Iimpawu ezibonakalayo kunye neekhemikhali zesinyithi ezisetyenziswayo azinzanga ngokugqithisileyo ngenxa yenani eliphezulu lokungcola kwinkqubo yokwemba. Inkqubo yonyango lobushushu ingabacoca ngokufanelekileyo kwaye iphucule ubunyulu bangaphakathi, kwaye itekhnoloji yonyango lobushushu inokomeleza ukuphuculwa komgangatho wabo kunye nokwandisa ukusebenza kwabo kwangempela. Ukunyangwa kobushushu yinkqubo apho i-workpiece ifudunyezwa kwindawo ethile, ifudunyezwe kwiqondo elithile lobushushu, igcinwe kwelo qondo lobushushu ixesha elithile, ize ipholiswe ngamazinga ahlukeneyo.
Njengenye yeenkqubo ezibaluleke kakhulu ekuvelisweni kwezixhobo, iteknoloji yonyango lobushushu bentsimbi ineenzuzo ezinkulu xa kuthelekiswa nobunye ubugcisa obuqhelekileyo bokucwangcisa. “Imililo emine” kunyango lobushushu bentsimbi ibhekisa ekuthobeni, ekulungiseni, ekucimeni (isisombululo) kunye nokufutha (ukuguga). Xa i-workpiece ishushu kwaye ifikelela kubushushu obuthile, ihlanjululwa kusetyenziswa amaxesha ahlukeneyo okubamba ngokuxhomekeke kubukhulu bomsebenzi kunye nezinto eziphathekayo, kwaye ipholile ngokukhawuleza. Injongo ephambili ye-annealing kukunciphisa ubunzima bezinto eziphathekayo, ukuphucula iplastiki yezinto eziphathekayo, ukuququzelela ukucubungula okulandelayo, ukunciphisa uxinzelelo olushiyekileyo, kunye nokusabalalisa ngokulinganayo ukubunjwa kunye nokulungelelaniswa kwezinto.
Umatshini kukusetyenziswa kwezixhobo zoomatshini kunye nezixhobo zokulungisa iindawo zenkqubo yokucubungula,ukwenziwa kwamalunguphambi nasemva kokucubungula kuya kuba yinkqubo yonyango oluhambelana nobushushu. Indima yayo kuku.
1. Ukususa uxinzelelo lwangaphakathi lwesithuba esingenanto. Isetyenziswa kakhulu kwi-castings, i-forgings, iindawo ezidibeneyo.
2. Ukuphucula iimeko zokucubungula, ukwenzela ukuba izinto eziphathekayo zilula. Njengokuhlanjululwa, ukulinganisa, njl.
3. Ukuphucula iipropathi ezipheleleyo zoomatshini bezinto zetsimbi. Njengonyango lokuthoba.
4. Ukuphucula ubulukhuni bezinto eziphathekayo. Njengokucima, ukucima i-carburizing, njl.
Ngoko ke, ngaphezu kokukhethwa okufanelekileyo kwezinto kunye neenkqubo ezahlukeneyo zokubumba, inkqubo yonyango lokushisa isoloko iyimfuneko.
Unyango lobushushu ngokuqhelekileyo alutshintshi imilo kunye nokwakheka kweekhemikhali ngokubanzi kwendawo yokusebenza, kodwa ngokuguqula i-microstructure ngaphakathi kwendawo yokusebenza, okanye ukutshintsha i-chemical composition of the surface of the workpiece, ukunika okanye ukuphucula ukusebenza kwe-workpiece esetyenziswayo. Ibonakaliswa ngokuphuculwa komgangatho wangaphakathi we-workpiece, ngokuqhelekileyo ingabonakali ngeso lenyama.
