Izitulo ezinamavili zombane, njengesixhobo esitsha sokuhamba kancinci, siye saqatshelwa kancinci kancinci ngabantu abadala nabakhubazekileyo abaninzi. Singayithenga njani i-isitulo esinamavili sombane esingabizi kakhulu?

Njengomntu osebenza ngaphakathi kushishino kangangeminyaka engaphezu kweshumi, ndingathanda ukukunceda ngokufutshane ukusombulula le ngxaki kwiinkalo ezahlukeneyo. Into yokuqala ekufuneka siyazi kukuba imeko yeqela ngalinye kunye nomsebenzisi kunye nendawo yokusetyenziswa kwayo yahlukile, nto leyo ekhokelela ekwahlukeni kweemveliso ezithengiweyo.

Izinto eziqhelekileyo zahlulwe ngokubanzi zibe yi-carbon steel, i-aluminium alloy, i-aerospace titanium aluminium alloy kunye ne-magnesium alloy, i-carbon fiber.

1. Izinto zentsimbi yekhabhoni.

Isakhelo sentsimbi yekhabhoni sisetyenziswa kakhulu kwizitulo ezinamavili ezinzima kwaye ezinye iimpawu eziveliswa ziifektri ezincinci, izitulo ezinamavili ezinzima zisebenzisa isakhelo sentsimbi ukuze zonyuse ubulukhuni bomzimba kunye nokuzinza kokuqhuba, umzekelo, iilori ezininzi ezinkulu zinezakhelo zentsimbi kwaye iimoto ezincinci zingasebenzisa i-aluminium yisizathu esifanayo, iifektri ezincinci zivelisa izitulo ezinamavili zisebenzisa izakhelo zentsimbi kuba olu hlobo lweenkqubo zokucubungula kunye nokuwelda ziphantsi kakhulu, iindleko nazo ziphantsi kakhulu. Isizathu sokuba iifektri ezincinci zisebenzise izakhelo zentsimbi kukuba azidingi msebenzi mkhulu kunye nokuwelda kwaye zixabiso liphantsi.

2. I-aluminium kunye ne-titanium-aluminium alloy

I-aluminium alloy kunye ne-titanium alloy, ezi zinto zimbini zithatha indawo enkulu kwimarike yezitulo ezinamavili zombane, ziyi-7001 kunye ne-7003 iintlobo ezimbini ezahlukeneyo ze-aluminium, oko kukuthi, i-aluminium enezinye izinto ezahlukeneyo ezixutyiweyo kuyo, iimpawu zazo eziqhelekileyo ziphantsi koxinano kunye namandla aphezulu, ukumelana okuhle kweplastiki kunye nokumelana nokugqwala, ukuyibeka ngendlela ecacileyo ilula kwaye yomelele kwaye icwangciswa kakuhle, ngelixa i-titanium aluminium alloy ikwaziwa njenge-titanium-aluminium alloy ngenxa yamandla ayo kunye nokumelana nokugqwala. Njengoko indawo yokunyibilika kwe-titanium iphezulu kakhulu, ifikelela kwiidigri ze-1942, ezingaphezulu kwama-900 degrees kunegolide, inkqubo yokucubungula kunye nokuwelda ngokwemvelo inzima kakhulu kwaye ayinakwenziwa sisityalo esincinci sokucubungula, ngoko ke izitulo ezinamavili ezenziwe nge-titanium-aluminium alloy zibiza kakhulu. Eyokuqala ifanelekile ukusetyenziswa rhoqo kunye neemeko ezilungileyo zendlela kunye nokuqhuba, ngelixa abasebenzisi abayisebenzisa rhoqo, badla ngokufuna ukuyithwala, kwaye badla ngokuqhuba kwimingxunya kunye neendlela ezinamaqhuma banokukhetha isitulo samavili esenziwe nge-titanium-aluminium alloy.

3. Ingxubevange yeMagnesium

I-magnesium alloy isekelwe kwi-magnesium ukuze idibanise nezinye izinto ze-alloy. Iimpawu zayo zezi: uxinano oluncinci, amandla aphezulu, i-modulus ephezulu yokuthamba, ukusasazwa kobushushu okuhle, ukufunxwa kakuhle kwe-shock, ukukwazi ukumelana nemithwalo yempembelelo kune-aluminium alloy, eyona isetyenziswa kakhulu yi-magnesium-aluminium alloy. I-magnesium yeyona ilula kwiintsimbi ezisebenzayo, enobunzima obuthile obumalunga nesibini kwisithathu kune-aluminium kunye nekota yesinyithi, kunye nokusetyenziswa kwe-magnesium kwi iifreyimu zesitulo esinamaviliyenzelwe ukufezekisa "ukukhanya" okungakumbi ngokusekelwe kwi-aluminium.
