Ibhola yentsimbi ethwala iibheringi yibhola yentsimbi eqhelekileyo yemizi-mveliso esetyenziselwa ukuhambisa iindawo kwiibheringi nakwezinye izixhobo zoomatshini. Ineempawu zokuba namandla aphezulu, ubulukhuni kunye nokumelana nokuguguleka, ngoko ke ulawulo ngokwenkqubo kunye nesiphumo lubaluleke kakhulu. Oku kulandelayo kuza kwazisa inkqubo yonyango lobushushu kunye nesiphumo seebhola zentsimbi ezithwala iibheringi.
Unyango lobushushu lubhekisa kuthotho lweenkqubo zobuchwepheshe ngokufudumeza nokupholisa izixhobo ukutshintsha isakhiwo kunye neempawu zezinto. Inkqubo yonyango lobushushu yeebhola zentsimbi ezithwalayo idla ngokubandakanya amanyathelo anjengokufudumeza, ukucima kunye nokurhangqa.
Ukufudumala yinkqubo yokufudumeza ibhola yentsimbi ecinyiweyo ukuya kubushushu obuthile, uze uyipholise ngexesha elifanelekileyo. Injongo yokufudumala kukususa uxinzelelo lwangaphakathi oluvela ngexesha lokucima, ukunciphisa ukuqhekeka, kunye nokuphucula ukuqina kunye nokuqina. Ubushushu kunye nexesha lokufudumala ngokubanzi zimiselwa ngokwendlela ethile kunye neemfuno zebhola yentsimbi ecinyiweyo. Ubushushu bokufudumala buphantsi kakhulu okanye ixesha lifutshane kakhulu, kunokukhokelela ekwandeni koxinzelelo olushiyekileyo, ukufudumala okunganelanga, kuchaphazele ukusebenza kwebhola yentsimbi ecinyiweyo; Ubushushu bokufudumala buphezulu kakhulu okanye ixesha lide kakhulu, kuya kunciphisa ubunzima kunye nokumelana nokuguguleka. Ke ngoko, ulawulo lwenkqubo yokufudumala lubaluleke kakhulu.
Okwesibini, ukucima yinkqubo ephambili yonyango lobushushu bebhola yentsimbi ethwalayo, ngokufudumeza ibhola yentsimbi ethwalayo ukuya kubushushu obubalulekileyo, ize iphole ngokukhawuleza, ukuze ihlelwe ibe yi-martensite okanye i-bainite. Ukucima kunokuphucula ubulukhuni kunye namandla ebhola yentsimbi ethwalayo, kwandise ukumelana kwayo nokuguguleka kunye nobomi benkonzo. Indawo yokupholisa kwinkqubo yokucima idla ngokuba yioyile, amanzi okanye igesi, kwaye indawo yokupholisa efanelekileyo ikhethwa ngokweemfuno ezithile zebhola yentsimbi ethwalayo. Ubushushu bokucima, isantya sokupholisa kunye nokukhethwa kwendawo yokupholisa kuya kuba nefuthe elibalulekileyo kwisakhiwo kunye nokusebenza kwebhola yentsimbi ethwalayo. Ubushushu obuphezulu kakhulu okanye isantya sokupholisa esikhawulezayo sinokukhokelela kwiintanda kunye nokuguquguquka; Ubushushu buphantsi kakhulu okanye isantya sokupholisa sicotha kakhulu, nto leyo eya kuchaphazela ubulukhuni kunye namandla.
I-Carburizing yinkqubo eqhelekileyo yokuqinisa umphezulu, ngokufaka ibhola yentsimbi ethwalayo kwi-compound equlethe izinto zekhabhoni ukuze kufudunyezwe ukufudumeza, ukuze izinto zekhabhoni zingene kumphezulu webhola yentsimbi, zonyuse ubulukhuni bayo kunye nokumelana nokuguguleka. Ubushushu, ixesha lenkqubo ye-carburizing kunye nokukhethwa kwendlela ye-carburizing kunefuthe elibalulekileyo kubukhulu kunye nobunzima bomaleko we-carburizing. Ubushushu obuphezulu kakhulu okanye ixesha elide kakhulu kunokukhokelela ekuqhekekeni, ubushushu obuphantsi kakhulu okanye ixesha elifutshane kakhulu kuya kuchaphazela umgangatho kunye nefuthe komaleko we-carburizing.
Isiphumo sonyango lobushushu lweebhola zentsimbi ezithwalayo sihlala sivavanywa zizibonakaliso ezithile zokusebenza, ezinje ngokuqina, ukumelana nokuguguleka, ukuqina njalo njalo. Isiphumo sonyango lobushushu esifanelekileyo kufuneka sibe bubunzima obuphakathi, ukumelana nokuguguleka okuhle, kunye nokuqina ukuqinisekisa ubomi kunye nokuthembeka kwebhola yentsimbi ethwalayo ngexesha lokusetyenziswa.
Ukulungiswa nokulawulwa kweenkqubo zonyango lobushushu kunye neziphumo kufuna izixhobo kunye netekhnoloji ephucukileyo, kunye nabaqhubi abanamava. Kwimveliso yokwenyani, kuyimfuneko ukulungelelanisa nokuphucula ngokweemfuno zezinto ezithile kunye neenkqubo ukuqinisekisa ukuba umgangatho kunye nokusebenza kweebhola zentsimbi ezithwalayo kuyahlangabezana nemigangatho kunye neemfuno zabathengi.
