Cov tshuaj tiv thaiv molybdenum electrode nrog cov khoom hauv iav
Molybdenum electrodeshnov mob nrog qee yam khoom lossis impurities hauv cov iav muaj pes tsawg leeg ntawm qhov kub thiab txias, ua rau muaj kev cuam tshuam loj heev rau cov electrodes. Piv txwv li, iav kev daws teeb meem siv As2O3, Sb2O3, thiab Na2SO4 ua kom pom tseeb corrode molybdenum electrodes heev thiab yuav oxidized rau hauv MoO thiab MoS2.
Electrochemical cov tshuaj tiv thaiv hauv iav electrofusion
Cov tshuaj tiv thaiv electrochemical tshwm sim hauv iav electrofusion ntawm kev sib cuag ntawm molybdenum electrode thiab molten iav. Thaum lub sij hawm zoo ib nrab voj voog ntawm AC fais fab mov, qhov tsis zoo oxygen ions hloov mus rau qhov zoo electrode tso tawm electrons, thiab cov electrons tso oxygen, ua rau oxidation ntawm molybdenum electrode.
Thaum lub sij hawm tsis zoo ib nrab voj voog ntawm AC fais fab mov, qee cov cations (xws li boron) hauv cov iav yaj yuav txav mus rau qhov tsis zoo electrode thiab tsim cov molybdenum electrode tebchaw. Cov tebchaw no tau xoob tso rau ntawm qhov chaw electrode thiab ua rau cov electrode puas.
Kub thiab ceev tam sim no
Tus nqi yaig ntawm molybdenum electrodes nce nrog nce kub. Thaum cov iav muaj pes tsawg leeg thiab cov txheej txheem kub yog qhov ruaj khov, qhov ceev tam sim no dhau los ua qhov tseem ceeb tswj tus nqi electrode corrosion. Txawm hais tias qhov siab tshaj plaws tam sim no qhov ceev ntawm molybdenum electrodes tuaj yeem ncav cuag 2 ~ 3A / cm2, yog tias ua haujlwm loj tam sim no, kev yaig ntawm cov electrode yuav nce ntxiv.
