Imithombo yamagqabi iyinxalenye ebalulekileyo yenkqubo yokunqunyanyiswa kwesithuthi, inika inkxaso kunye nokuzinza.Ukuze ukwazi ukumelana noxinzelelo oluqhubekayo kunye noxinzelelo olunyamezelayo, imithombo yamagqabi kufuneka iqiniswe kwaye igxininiswe ukuqinisekisa ukuqina kunye nokuphila ixesha elide.Ukuqina kunye nokufudumala ziinkqubo ezimbini ezibalulekileyo ezisetyenziselwa ukuqinisa izinto kunye nokuphucula iimpawu zayo zomatshini.Kweli nqaku, siza kuphonononga iindlela zokucima, ukuthambisa, kunye nokusetyenziswa kwazo ekuqineni nasekufudumeni kwemithombo yamagqabi.
Ukucimayinkqubo ebandakanya ukufudumeza imathiriyeli kwiqondo lobushushu eliphezulu kwaye emva koko ipholise ngokukhawuleza kwindawo engamanzi, efana namanzi okanye i-oyile.Oku kupholisa ngokukhawuleza kubangela ukuba izinto zibe nzima, zandise amandla kunye nokuqina.Xa kufikwa kwimithombo yamagqabi,ukucimangokuqhelekileyo isetyenziselwa ukunyusa ukuqina kwentsimbi, okwenza kube nzima ukunxiba kunye nokukhathala.Inkqubo ethile yokucima esetyenziselwa imithombo yamagqabi ixhomekeke ekubunjweni kwentsimbi kunye neempawu ezifunwayo zemishini.
Emva kwenkqubo yokucima, izinto eziphathekayo ziba nzima kakhulu kwaye zibuhlungu.Ukuze kuncitshiswe le brittleness kunye nokuphucula ubunzima bezinto eziphathekayo, ukufudumala kuyenziwa.Ukufudumeza kubandakanya ukufudumeza into ecinyiweyo kwiqondo lobushushu elisezantsi uze uyipholise ngesantya esiphantsi.Le nkqubo ivumela ukuxinzezeleka kwangaphakathi ngaphakathi kwempahla ukuba kukhululeke, okubangela ukuba kubekho i-ductile kunye ne-brittle material.Ukufudumala kwakhona kunceda ekuphuculeni ukuxhathisa kwezinto kwimpembelelo kunye nokulayisha ukothuka.
Inkqubo yokuqina kunye nokufudumala kwemithombo yamagqabi iqala ngokukhethwa kwe-alloy yensimbi efanelekileyo.I-alloys yensimbi esetyenziswa ngokuqhelekileyo kwimithombo yamagqabi iquka i-5160, i-9260, kunye ne-1095. Ezi ngxube zikhethwa ngenxa yokuqina kwazo okuphezulu, ukuxhathisa ukukhathala, kunye nokukwazi ukumelana nemithwalo enzima.Emva kokuba intsimbi ikhethiwe, ifudunyezwa kwiqondo lokushisa elithile elisekelwe kwi-alloy composition kwaye licinywe kwindawo efanelekileyo ukufezekisa ubunzima obufunwayo.
Ukulandela ukucima, izinto eziphathekayo ziyancipha zibe namandla afunekayo kunye nokuqina.Ubushushu bobushushu kunye nobude bulawulwa ngononophelo ukufezekisa iipropathi ezinqwenelekayo zoomatshini, ezinje ngokuqina, amandla, kunye ne-ductility.Isiphumo sokugqibela sisithombo seqabunga esomeleleyo, esiguquguqukayo, esikwaziyo ukumelana nobunzima bezicelo ezinzima.
Ukuqina kunye nokuqinayemithombo yamagqabi yinkqubo ebalulekileyo efuna ukuchaneka kunye nobuchule.Ukucima okungafanelekanga kunye nokufudumala kunokukhokelela kwimiba eyahlukahlukeneyo, njengokuqhekeka, ukubetha, okanye ubunzima obunganelanga.Ngoko ke, kubalulekile ukulandela iindlela ezingcono zoshishino kunye nokubambelela kumanyathelo okulawula umgangatho ongqongqo ukuqinisekisa ukuba imithombo yamagqabi ihlangabezana neenkcukacha eziyimfuneko.
Ukuqukumbela, ukuqina kunyeukuthambisa kwemithombo yamagqabibadlale indima ebalulekileyo ekuqinisekiseni ukusebenza kwabo kunye nobomi obude.Ukudityaniswa kweenkqubo zokucima kunye nokufudumala kubangela ukuba kubekho into enzima kwaye inzima, eyenza ukuba ifaneleke kakuhle kwiimeko ezixinzelelekileyo eziphantsi kwemithombo yamagqabi.Ngokuqonda iindlela zokucima kunye nokufudumala kunye nokusetyenziswa kwazo ekuqineni nasekufudumeni kwemithombo yamagqabi, abavelisi banokuvelisa umgangatho ophezulu, othembekileyo wamaqabunga amagqabi ahlangabezana neemfuno zezicelo ezahlukeneyo zeemoto kunye nezoshishino.
