Muaj plaub hom kev tiv thaiv kev tiv thaiv hlau, xws li tswj cov khoom siv nws tus kheej, qhov chaw siv, qhov nruab nrab ntawm cov khoom thiab qhov chaw, thiab tsim cov qauv kho cov hlau. Yog hais tias tagnrho corrosion-resistant alloy yog siv los ua cov ntsia hlau, nws yog kev lag luam tshwj tsis yog muaj tshwj xeeb kev xav tau. Nws tsis zoo los ntawm qhov pom kev, los yog kom muab cais tawm ntawm lub hau los ntawm tej yam xwm txheej uas ua rau muaj corrosion, thiab nws tsis yog siv rau kev xyaum. Tej zaum nws yuav nyuaj heev. Kev txhim kho cov qauv zoo nkauj tuaj yeem txhim kho cov kev cuam tshuam ntawm cov xwm txheej tshwj xeeb hauv qee yam, tab sis tus qauv ntawm cov feem pua tsis tuaj yeem hloov siab thiab nws txoj kev tiv thaiv tsis ruaj khov. Yog li no, txoj kev no tsis tsim nyog kho qhov teeb meem, tsuas yog kev tiv thaiv kev tiv thaiv. Ya dej, los yog qhov chaw tswj qhov deg, yog tam sim no txoj kev siv ntau tshaj plaws.
Kev kho cov duab ntxaum los ntawm kev siv ntau txoj kev los siv cov txheej txheem tiv thaiv rau ntawm cov hlau, nws lub luag hauj lwm yog cais cov hlau tawm ntawm qhov chaw hauv corrosive kom tsis zoo rau cov txheej txheem corrosion, los yog txo cov kev sib cuag ntawm corrosive medium nrog hlau nto, thiab tiv thaiv los sis txo qhov laj thawj ntawm kev xeb hluav taws. Cov txheej txheem tiv thaiv yuav tsum muaj peev xwm ua tau raws li cov hauv qab no: 1. Kev sib deev tsis sib xws, hnyav hnyav, hnyav siab, 2. Lub tsev yog cov lus cog, ua tiav, lub qhov me me, 3. Sab nraud nrog cov xim hlau, zoo adhesion, qee yam tuab. Cov txheej txheem tiv thaiv feem ntau yog muab faib ua ob hom: hlau txheej thiab non-hlau txheej. Hlau txheejtxheem yog siv cov hlau lossis cov hlau uas muaj kev tivthaiv corrosion los tiv thaiv txheej txheem tiv thaiv rau ntawm qhov yooj yim corrodible hlau nto. Hom txheej no kuj yog hu ua plating. Muaj ntau txoj kev thiab ntau hom hlau plating, feem ntau yog plating, ua raws li kev rho tawm hlau (kub dip) thiab tshuaj kho deg.
Cov xim uas tsis yog xim hlau yog hais txog kev siv cov khoom siv organic polymer xws li cov xim thiab cov ntaub ntawv pov thawj xws li khoom siv los ua cov txheej txheem tiv thaiv rau ntawm cov khoom siv hlau lossis qhov chaw. Cov txheej txheem tiv thaiv tau tuaj yeem tswj cov hlau los ntawm qhov nruab nrab ntawm kev tiv thaiv thiab tiv thaiv cov hlau los ntawm kev sib tiv tauj corrosion. Corrosion los ntawm nruab nrab
