umkhiqizo

Ukwenza inaliti engcono, bese kuba nakho okungcono ngenkathi odokotela abahlinzayo befaka ama-sutures ekuhlinzeni. Onjiniyela basembonini yemishini yezokwelapha bazame ukwenza inaliti ibe bukhali, iqine futhi iphephe emashumini eminyaka adlule. Umgomo uwukuthuthukisa izinaliti ze-sutures ngokusebenza okuqine kakhulu, okubukhali kungakhathaliseki ukuthi mangaki ukungena okufanele kwenziwe, okuphephile kakhulu okungakaze kuphule ithiphu kanye nomzimba ngesikhathi sokudlula izicubu. Cishe zonke izigaba ezinkulu ze-alloy zahlolwa ukusetshenziswa kwezinaliti zokuthunga ukuze zenziwe ngenhla. Olunye uhlobo lwamazwe ngamazwe lusebenzisa yonke ingxubevange yezinga elikhethekile iqukethe izingxenye zensimbi eziyigugu ezingandile ukuze kugcinwe lo mgomo.

Ezomnotho futhi ezithengekayo njalo ukukhetha emakethe. Ingxubevange yezithombe ze-sutures akulula ukuyicubungula kanye nokukhiqiza okuletha izindleko eziphezulu. Ngakolunye uhlangothi, akuzona zonke izinhlinzeko ezinesicelo kulokhu kusebenza kwenaliti engenhla. Ngisho nabanye odokotela abahlinzayo bathanda inaliti ukuthi ithambe kancane. Ukuchaza ubukhali benaliti nge-Penetration Force Test, ukuchaza amandla enaliti ngokuhlolwa kwe-Bending Moment, ukuchaza ukuphepha ngokuhlolwa kwe-Ductility. Ukuze kuthuthukiswe ukusebenza kwe-Penetration Force, ukunemba kanye nobuchwepheshe bokugaya okuncane kwethulwa embonini egcine lo mgomo. Inselele ibhalansi ye-make balance phakathi kwe-Gonding Moment kanye ne-Ductility, njengoba ingxubevange iba ntekenteke kuyilapho ikwenza kube nzima ukuqina, futhi lokhu kunquma ukukhetha kwengxubevange.

Izinaliti eziningi ze-sutures zenziwe yi-ANSI 302/304 ingxubevange manje, ngaphambi kwe-ANSI 302/304, i-alloy yochungechunge engu-400 yayisetshenziswa kabanzi ngezinaliti ze-Sutures emashumini eminyaka, kufaka phakathi i-420J2, 455F ne-470.

I-420J2 iyingxubevange yezomnotho kakhulu yezinaliti ze-sutures. Insimbi engu-420J2 iyinsimbi engagqwali ye-martensitic, esetshenziswa ngemuva kokucisha nokushisa. Ukusebenza okubandayo nokusebenza kwe-welding akukuhle, ngemuva kokushisela kufanele kube ukwelashwa kokushisa ngokushesha, ukuvimbela ukuqhekeka. Inokusebenza okuhle ngaphansi kwesimo sokuthungatha.

I-alloy 455 iyinsimbi engagqwali eqinile ye-martensitic eqinile, enesimo esithambile, esine-annealing singakhiwa, kuphela ukwelashwa okulula kokushisa, ungathola amandla ayingqayizivele aqinile, ukuqina okuhle nokuqina. I-Custom 455 ingacutshungulwa esimweni esishubile futhi ingashiselwa njengemvula eqinile insimbi engagqwali. Njengoba izinga lokuqiniswa komsebenzi lincane, kungaba yizinhlobonhlobo zokwakheka okubandayo. I-alloy 470 nayo iyinsimbi engagqwali ye-martensitic ephathwayo ekhethekile, ehlinzeka ngenaliti eqinile.

Ukuhlinzwa kwenhliziyo nemithambo yegazi kudinga ukusebenza okungcono njengoba ngenhla kanye nokuhlinza kwamehlo, okwenziwa nge-302/304 alloy. Ukuhlinzwa okuningi emnyangweni wezimo eziphuthumayo akudingi isicelo esinjalo esivame ukwenziwa nge-420J2 ne-455 inaliti, amakhodi ambalwa kuphela enziwe nge-alloy engu-470.
