Ukugalela i-carburizing ngokuchasene ne-nitriding

I-Carburizing kunye ne-nitriding zombini ziinkqubo ezibalulekileyo zokuqinisa umphezulu kwi-metallurgy, kwaye kukho umahluko olandelayo:
Imigaqo yeNkqubo

•I-Carburizing: Kubandakanya ukufudumeza intsimbi ye-carbon ephantsi okanye intsimbi ye-alloy ephantsi kwindawo etyebileyo kwiqondo lobushushu elithile. Umthombo we-carbon uyabola ukuze uvelise ii-athomu ze-carbon ezisebenzayo, ezifunxwa ngumphezulu wentsimbi kwaye zisasazeke ngaphakathi, nto leyo enyusa umxholo we-carbon kumphezulu wentsimbi.
•Ukukhupha i-nitriding: Yinkqubo yokuvumela iiathom zenitrogen ezisebenzayo ukuba zingene kumphezulu wentsimbi kubushushu obuthile, zenze umaleko we-nitride. Iiathom zenitrogen zisabela kwizinto ezidibanisa intsimbi ukuze zenze ii-nitride ezinobunzima obuphezulu kunye nokumelana nokuguguleka okuhle.
Ubushushu beNkqubo kunye nexesha

•I-Carburizing: Ubushushu ngokubanzi buphakathi kwama-850°C nama-950°C. Le nkqubo ithatha ixesha elide, ngesiqhelo iiyure ezininzi ukuya kwezilishumi, kuxhomekeke kubunzulu obufunekayo bomaleko ofakwe kwi-carburing.
•Ukukhupha i-nitriding: Ubushushu buphantsi kakhulu, buqhele ukuba phakathi kwama-500°C nama-600°C. Ixesha lide kodwa lifutshane kunelo lokufaka i-carburizing, lidla ngokuba ngama-avareji ukuya kumakhulu eeyure.
Iimpawu zoMaleko oGxothiweyo

•Ukuqina kunye nokumelana nokunxiba

•I-Carburizing: Ubunzima bomphezulu wentsimbi bunokufikelela kwi-58-64 HRC emva kokugabha, nto leyo ebonisa ubunzima obuphezulu kunye nokumelana nokuguguleka.
•Ukukhupha i-nitriding: Ubulukhuni bomphezulu wentsimbi bunokufikelela kwi-1000-1200 HV emva kokufaka i-nitriding, ephezulu kuneyokufaka i-carburizing, ngokumelana okungcono kokuguguleka.
•Amandla okudinwa

•I-Carburizing: Ingaphucula amandla okudinwa kwentsimbi, ingakumbi xa igobile kwaye idinwe xa ijika.
•Ukukhupha i-nitriding: Ingakwandisa amandla okudinwa kwentsimbi, kodwa isiphumo sibuthathaka kakhulu kuneso se-carburizing.
•Ukumelana nokugqwala

•I-Carburizing: Ukumelana nokugqwala emva kokufakwa kwe-carburizing kuphantsi kakhulu.
•Ukukhupha i-nitriding: Umaleko oxineneyo we-nitride wenziwa kumphezulu wentsimbi emva kokufakwa kwe-nitride, nto leyo enika ukumelana okungcono kokugqwala.
Izinto ezisebenzayo

•I-Carburizing: Ifanelekile kwintsimbi ye-carbon ephantsi kunye nentsimbi ye-alloy ye-carbon ephantsi, kwaye isetyenziswa rhoqo ekwenzeni iigiya, ii-shafts kunye nezinye iindawo ezithwala imithwalo emikhulu kunye nokungqubana.
•Ukukhupha i-nitriding: Ifanelekile kwiintsimbi eziqulethe izinto ezixutyiweyo ezifana ne-aluminium, i-chromium kunye ne-molybdenum. Ihlala isetyenziselwa ukuvelisa iindawo ezichanekileyo nezinganyangekiyo, ezifana neenkuni kunye nezixhobo zokulinganisa.
Iimpawu zeNkqubo

•I-Carburizing

•Iingenelo: Inokufumana umaleko onzulu we-carburised, nto leyo ephucula amandla okuthwala umthwalo weendawo. Inkqubo ilula kwaye ixabiso liphantsi.
• Iingxaki: Ubushushu be-carburizing buphezulu, nto leyo enokubangela ukuguquguquka kwenxalenye ngokulula. Unyango lobushushu olufana nokucima i-carburing luyafuneka emva kwe-carburizing, nto leyo eyandisa ubunzima benkqubo.
•Ukukhupha i-nitriding

• : Ubushushu be-nitriding buphantsi, nto leyo ebangela ukuba inxalenye ingaguquguquki kangako. Ingafikelela kubunzima obuphezulu, ukumelana nokuguguleka okuhle kunye nokumelana nokugqwala. Akukho mfuneko yokucima emva kokukhupha i-nitriding, nto leyo eyenza inkqubo ibe lula.
•Iingxaki: Umaleko one-nitride ubhityile, unomthamo ophantsi wokuthwala umthwalo. Ixesha lokufaka i-nitride lide kwaye ixabiso liphezulu.
