Chikoka Cha Kutentha Kutentha
Pamene mphero zopangidwa ndi nickel-based alloys, kutentha kwakukulu kumapangidwa. Choncho, pokonza makina, gwiritsani ntchito zoziziritsa kukwanira kuti mumize malo odulira, omwe ndi osavuta kupeza odulira mphero yaing'ono, koma pazida zazikulu (monga ocheka kumaso), ndizosatheka kumiza kwathunthu panthawi yodula, ndi chozizirirapo chingathe kuzimitsidwa, pogwiritsa ntchito mphero youma.
Pamene chodulira mphero sichingaphimbidwe ndi choziziritsa, kutentha kumasamutsidwa mwachangu kupita ndikuchokera kuyikapo, zomwe zimapangitsa kuti ming'alu yaying'ono yambiri ikhale yocheperako, ndipo ming'aluyo imakula pang'onopang'ono, ndipo pamapeto pake imachititsa kuti carbide ya simenti iwonongeke. Nthawi zina, chodulira chaching'ono chitha kugwiritsidwa ntchito, ndipo palibe choziziritsa chomwe chimafunikira pakukonza. Ngati chidacho chikudula bwino ndipo moyo wa chida ukuyenda bwino, zikutanthauza kuti mphero yowuma ingathenso kuchitidwa.
Chifukwa chakuti mbali za mafakitale azachipatala ndi zamlengalenga nthawi zambiri zimapangidwa ndi alloys opangidwa ndi nickel, nkhaniyi nthawi zambiri imatsagana ndi zikalata zotsimikizira, momwe kapangidwe kake kazinthu kapadera kameneka kamaperekedwa, kuti tithe kudziwa nthawi yomwe mphero ikukula. zinthu zanji. Zomwe ziyenera kutsatiridwa ndi momwe mungasankhire magawo oyenera odulira ndi njira zodulira molingana ndi kapangidwe kazinthu zotere.
Monga tanena kale, zinthu ziwiri zazikulu za gulu ili lazitsulo ndi faifi tambala ndi chromium. Pamene zitsulo zosungunula zitsulo zimasintha kuchuluka kwa chitsulo chilichonse, katundu wake monga kukana dzimbiri, mphamvu, kuuma, ndi zina zotero, zimasintha, monga momwe zimakhalira.
Kupanga chida chodulira zida zolimba kapena zolimba sizovuta, koma kupanga chida cha alloy cha nickel chomwe chimachita zonsezi sizovuta. Mutha kukhala ndi dzina lanu la ma aloyi awa, koma bola mutadziwa momwe amapangira ndikugwiritsa ntchito chida choyenera, mutha kugaya zinthu ngati Corp20, Rene41, ndi Haynes242 popanda kugunda.
