Ityhubhu yebhoyila luhlobo lwetyhubhu engenamthungo. Indlela yokuvelisa iyafana netyhubhu engenamthungo, kodwa kukho iimfuno ezingqongqo kuhlobo lwentsimbi esetyenziselwa ukwenza ityhubhu yentsimbi. Ngokwendlela yokusetyenziswa kobushushu, yahlulwe yaba ziintlobo ezimbini zetyhubhu yebhoyila ngokubanzi kunye netyhubhu yebhoyila enoxinzelelo oluphezulu.

Ipropati yoomatshini yetyhubhu yebhoyila sisalathisi esibalulekileyo sokuqinisekisa ukuba intsimbi iyasebenza ngokupheleleyo. Ixhomekeke kulwakhiwo lweekhemikhali zentsimbi kunye nenkqubo yonyango lobushushu. Kwimigangatho yepayipi yentsimbi, ngokweemfuno ezahlukeneyo zokusetyenziswa, kuchazwe iipropati zokutsalwa (amandla okutsalwa, amandla okutsalwa okanye indawo yokutsalwa, ukunwebeka) kunye nobunzima, izalathisi zokuqina, kunye neemfuno zomsebenzisi zobushushu obuphezulu nobuphantsi.

① Ubushushu betyhubhu yebhoyila ngokubanzi bungaphantsi kwama-350℃, umbhobho wasekhaya wenziwe kakhulu ngombhobho ojikeleziweyo oshushu wentsimbi yekhabhoni onguNombolo 10, onguNombolo 20 okanye umbhobho otsalwa kubanda.

(2) Iityhubhu zebhoyila ezinoxinzelelo oluphezulu zihlala zisetyenziswa phantsi kobushushu obuphezulu kunye neemeko zoxinzelelo oluphezulu. Phantsi kwesenzo segesi yolwelo oluphezulu kunye nomphunga wamanzi, i-oxidation kunye ne-corrosion ziya kwenzeka. Umbhobho wentsimbi uyimfuneko ukuze ube namandla aqinileyo aphezulu, ukumelana ne-oxidation ephezulu kunye nozinzo oluhle lwesakhiwo se-microstructure.
