I-1. I-chrome ephezulu yentsimbi
I-chrome ephezulu yentsimbi i-iron yentsimbi enesibi se-bib enesixa esiphezulu seChromium. Ngenxa yokongezwa kwe-chromium, i-chromium ephezulu yaphosa i-iron inxibe ngokuchasene nokunganyangeki, ukuxhathisa ubushushu obuphezulu, kwaye isetyenziswe ngokubanzi kwimveliso yoomatshini, oomatshini bokwenza amanzi, kunye namanye amasimi.
I-2. I-SURFSUSE INDLELA YOKUZIPHATHA KWE-CHROIIA YOKUGQIBELA
Ngendlela enobushushu eChromium ephezulu yaphosa i-iron, iindlela ezahlukeneyo ezifana nokuzibandakanya rhoqo, ukucofa kunye nokulandela umlinganiso zihlala zibunjwe ukuze zibubulukhuni kunye namandla ezinto ezibonakalayo.
1. Ngumlilo
Sebenzisa indlela efanelekileyo yonyango, i-chromium ephezulu yentsimbi ifuduselwe rhoqo kubushushu obuphezulu malunga ne-500℃ukufezekisa isiphumo somxholo wezinto ezibonakalayo. I-Othofire inokuphucula amandla kunye nobunzima be-chromiyam ephezulu, kodwa inokukhokelela ekunyukeni kobuhlobo bobuqu ngezinto.
2. Umlilo ophunyelwe
Ukucofa lunyango lwe-chromium ephezulu kwakuqhutywa i-iron kwitanki elikupholayo ukufezekisa ubunzima kunye namandla empahla. Iqondo lokushisa lingaphezulu kwe-800 ne-980 degree, kwaye ukupholisa kufuneka kuthintelwe ngokukhawuleza kakhulu ukuphepha ukugcuma kwinto leyo.
I-3. Ukutsala
Emva kokubanjwa, i-chromium ephezulu yakhutshelwa i-iron ikhutshelwe kubushushu obuthile ukunciphisa ubunzima bezinto kwaye ziphucule ubunzima bayo kunye nexesha. Iqondo lobushushu ngokubanzi lonyango lomlinganiso yi-280 ~ 520 isidanga, kwaye ixesha limalunga ne-1 ~ 3 iiyure.
3. Iziphumo zendlela eyahlukileyo yonyango lwe-chromium ephezulu yentsimbi
Iindlela ezahlukeneyo zokunyanga ubushushu ezibangelwa ziindlela ezahlukeneyo zonyango. Ngenxa yomxholo omkhulu weChromium ophakamileyo, i-chromium ephezulu yaphosa i-iron ye-chromization kwinkqubo yenkqubo yonyango, echaphazela intsebenzo yezinto ezibonakalayo. Ke ngoko, ngaphambi konyango lobushushu, ubushushu onyango olufanelekileyo kunye nexesha kufuneka lukhethwe ukunciphisa impembelelo yengxokezi ye-chrororouth.
Unyango oluqhelekileyo lobushushu lunokuphucula ubunzima kunye namandla ezinto, kodwa ziya kuchaphazela ubunzima kunye nexesha, i-sucture, i-races. Ukunyangwa kunyango kunokuphucula ubunzima kunye namandla ezinto, kwaye kuhlale ucingele ukunyangeka ngokuchasene nokunganyangeki; Kwaye emva kokuba unyango lomlinganiso, ubulukhuni lwezinto ezibonakalayo luyancipha, ukuphucula ubunzima kunye nokungasebenzi, kodwa kunciphisa ukuchasana nokunganyangeki kunye nokunganyangeki kwentolongo.
4. Quma
Iimpawu ze-chromium ephezulu yentsimbi kufuneka inikele ingqalelo kwi-CHROMAPHOEnomenon ngexesha lonyango lobushushu, kwaye ukhethe indlela efanelekileyo yonyango. Different treatment methods such as regular ignition, quenching and tempering determine the hardness, toughness, ductility, wear resistance and corrosion resistance of the material. Kwinkqubo yokusetyenziswa, kuyimfuneko ukukhetha iindlela ezifanelekileyo zonyango ngokwemeko ethile yesicelo ukuqinisekisa ukusebenza kakuhle kwe-chromium ephezulu ye-chromium yaphosa izixhobo zentsimbi.
