Adkeynta dusha birta

Taasi waa, dusha sare waa adag yahay, gudahana waa jilicsan yahay. Deminta soo noqnoqoshada-sare: Geli qalabka shaqada gariiradda-sare ee soo noqnoqda oo ku xidh hadda-soo noqnoqda si aad u kiciso hadda ee qaybta shaqada. Xilliga soo noqnoqda ee sarreeya wuxuu ku urursan yahay dusha sare ee shaqada, sidaas darteed kaliya dusha sare ee shaqada ayaa la kululeeyaa. Deminta ololka: U isticmaal ololka ogsijiinta, acetylene iyo gaasas kale si aad u kululeyso. Kaarburaynta iyo deminta: Si aad u geliso workpiece-ka wakiilka carburizing-ka, wakiilada carburizing adag sida dhuxusha iyo kookaha, wakiilada karburiyeyaasha dareeraha ah sida cyanate potassium, iyo wakiilada gaaska carburizing sida carbon monoxide ayaa loo isticmaalaa in lagu kordhiyo kaarboonka ee dusha birta oo keliya . Waxay ku gaari kartaa qoto dheer milimitir. Nitriding: Waa hab lagu dhex geliyo nitrogen oogada birta. Waxaa jira nitriding gaas ah oo kala furfura ammonia iyo nitriding dareere ah oo aysiidh cyaan ah. Faa’iidada ayaa ah in kuleyliyaha kaliya uusan u baahnayn deminta iyo xanaaqa, iyo heerkulka kuleylka ayaa ka hooseeya kan carburizing, sidaas darteed qaybta shaqada ma noqon doonto mid qallafsan. Khasaaraha ayaa ah in wakhtiga habayntu uu dheer yahay. Nitriding jilicsan (nitrocarburizing) waa habka loo isticmaalo qubeyska milixda leh cyanate (KCNO) oo ah qaybta ugu muhiimsan. Inkasta oo adkaanta la helay aanu ahayn mid sare, wakhtiga daawadu waa gaaban yahay.
