I-Carburizingkwaye ukukhupha amanziziindlela ezimbini ezisetyenziswa kakhulu zokuqinisa umphezulu kwi-metallurgy. Zombini ziphucula iipropati zomphezulu wentsimbi, kodwa zahlukile kakhulu kwimigaqo yenkqubo, iimeko zokusetyenziswa, kunye neepropati zezinto eziphuma kuyo.
1. Imigaqo yeNkqubo
●Ukufaka iikhabhoritha:
Le nkqubo ibandakanya ukufudumezaintsimbi ye-carbon ephantsi okanye intsimbi ye-alloykwiumoya otyebileyo ngekhabhonikubushushu obuphezulu. Umthombo wekhabhoni uyabola, ukhupheiiathom zekhabhoni ezisebenzayoezisasazeka kumphezulu wentsimbi, zinyusaumxholo wekhabhonikwaye kuvumela ukuqina okulandelayo.
●Ukukhupha i-nitriding:
I-Nitriding iqalisaiiathom zenitrogen ezisebenzayozingena kumphezulu wentsimbi kumaqondo obushushu aphezulu. Ezi athom zisabela kunye nezinto ezidibanisayo (umz., uAl, uCr, uMo) kwintsimbi ukuze zenzeii-nitrides eziqinileyo, okwandisa ubulukhuni bomphezulu kunye nokumelana nokuguguleka.
2. Ubushushu kunye nexesha
| Ipharamitha | I-Carburizing | Ukukhupha i-nitriding |
| Ubushushu | 850°C – 950°C | 500°C – 600°C |
| Ixesha | Iiyure ezininzi ukuya kwezilishumi | Amashumi amabini ukuya kumakhulu eeyure |
Qaphela: Ukufaka i-nitriding kwenzeka kumaqondo obushushu aphantsi kodwa kudla ngokuthatha ixesha elide ukuze kulungiswe umphezulu ngokulinganayo.
3. Iimpawu zoMaleko oQiqisiweyo
Ukuqina kunye nokumelana nokunxiba
●Ukufaka iikhabhoritha:Ifezekisa ubulukhuni bomphezulu58–64 HRC, enika ukumelana nokuguguleka okuhle.
●Ukukhupha i-nitriding:Iziphumo zokuqina komphezulu we1000–1200 HV, ngokubanzi iphezulu kuneendawo ezifakwe i-carburized, kunyeukumelana nokuguguleka okugqwesileyo.
Amandla okudinwa
●Ukufaka iikhabhoritha:Iphucuka ngokuphawulekayoukugoba kunye namandla okudinwa okujijekileyo.
●Ukukhupha i-nitriding:Kwakhona kwandisa amandla okudinwa, nangona ngokubanzikancinci kancincikune-carburizing.
Ukumelana nokugqwala
●Ukufaka iikhabhoritha:Ukumelana nokugqwala okulinganiselweyo.
●Ukukhupha i-nitriding:Iifomumaleko we-nitride oxineneyo, ukubonelelaukumelana nokugqwala okuphezulu.
4. Izixhobo ezifanelekileyo
●Ukufaka iikhabhoritha:
Ilungele kakhuluintsimbi enekhabhoni ephantsi kunye neentsimbi ezine-alloy ephantsiIzicelo eziqhelekileyo ziqukaiigiya, imiphini, kunye nezinto ezisetyenziswayoithwaxwa yimithwalo ephezulu kunye nokungqubana.
●Ukukhupha i-nitriding:
Ilungele iintsimbi eziquletheizinto zokudibanisaezifana ne-aluminium, i-chromium, kunye ne-molybdenum. Ihlala isetyenziselwaizixhobo ezichanekileyo, iimolds, ii-dieskunyeizinto ezinxitywa kakhulu.
5. Iimpawu zeNkqubo
| Umbono | I-Carburizing | Ukukhupha i-nitriding |
| Iingenelo | Ivelisa umaleko oqinileyo onzulu | Isebenza kakuhle emalini Isebenza ngokubanzi Ukuphazamiseka okuphantsi** ngenxa yobushushu obuphantsi Akukho mfuneko yokucima Ubunzima obuphezulu kunye nokumelana nokugqwala |
| Iingxaki | Amaqondo obushushu aphezulu enkqubo anokubangelauphazanyiso Kufuna ukucima emva kokufaka i-carburizing | Ubunzima benkqubo buyanda Ubunzulu bebhokisi engaphantsi Amaxesha amade okujikeleza Ixabiso eliphezulu |
Isishwankathelo
| Uphawu | I-Carburizing | Ukukhupha i-nitriding |
| Ubunzulu beLeya eQinisiweyo | Nzulu | Akukho nzulu |
| Ubunzima bomphezulu | Phakathi ukuya phezulu (58–64 HRC) | Iphezulu kakhulu (1000–1200 HV) |
| Ukumelana nokudinwa | Phezulu | Phakathi ukuya phezulu |
| Ukumelana nokugqwala | Iphantsi | Phezulu |
| Umngcipheko wokuphambuka | Iphezulu (ngenxa yobushushu obuphezulu) | Iphantsi |
| Emva konyango | Ifuna ukucima | Akukho mfuneko yokucima |
| Ixabiso | Ezantsi | Phezulu |
Zombini i-carburizing kunye ne-nitriding zinezibonelelo ezikhethekileyo kwaye zikhethwa ngokusekelwe kwiiimfuno zesicelo, kuqukaumthamo wokuthwala umthwalo, uzinzo olunemilinganiselo, ukumelana nokugugulekakunyeiimeko zokusingqongileyo.
