Ekuthuthukisweni okuphawulekayo embonini ye-metallurgical, ukufakwa kwe-titanium ngeI-ASTM/ASMEIzinga lenze uphawu, lihlinzeka ngezixazululo eziguquguqukayo emikhakheni ehlukahlukene. Ukwethulwa kwalokhu kufakwa kuletha izinga elisha lokuqina, amandla, nokumelana nokugqwala, okunikeza izinzuzo ezinkulu ezimbonini ezifana ne-aerospace, ukucubungula amakhemikhali, uwoyela negesi, nokunye. I-Titanium, eyaziwa ngesilinganiso sayo esingenakuqhathaniswa samandla nesisindo, sekuyisikhathi eside iyinto efunwa kakhulu ezimbonini ezidinga ukusebenza okuphezulu ngaphansi kwezimo eziyinselele. Ngokungezwa kokufakwa okujwayelekile kwe-ASTM/ASME, amandla e-titanium afinyelele ukuphakama okusha.
Lokhu kufakwa kuthobela ikhwalithi eqinile kanye nemibandela yokusebenza esungulwe yi-American Society for Testing and Materials (ASTM) kanyei-American Society of Mechanical Engineers (ASME), ukuqinisekisa ukwethembeka nokuhambisana okukhethekile. Enye yezinzuzo ezinkulu zokufakwa kwe-titanium ngezinga le-ASTM/ASME ilele ekhonweni lazo lokumelana nezinga lokushisa elidlulele nezingcindezi. Lokhu kuzenza zilungele ukusetshenziswa embonini kawoyela negesi, lapho zingachayeka khona ezindaweni ezinokhahlo, umfutho ophakeme, noketshezi olubolayo. Ukuqaliswa kwalokhu kufakwa kunciphisa kakhulu izindleko zokulungisa futhi kuthuthukisa ukuphepha kukonke kokusebenza.
Ngaphezu kwalokho, imboni ye-aerospace nayo yamukelekileukufakwa kwe-titaniumnjengomshintshi womdlalo. Ngezakhiwo zayo ezingasindi namandla aphezulu, i-titanium ilingana kahle nezakhiwo zezindiza. Ngokusebenzisa ukufakwa okujwayelekile kwe-ASTM/ASME, imboni manje ingafinyelela ikhwalithi ephezulu, ukunemba, nokusebenza ezingxenyeni zendiza, iqinisekisa izindiza eziphephile nezisebenza kahle kakhudlwana. Imboni yokucubungula amakhemikhali, esebenzelana noketshezi olubola kakhulu, izuza kakhulu ekumelaneni nokugqwala kokufakwa kwe-titanium. Izinto zendabuko zivame ukunqotshwa ukuhlaselwa kwamakhemikhali, okuholela ekushintshweni njalo kanye nesikhathi sokuphumula. Kodwa-ke, ukufakwa kokufakwa kwe-ASTM/ASME kwe-titanium okujwayelekile kunikeza isisombululo esiqinile, kuncishiswe imizamo yokulungisa kanye nokwandisa umkhiqizo.
Esinye isicelo esiphawulekayo sokufakwa kwe-titanium sisendaweni yezokwelapha. Imvelo ye-Titanium engenabo ubuthi kanye nokuvumelana kwe-biocompatibility kuyenza ibe inketho ekahle yokufakelwa kwezokwelapha, okufana namalunga okwenziwa, izifakelo zamazinyo, namadivayisi enhliziyo. Ngesiqinisekiso esingeziwe samazinga we-ASTM/ASME, umphakathi wezokwelapha ungathembela ekuthembekeni nasekuphepheni kokufakwa kwe-titanium, okuthuthukisa kakhulu imiphumela yesiguli. Ngaphezu kwalokho, ukwethulwa kokufakwa kwe-titanium ngezinga le-ASTM/ASME kuvula amathuba amasha amaphrojekthi ahlukahlukene wokwakha. Kusukela kumabhuloho nezinkundla kuya kwezimangaliso zezakhiwo, ukufakwa kwe-titanium kunikeza ukuguquguquka okukhulu kwedizayini nokuhlala isikhathi eside uma kuqhathaniswa nezinto ezijwayelekile. Ukumelana kwazo nokugqwala, isimo sezulu, nokuguga kuqinisekisa ukuthi izakhiwo zihlala ziqinile futhi zijabulisa ngobuhle iminyaka ezayo.
Kodwa-ke, kubalulekile ukuqaphela ukuthi ngaphandle kwezinzuzo ezimangalisayo zokufakwa kwe-titanium ngezinga le-ASTM/ASME, izindleko zakhona zihlala ziphakeme uma kuqhathaniswa nokufakwa kwendabuko. Izinqubo eziyisipesheli zokukhiqiza kanye nezinyathelo eziqinile zokulawula ikhwalithi zinomthelela ekwenyukeni kwezindleko. Noma kunjalo, izinzuzo zesikhathi eside nokuqina okulethwa ukufakwa kwe-titanium ezimbonini kuyadlula ukutshalwa kwezimali kokuqala.
Sengiphetha, ukufika kokufakwa kwe-titanium ngezinga le-ASTM/ASME kuphawula ingqopha-mlando embonini yensimbi. Lokhu kufakwa kunikeza amandla akhethekile, ukumelana nokugqwala, nokuqina, okuwenza abe wusizo emikhakheni ehlukahlukene. Ukusuka emkhathini kuya kwezokwelapha, uwoyela negesi kuya ekwakhiweni, ukusetshenziswa okubanzi nezinzuzo zokufakwa kwe-titanium kuqinisekisa ikusasa eliqhakazile nelithuthuke kakhulu lezimboni emhlabeni wonke.
