Kev ua haujlwm zoo tshaj ntawm zinc-aluminium-magnesium steel kav nyob rau hauv qhov hnyav hnyav tshwm sim los ntawm cov cim muaj pes tsawg leeg thiab kev sib koom ua ke ntawm lawv cov txheej txheem alloy, tsim lub hauv paus ua haujlwm.Lub hauv paus no suav nrog kev tiv thaiv hluav taws xob, kev tiv thaiv lub cev, thiab tus kheej- cov txheej txheem kho, muab cov kav dej sib xyaw ua ke rau lawv cov txheej txheem kev txhim kho corrosion, kev ua haujlwm dav dav thiab kev siv tshuab. hauv high-kawg engineering thiab ib puag ncig tshwj xeeb.
Lub luag haujlwm tseem ceeb yog qhov tseem ceeb ntawm kev tiv thaiv electrochemical ntawm multi-element alloy txheej. Zinc-aluminium-magnesium steel kav yog coated nrog ternary alloy txheej ntawm zinc, txhuas, thiab magnesium. Zinc ua raws li qhov tseem ceeb sacrificial anode, nyiam reacting nrog oxygen los yog noo noo nyob rau hauv ib puag ncig los tiv thaiv cov hlau substrate los ntawm corrosion. Aluminium ua ib qho kev nruam thiab ntom alumina zaj duab xis hauv txheej, ua kom lub cev muaj zog tiv thaiv dej, oxygen, thiab ion nkag mus. Kev taw qhia ntawm magnesium optimizes microstructure ntawm txheej, txhim kho nws cov tsis kam rau pitting thiab crevice corrosion. Cov nyhuv synergistic ntawm peb lub ntsiab lus hloov kho qhov kev tiv thaiv los ntawm ib qho kev txi rau ib qho anode rau ntau - txheej txheej tiv thaiv, zoo heev txhim kho corrosion kuj kev ntseeg tau.
Qhov thib ob, txheej txheej muaj qhov tshwj xeeb ntawm tus kheej - kho muaj nuj nqi. Thaum qhov chaw raug puas tsuaj vim yog sab nraud quab yuam los yog corrosion, magnesium txhawb kev tsim ntawm magnesium - muaj cov khoom sib txuas los ua kom cov chaw puas thiab tsim cov yeeb yaj kiab tiv thaiv tshiab ntawm cov hlau substrate nto, ua rau qeeb ntawm kev sib kis ntawm sab hauv. Qhov kev kho lub cev muaj peev xwm ua tau zoo txuas ntxiv lub neej kev pab cuam ntawm cov yeeb nkab hauv qhov chaw hnyav, ua rau nws tsim tshwj xeeb rau cov ntawv thov uas muaj kev pheej hmoo ntawm kev puas tsuaj.
Hais txog cov khoom siv kho tshuab, zinc -aluminium-magnesium txheej daim ntawv cog lus ruaj khov rau cov hlau substrate, tuav lub zog qub thiab tawv tawv ntawm cov khoom siv hauv paus, thiab tuaj yeem tiv taus lub zog sab hauv, sab nraud loads, thiab cuam tshuam cov loads. Cov txheej thickness thiab alloy sib piv tuaj yeem hloov kho raws li kev ua haujlwm ib puag ncig kom sib npaug tiv thaiv corrosion thiab nqi. Kev ua tau zoo kuj tau lav; cov yeeb nkab tuaj yeem raug txiav, khoov, welded, thiab threaded kom tau raws li qhov xav tau ntawm ntawm - qhov chaw sib dhos thiab cov qauv tsis sib xws.
Hauv cov ntsiab lus, lub hauv paus ua haujlwm ntawm zinc-aluminium-magnesium steel kav stems los ntawm kev tiv thaiv kev sib koom ua ke, tus kheej - kho cov khoom, thiab zoo heev matrix bonding ntawm zinc, aluminium, thiab magnesium ternary alloy. Cov qauv kev sib koom ua ke no-kev tsim qauv tsim ua lub hauv paus tsim nyog rau nws daim ntawv thov nyob rau hauv ib puag ncig corrosive thiab xav tau ib puag ncig, xav txog kev hloov pauv ntawm cov khoom siv niaj hnub no los tiv thaiv corrosion los ntawm kev tiv thaiv kev tiv thaiv mus rau kev tiv thaiv kev ua haujlwm thiab ntse.
