Cov alloy muaj pes tsawg leeg ntawm txhuas anode daim hlau ncaj qha cuam tshuam rau lawv cov kev ua tau zoo thiab kev pabcuam lub neej. Traditional txhuas anode daim hlau feem ntau yog siv binary alloys xws li Pb-Sb thiab Pb-Ca-Sn, tab sis cov alloys muaj teeb meem xws li tus nqi siab corrosion, tsis ruaj tsis khov zaj duab xis, thiab lub neej ua haujlwm luv. Nrog rau kev txhim kho thev naus laus zis, quaternary alloy systems (Pb-Ag-Sn-Bi-Ca) tau maj mam dhau los ua lub hauv paus, uas tuaj yeem txhim kho qhov kev ua tau zoo ntawm cov phaj anode.
Qhov tshwj xeeb alloy muaj pes tsawg leeg (feem pua) yog raws li nram no: Ag: 0.3-0.8%, Sn: 1.0-2.5%, Bi: 0.1-0.5%, Ca: 0.01-0.05%, thiab qhov seem yog txhuas (Pb), nrog rau tag nrho cov ntsiab lus ntawm inevitable impurities Tsawg dua los yog sib npaug rau 0.05% los yog sib npaug rau Fe 0.02%). Txhua lub ntsiab alloying plays lub luag haujlwm tshwj xeeb: nyiaj (Ag) tuaj yeem txhim kho qhov ntom ntom thiab ruaj khov ntawm cov yeeb yaj kiab passive, txo tus nqi corrosion; tin (Sn) txhim khu lub zog txhua yam thiab hnav tsis kam ntawm lub phaj anode; bismuth (Bi) refines cov ciam teb nplej, inhibits intergranular corrosion, thiab prolongs lub neej kev pab cuam; calcium (Ca) ntxiv txhim kho lub zog txhua yam thiab tiv thaiv deformation ntawm anode phaj.
Tsis tas li ntawd, cov ntsiab lus ntawm cov ntsiab lus alloying tuaj yeem hloov kho raws li kev ua haujlwm tiag tiag ntawm electrolytic cell (xws li electrolyte concentration, tam sim no ceev, thiab kev ua haujlwm kub). Piv txwv li, nyob rau hauv siab -tam sim no ceev electrolytic systems, cov ntsiab lus ntawm cov nyiaj thiab tin tuaj yeem tsim nyog ntxiv los txhim kho kev ruaj ntseg ntawm cov yeeb yaj kiab passive. Piv nrog rau cov tsoos binary alloy anode daim hlau, quaternary alloy txhuas anode daim hlau muaj kev pab cuam lub neej nce 1.5 npaug, thiab tam sim no kev ua tau zoo tuaj yeem txhim kho los ntawm 0.5-1%, mus txog ntau dua 90%.
