Yuav ua li cas txhim kho cov kev ua tau zoo ntawm tshav kub Resistant Steel Casings
Txhawm rau txhim kho cov oxidation tsis kam ntawm tshav kub resistance ntawm cov kub resistant ntawm tshav kub restings ntawm cov kub, peb tuaj yeem pib ntawm cov hauv qab no:
Alloying cov ntsiab lus ntxiv
Chromium (CR): chromium yog lub ntsiab tseem ceeb los txhim kho oxidation tsis kam. Nws tuaj yeem tsim cov dension chromium oxide tiv thaiv zaj duab xis nyob rau saum npoo ntawm lub casting los tiv thaiv oxygen los ntawm kev sib txawv ntxiv rau sab hauv. Feem ntau, nce cov ntsiab lus chromium rau ntau dua 12% tuaj yeem txhim kho oxidation tsis kam.
Silicon (Si): silicon tuaj yeem txhawb kev tsim ntawm ib qho kev ua yeeb yaj kiab ruaj khov thiab denser oxide zaj duab xis, thiab feem ntau ntxiv 1% {% s silicon tuaj yeem txhim kho cov khoom ua haujlwm antioxidant.
Aluminium (Al): Aluminium muaj kev muaj zog muaj zog nrog oxygen thiab tuaj yeem xum ua daim duab txhuas oxide tiv thaiv zaj duab xis. Ntxiv qhov tsim nyog ntawm txhuas tuaj yeem txhim kho cov oxidation tiv thaiv tshav kub kub, tab sis ntau cov ntsiab lus ntau yuav cuam tshuam rau cov khoom ntawm cov hlau. Nws yog feem ntau tswj tau ntawm 0. 5% {3}}%.
Nto Kho
Txheej txheej thev naus laus zis: Txheej ci xws li ceramic txheej ceramic thiab cov hlau sib xyaw ua ke yog siv rau cov txheej txheem los ntawm cov kab tsuag cua sov thiab tshuaj vapor deposition. Cov txheej txheej no tuaj yeem cais oxygen los ntawm kev sib cuag nrog kev tiv thaiv kev tawm tsam oxidation.
Kev Kho Mob Passivation: Los ntawm cov txheej txheem passive, ib zaj duab xis passting los txhim kho cov npoo ntawm kev tawm tsam Oxidation los txhim kho cov npoo ntawm cov kab mob oling los txhim kho kom txhim kho cov duab nitric, chromic acid thiab lwm yam kev daws teeb meem rau kev kho mob passivation.
Kev tsim kho kom zoo ntawm kev kho cua sov
Kev Kho Mob: Los ntawm kev daws teeb meem siab, cov ntaub ntawv sib txuam tag nrho, uas muaj kev sib xyaw ua ke, uas muaj kev sib xyaw ua ke, uas ua rau muaj kev sib txawv ntawm cov yeeb yaj kiab thiab cov yeeb yaj kiab ntom nti, thiab txhim kho cov khoom antioxidant.
Kev kho mob ruaj khov: Rau cov cua sov resistant prepision particities xws li titanium carbides hauv matrix thiab txhim kho cov ntsiab lus hauv lub siab thiab txhim kho cov oxidation tiv taus.
Tswj Cov Txheej Txheem Ntau Lawm
Kev tswj hwm meej meej: thaum lub sijhawm ua tiav lawm, lub ntsiab lus Alloy yog kom ntseeg tau tias cov ntsiab lus ntawm impurity cov kab mob ua kom ntseeg tau ntawm cov duab.
Txhim kho cov txheej txheem casting: siv cov txheej txheem ua kom nrawm, txhawm rau txo cov kab yees, txhawm rau txo cov oxygen diffusion raws, thiab yog li txhim kho antioxidant cov khoom.
Yog tias koj muaj lus nug lossis xav tau cov ntsiab lus ntxiv ntsig txog kev tiv thaiv kub, peb yuav tiv tauj peb, peb yuav zoo siab pab koj!
