Decarburization chinhu chakajairika uye chinonetsa chiitiko chinoitika panguva yekupisa kurapwa kwesimbi uye mamwe kabhoni-ine alloys. Rinoreva kurasika kwekabhoni kubva padanho repamusoro pechinhu kana yaiswa kune tembiricha yepamusoro munzvimbo dzinosimudzira oxidation. Carbon chinhu chakakosha musimbi, chinobatsira pakusimba kwayo, kuoma, uye kusapfeka. Naizvozvo, decarburization inogona kutungamira mukudzikiswa kwemagetsi zvivakwa, kuderedzwa kwepasi, uye zvakazara zvigadzirwa zvemhando. Kugadzirisa zvinobudirira decarburization mukupisa kupisa, nzira dzakasiyana-siyana uye nzira dzekudzivirira dzinogona kushandiswa.
1. Kudzora kweAtmosphere
Imwe yedzakanakisa nzira dzekudzikisa decarburization ndeye kudzora mhepo yechoto panguva yekupisa kurapwa. Decarburization inoitika kana kabhoni musimbi inopindirana neokisijeni kana mamwe magasi senge kabhoni dhaikisaidhi, ichigadzira kabhoni monoxide kana kabhoni dhaikisaidhi inobuda kubva pamusoro. Kuti udzivise izvi, inert kana kuderedza mhepo inofanira kushandiswa. Magasi akajairika anosanganisira nitrogen, argon, kana hydrogen, iyo inogadzira nzvimbo isina oxygen, inoderedza njodzi yekurasikirwa nekabhoni.
Mamwe maitiro ekurapa kupisa anoshandisa choto chevacuum kubvisa zvachose kuvepo kwemagasi anogona kuita nepamusoro pesimbi. Iyi nzira inonyanya kushanda kune yakakwirira-yakakosha zvikamu uko kunyange kushoma decarburization isingatenderwi. Nerumwewo, carburizing atmospheres, uko kunoshandiswa kabhoni-rich gasi, inogona kubatsira kuchengetedza kana kuwedzera pamusoro pekabhoni mazinga, kuverengera kungangoita decarburization.
2. Kushandiswa Kwekudzivirira Kuvhara
Kuisa machira ekudzivirira ndiyo imwe nzira yekudzivirira zvinhu kubva ku decarburization. Majasi akadai seceramic paste, copper plating, kana pendi yakasarudzika anogona kuita sezvipingamupinyi zvemuviri, kudzivirira kabhoni kutiza pamusoro. Aya mabhanhire anonyanya kubatsira kune zvikamu zvinotora nguva yakareba yekurapa kupisa kana kune zvikamu zvakaratidzwa kune zvakanyanya oxidative nharaunda.
3. Optimizing Heat Treatment Parameters
Decarburization inotsamira tembiricha, zvichireva kuti iyo tembiricha yakakwira, iyo yakawanda kabhoni inopukunyuka kubva pamusoro pesimbi. Nekunyatsosarudza kupisa kupisa tembiricha uye nguva, njodzi ye decarburization inogona kuderedzwa. Kudzikisa tembiricha yemaitiro kana kudzikisa nguva yekuratidzwa pane tembiricha yakanyanya kunogona kudzikisa huwandu hwekurasikirwa nekabhoni. Mune zvimwe zviitiko, kutonhora kwepakati mukati menguva refu kutenderera kunogona zvakare kubatsira, sezvo kunoderedza iyo yakazara nguva iyo chinhu chinoratidzwa kune decarburizing mamiriro.
4. Mushure-Kurapwa Maitiro
Kana decarburization ikaitika kunyangwe matanho ekudzivirira, mushure mekurapa maitiro akadai sekukuya pamusoro kana machining anogona kushandiswa kubvisa decarburized layer. Izvi zvinonyanya kukosha mumashandisirwo apo zvimiro zvepasi senge kuomarara uye kupfeka kuramba kwakakosha. Mune zvimwe zviitiko, yechipiri carburizing process inogona kuiswa kudzoreredza iyo yakarasika kabhoni muyepamusoro layer, nekudaro kudzoreredza yaidiwa mechanic properties.
Decarburization mukurapa kwekupisa inyaya yakakomba iyo inogona kukanganisa zvakanyanya mashandiro uye kunaka kwezvikamu zvesimbi. Nekudzora mhepo yemuchoto, uchishandisa machira ekudzivirira, optimize maitiro paramita, uye nekushandisa mushure mekurapa nzira dzekugadzirisa, iyo yakashata mhedzisiro ye decarburization inogona kunyatso kuderedzwa. Aya mazano anovimbisa kuti zvinhu zvakarapwa zvinochengetedza simba razvo, kuoma, uye kusimba, pakupedzisira zvichivandudza kunaka kwese kwechigadzirwa chekupedzisira.
