Njira zopukutira za biphasic steel flanges

1. Pali njira zinayi zopukutira za bi-phasechitsulo flange: Buku, makina, mankhwala ndi electrochemical. Kukana kwa dzimbiri ndi kukongoletsa kwaflangezitha kukonzedwa bwino ndi kupukuta. Madzi opukutira amagetsi omwe alipo achitsulo chosapanga dzimbiri amagwiritsabe ntchito phosphoric acid ndi chromic anhydride. Pakupukuta ndi kuyeretsa, chromium ndi phosphorous zina zimatulutsidwa m'madzi onyansa, zomwe zimawononga chilengedwe.

2. Passivation film idzapangidwa pamwamba pa duplexchitsulo flange, ndipo filimu ya oxide idzayamba kusungunuka. Chifukwa pamwamba microstructure wa duplexchitsulo flangeSizogwirizana, gawo lopindika pang'ono la pamwamba limasungunuka, ndipo kuchuluka kwa kusungunuka kudzakhala kwakukulu kuposa gawo la concave. Kusungunuka ndi kupangidwa kwa nembanemba kumakhala pafupifupi nthawi imodzi, koma ma velocities awo ndi osiyana. Chotsatira chake, kuuma kwa pamwamba pa bi-phase steel flange kumachepetsedwa, zomwe zimapangitsa kuti pakhale malo osalala, owala.
3. Zowonongeka zina zapamtunda monga pores pamwamba ndi zokopa zimatha kudzazidwa ndi kupukuta, kuti muthe kupirira kutopa komanso kukana kwa dzimbiri. Biphase zitsulo flanges ndi kuwirikiza kawiri zokolola mphamvu ya austenitic zosapanga dzimbiri zitsulo, ndipo ali ndi pulasitiki zokwanira ndi kulimba chofunika akamaumbidwe, komanso kupanikizika wapamwamba kukana dzimbiri fracture, makamaka m'madera chloride.
