Chitsulo pamwamba kuuma
Ndiko kuti, pamwamba ndi cholimba ndipo mkati mwake ndi ofewa. Kuzimitsa pafupipafupi: Ikani chogwirira ntchito mu koyilo yothamanga kwambiri ndikulumikiza ma frequency apamwamba kwambiri kuti mupangitse pakali pano mu chogwiriracho. Kuthamanga kwapamwamba kwambiri kumayikidwa pamwamba pa workpiece, kotero kokha pamwamba pa workpiece ndi kutentha. Kuzimitsa lawi: Gwiritsani ntchito lawi la okosijeni, acetylene ndi mpweya wina pakuwotha. Carburizing ndi kuzimitsa: Kuyika chogwirira ntchito mu chosungira cha carburizing, ma carburizing olimba monga makala ndi coke, zinthu zamadzimadzi zotsekemera monga potaziyamu cyanate, ndi zopangira gasi monga carbon monoxide zimagwiritsidwa ntchito kuonjezera kaboni pamwamba pachitsulo chokha. . Amatha kufika kuya mu millimeters. Nitriding: Njira yolowetsera nitrogen pamwamba pa chitsulo. Pali mpweya nitriding ndi kuwola ammonia ndi madzi nitriding ndi cynic acid. Ubwino wake ndikuti kutentha kokha sikufuna kuzimitsa ndi kutenthetsa, ndipo kutentha kwa kutentha kumakhala kotsika kuposa kwa carburizing, kotero chogwirira ntchito sichidzapunthwa. Choyipa chake ndikuti nthawi yokonza ndi yayitali. Soft nitriding (nitrocarburizing) ndi njira yogwiritsira ntchito madzi osambira amchere okhala ndi cyanate (KCNO) monga chigawo chachikulu. Ngakhale kuuma komwe kumapezeka sikwapamwamba, nthawi ya chithandizo ndi yochepa.
