1. Normalizing:
Maitiro ekupisa kupisa umo simbi kana simbi zvikamu zvinopisa kune tembiricha yakakodzera pamusoro peiyo yakakosha point AC3 kana ACM, inochengetwa kweimwe nguva yenguva, uye yozotonhodzwa mumhepo kuti iwane pearlite-yakafanana chimiro.
2. Anealing:
Iyo yekupisa yekurapa maitiro umo hypoeutectoid simbi workpieces inopisa kusvika 20-40 madhigirii pamusoro pe AC3, yakaramba ichidziya kwenguva yakati rebei, yozotonhodzwa zvishoma nezvishoma muchoto (kana kuvigwa mujecha kana kutonhodzwa muraimu) kusvika pazasi 500 madhigirii muchoto. mhepo.
3. Solid solution kupisa kurapwa:
Kupisa kwekurapa maitiro umo iyo alloy inopisa kusvika kune yakanyanya tembiricha uye inochengeterwa pane inogara tembiricha munharaunda imwe chete-chikamu kuti inyungurudze zvakazara chikamu mugadziro yakasimba, uye yobva yakurumidza kutonhora kuti iwane supersaturated yakasimba mhinduro.
4. Kuchembera:
Mushure mekunge iyo alloy yaita yakasimba mhinduro yekupisa kurapwa kana kutonhora kwepurasitiki deformation, zvimiro zvayo zvinoshanduka nenguva kana yaiswa pakamuri tembiricha kana zvishoma pamusoro pekamuri tembiricha.
5. Solid solution kurapwa:
nyungudutsa zvizere zvikamu zvakasiyana-siyana mualloy, simbisa mhinduro yakasimba uye uvandudze kuoma uye kusagadzikana kwemarara, kubvisa kushushikana uye kupfava, kuitira kuti urambe uchigadzira uye kugadzira.
6. Kurapa kuchembera:
Kupisa uye kubata pane tembiricha apo chikamu chekusimbisa chinokwira, kuitira kuti chikamu chekusimbisa chiwedzere uye chiomese, kuvandudza simba.
7. Kudzima:
Nzira yekupisa kupisa iyo simbi inosimbiswa uye yobva yatonhodzwa pamwero wakakodzera wekutonhora kuitira kuti workpiece ipinde isina kugadzikana shanduko yekushandura yakadai semartensite mune zvose kana mukati meimwe nzvimbo yemuchinjikwa.
8. Kupisa:
A kupisa kurapa muitiro umo kudzima workpiece kudziyisa kuti zvakakodzera tembiricha pazasi inokosha pfungwa AC1 kweimwe nguva yenguva, uye ipapo kutonhodzwa uchishandisa nzira inoenderana zvinodiwa kuwana chinodiwa chimiro uye zvinhu.
9. Carbonitriding yesimbi:
Carbonitriding inzira yekupinda panguva imwe chete kabhoni nenitrogen muchikamu chepamusoro chesimbi. Nenzira, carbonitriding inonziwo cyanidation. Parizvino, yepakati-tembiricha gasi carbonitriding uye yakaderera-tembiricha gasi carbonitriding (kureva, gasi yakapfava nitriding) inoshandiswa zvakanyanya. Chinangwa chikuru chepakati tembiricha gasi carbonitriding ndechekuvandudza kuomarara, kupfeka kusagadzikana uye kuneta kusimba kwesimbi. Yakadzika-tembiricha gasi carbonitriding inonyanya kuita nitriding, uye chinangwa chayo chikuru ndechekuvandudza kupfeka kuramba uye kubatwa kwesimbi.
10. Kudzima uye kudzikisira:
Kazhinji itsika kubatanidza kudzimisa uye kupisa kwepamusoro-soro semushonga wekupisa unonzi quenching uye kupisa. Kudzimisa uye kudziya kurapwa kunoshandiswa zvakanyanya munzvimbo dzakasiyana dzakakosha dzezvimiro, kunyanya izvo zvinosungirira tsvimbo, mabhaudhi, magiya uye shafts anoshanda pasi pemitoro inochinjana. Mushure mekudzima uye kudziya kurapwa, iyo yakadzikama sorbite chimiro inowanikwa, uye yayo michina zvimiro zviri nani pane izvo zveyakajairwa sorbite chimiro nekuoma kwakafanana. Kuomarara kwayo kunoenderana nekupisa tembiricha yekupisa uye kune hukama nekudzikama kwesimbi uye kuchinjika-chikamu saizi yebasa rekushanda, kazhinji pakati peHB200-350.
11. Brazing:
Maitiro ekupisa kupisa anoshandisa brazing zvinhu kubatanidza maviri workpiece pamwechete.
