Imithombo yamaqabunga iyingxenye ebalulekile yesistimu yokumiswa kwemoto, ehlinzeka ngokusekela nokuzinza.Ukuze umelane nokucindezeleka nokucindezeleka okuqhubekayo ezikubekezelelayo, iziphethu zamaqabunga zidinga ukuqina futhi ziqiniswe ukuze kuqinisekiswe ukuqina kwazo nokuphila isikhathi eside.Ukuqina nokushisa kuyizinqubo ezimbili ezibalulekile ezisetshenziselwa ukuqinisa izinto futhi kuthuthukiswe izakhiwo zayo zemishini.Kulesi sihloko, sizohlola amasu okucisha, ukuthulisa, kanye nokusetshenziswa kwawo ekuqiniseni nasekufudumeni kwemithombo yamaqabunga.
Ukucishainqubo ebandakanya ukushisa impahla ezingeni lokushisa eliphezulu bese ipholisa ngokushesha endaweni ewuketshezi, njengamanzi noma uwoyela.Lokhu kupholisa ngokushesha kubangela ukuthi izinto zibe lukhuni, zikhulise amandla nokuqina.Uma kukhulunywa ngemithombo yamaqabunga,ukucishangokuvamile isetshenziselwa ukwandisa ubulukhuni bensimbi, okwenza kube ukumelana nokugqoka nokukhathala.Inqubo ethile yokucisha esetshenziselwa iziphethu zamaqabunga incike ekubunjweni kwensimbi kanye nezakhiwo ezifunwayo zemishini.
Ngemuva kwenqubo yokucisha, impahla iba nzima kakhulu futhi ibe brittle.Ukuze unciphise le brittleness futhi uthuthukise ukuqina kwezinto ezibonakalayo, ukufudumala kuyenziwa.Ukushisa kuhlanganisa ukushisisa kabusha into ecishiwe ibe izinga lokushisa eliphansi bese ukuyipholisa ngesilinganiso esiphansi.Le nqubo ivumela ukucindezelwa kwangaphakathi okungaphakathi kokokusebenza ukuthi kukhululeke, okuholela ekubeni kube ne-ductile eyengeziwe kanye nokokusebenza okuncane.I-Tempering iphinde isize ukuthuthukisa ukumelana kwento enomthelela kanye nokulayisha ukushaqeka.
Inqubo yokuqina nokuqina kwemithombo yamaqabunga iqala ngokukhethwa kwe-alloy yensimbi efanele.Ama-alloys ensimbi asetshenziswa kakhulu emithonjeni yamaqabunga ahlanganisa u-5160, 9260, no-1095. Lawa ma-alloys akhethwa ngenxa yamandla awo aphezulu, ukumelana nokukhathala, kanye nekhono lokumelana nemithwalo esindayo.Uma insimbi ikhethiwe, ishiswa ekushiseni okukhethekile okusekelwe ekwakhiweni kwe-alloy bese icinywa endaweni efanele ukuze kuzuzwe ubulukhuni obufunayo.
Ngemva kokucisha, okokusebenza bese kuba namandla adingekayo kanye nokuqina.Izinga lokushisa elipholile kanye nobude besikhathi kulawulwa ngokucophelela ukuze kuzuzwe izici zemishini ezifiselekayo, njengokuqina, amandla, kanye ne-ductility.Umphumela wokugcina uwumthombo wamaqabunga onamandla, oguquguqukayo, futhi okwazi ukumelana nobunzima bezinhlelo zokusebenza ezinzima.
Ukuqina nokuqinayemithombo yamaqabunga kuyinqubo ebucayi edinga ukunemba kanye nobuchwepheshe.Ukucisha okungalungile kanye nokushisa kungaholela ezinkingeni ezihlukahlukene, njengokuqhekeka, ukugoqa, noma ubulukhuni obanele.Ngakho-ke, kubalulekile ukulandela izinqubo ezingcono kakhulu zemboni futhi ubambelele ezinyathelweni eziqinile zokulawula ikhwalithi ukuze uqinisekise ukuthi iziphethu zamaqabunga ziyahlangabezana nezidingo ezidingekayo.
Ekugcineni, ukuqina kanyeukufudumala kwemithombo yamaqabungazidlala indima ebalulekile ekuqinisekiseni ukusebenza kwazo nokuphila isikhathi eside.Inhlanganisela yezinqubo zokucisha kanye nezokuthulisa kubangela into eqinile futhi eqinile, iyenze ifaneleke kahle izimo ezinzima ezithonywa yiziphethu zamaqabunga.Ngokuqonda amasu okucisha nokushisa kanye nokusetshenziswa kwawo ekuqineni nasekufudumeni kwemithombo yamaqabunga, abakhiqizi bangakhiqiza imithombo yamaqabunga esezingeni eliphezulu, enokwethenjelwa ehlangabezana nezidingo zezinhlelo zokusebenza ezihlukahlukene zezimoto nezimboni.
