Zinthu zosiyanasiyana zomwe zimapanga alloy zimatha kusintha kwambiri makina, kukana kwa dzimbiri ndi microstructure yachitsulo.Ngakhale chromium, faifi tambala, molybdenum, chitsulo akhoza kukhala zinthu zikuluzikulu alloying, zinthu zina monga tungsten, carbon, aluminium, titaniyamu, mkuwa ndi sulfure akhoza kukhala ndi zotsatira kwambiri.Kumvetsetsa zinthu komanso zotsatira zabwino komanso zoyipa pa ma alloys zitha kuthandizira kuzindikira zomwe ma aloyi ena angagwiritsidwe ntchito.
Nickel (Ndi)
Imawonjezera kutentha kwamphamvu, kukana makutidwe ndi okosijeni, nitridation, carburization ndi halogenation.Zimaperekanso kukhazikika kwazitsulo.Kukhalapo kwa chinthu ichi kumathandizira kukana kuchepetsa ma acid ndi caustic komanso kukana kupsinjika kwa dzimbiri.
Chromium (Cr)
Alloying ndi Cr imathandizira kukana kutentha kwa oxidizing ndi sulfidation komanso kukana madera oxidizing ambiri.Ma oxidizing media otere amaphatikizapo nitric ndi chromic acid.Zowonjezera nthawi zambiri zimakhala mu 15 mpaka 30% koma zawoneka ngati 50%.
Molybdenum (Mo)
Kuwonjezera kwa molybdenum kumathandizira kwambiri kukana kwa oxidizing acids monga, hydrochloric (HCl), phosphoric (H3PO4) ndi hydrofluoric acid (HF).Zasonyezedwanso kuti zimagwiritsidwa ntchito popititsa patsogolo kukana kwa sulfuric acid (H2SO4) m'magulu omwe ali pansi pa 60%.Mo imathandizira kukana kutsekereza ndi kugwa kwa dzimbiri komanso kumapereka mphamvu ya kutentha kwambiri.
Chitsulo (Fe)
Izi zimachepetsa mtengo wa aloyi ndikuwongolera kutentha kwa carburizing kukana ndikuwongolera kukula kwamafuta.
Tungsten (W)
Chinthuchi ndi chofanana ndi Mo chifukwa chimapereka kukana kuchepetsa zidulo ndi dzimbiri m'deralo ndikuwonjezera mphamvu ndi kuwotcherera.
Mpweya (C)
Itha kulepheretsa dzimbiri kukana koma imawonjezera mphamvu pakutentha kokwera.
Aluminium (Al)
Zowonjezera za Al zitha kulimbikitsa mapangidwe a aluminiyamu yolimba kwambiri pa kutentha kwakukulu komwe kumakana kuukiridwa ndi okosijeni, carburization ndi chlorination.Kuphatikizana ndi Ti, imalimbikitsanso kuuma kwa zaka muzitsulo zina.
Titaniyamu (Ti)
Monga tafotokozera pamwambapa, zimalimbikitsa kuuma kwa zaka, komanso zimatha kuphatikiza ndi kaboni kuti zichepetse kuwonongeka kwa intergranular chifukwa cha chromium carbide yomwe imapanga pambuyo pa chithandizo cha kutentha.
Mkuwa (Cu)
Imalimbitsa kukana kuchepetsa ma acid.Ma aloyi omwe ali ndi 30 mpaka 40% Cu amapereka kukana kwambiri kumadera onse a HF yopanda mpweya.Ngati Cu iwonjezeredwa ku aloyi ya Ni-Cr-Mo-Fe, kukana kwa hydrochloric, phosphoric ndi kuchuluka kwa sulfuric acid kumawongolera.
Cobalt (Co)
Cobalt imapereka mawonekedwe apadera olimbikitsa ku ma alloys otentha kwambiri.Cobalt imawonjezeranso kukana kwa nickel alloys kuti carburization ndi sulfidation.Izi ndichifukwa choti Co imachulukitsa kusungunuka kwa C mu Ni base alloys komanso chifukwa kusungunuka kwa cobalt sulfide ndikokwera kuposa nickel sulfides, motsatana.
