusakazeka kwe-microcrack. Ngaphezu kwalokho, okokusebenza kwe-titanium alloy kuvezwe emithonjeni yamakhemikhali (njengama-acids nama-alkali) kudinga uhlelo lokulungisa oluklanyelwe izimo ezithile zokusebenza. Ngokuvamile kuyanconywa ukuthi ugeze kahle okokusebenza ngemva kokusetshenziswa ngakunye, futhi uhlele ukunakekelwa okuphelele ngemva kwesikhathi esithile sokusebenza (isb, amahora angu-500-1000).

Ukunakekelwa kwansuku zonke kufanele kubeke phambili ukuhlanza okuthambile ukuze kugwenywe ukuklwebheka ezintweni eziqinile noma ukugqwala okuvela kuma-asidi aqinile nama-alkali. Isitoreji kufanele sibe kude nemithombo yokugqwala kwe-electrochemical futhi sigcinwe somile futhi{1}}singenawo umoya. Izinto zokubopha namajoyinti kufanele zihlolwe njalo ukuze kuvinjwe umonakalo wokukhathala obangelwa ukugxila ekucindezelekeni.

Ishejuli-echazwe kahle yokulungisa ayigcini nje ngokunweba impilo yesevisi ye-titanium alloys kodwa futhi igcina izinzuzo zayo zokusebenza. Abasebenzisi kufanele bakhe uhlelo lokunakekela lomuntu siqu olusekelwe ezimeni zabo zohlelo lokusebenza kanye nezincomo zomkhiqizi ukuze baqinisekise ukuthi okokusebenza kuhlala kusesimweni esifanele.
