Lub hom phiaj tseem ceeb ntawm kev ntxiv CU thiab P rau05cupcni Weathering Hlauyog txhawm rau txhim kho corrosion tsis kam thiab ntxiv dag zog ferrite los ntawm kev daws teeb meem.
1. CU yog lub ntsiab thiab dav siv alloy keeb los txhim kho atmospheric corrosion tsis kam. Qhov sib ntxiv ntawm CU rau05cupcni Weathering HlauMuaj peev xwm ua tus dense tooj liab oxide nyias txheej nruab nrab ntawm cov hlau txheej ntawm cov hlau thiab cov mecharimulation txheej, yog li inhibit qhov corrosion ntawm nruab nrab rau cov phaj steel.
2. Thaum cov ntsiab lus ntawm CU yog ntau tshaj 0.15%, lub tshuab hluav taws xob daws tsis tau yooj yim. P yog ib qho txiaj ntsig zoo los txhim kho cov atmospheric corrosion tsis kam ntawm alloy ntsiab, thiab yog anode depolarizer. Hauv cov kev daws teeb meem electrolyte, nws tuaj yeem ua kom nrawm qhov kev sib txawv ntawm cov txheej txheem ntawm 05cupcni weathering txheej ntawm 05cupcni weather txheej ntawm kev ua haujlwm corrosion ntawm 05cupcni Weathering Hlau.
3.05 khob huab cua zoo tuaj yeem ua tau raws li cov kev xav tau ntawm cov kev ua yeeb yam ntawm cov ntsiab lus hauv qab 0.2% {% {% raws li qhov qis dua. CR kuj tseem yog ib qho ntawm cov khoom siv alloy txhawm rau txhim kho cov tshuab hluav taws xob ua rau 05cupcni Weather yog pom tseeb tsuas yog thaum CU caij yog sib xyaw ua ke.
4. Nyob rau hauv cov txheej txheem ntawm atmospheric corrosion, cov ntsiab lus ntawm CR yog tswj hwm ntawm 0.30%- 0.45}}%, thiab ni tseem yog ib qho ntawm almoyceric corrosion. Thaum Ni cov ntsiab lus yog 51% thiab CU muaj nyob rau hauv 05cupcni weathering hlau, cov txiaj ntsig ntawm kev txhim kho corrosion tsis pom tseeb.
