Kev tiv thaiv kev ua tau zoo ntawm cov yeeb yaj kiab tiv thaiv yog cuam tshuam nrog cov xwm txheej no?
Thaum cov hlau reacts nrog oxygen los yog lwm yam oxidants nyob rau hauv cov huab cua, ib txheej ntawm hlau oxide yuav tsim nyob rau saum npoo ntawm cov hlau. Cov txheej txheej ntawm oxide no cuam tshuam qhov txuas ntxiv ntawm corrosion mus rau qee yam, yog li nws yog hu ua hlau tiv thaiv zaj duab xis.
Kev tiv thaiv kev ua haujlwm ntawm cov yeeb yaj kiab tiv thaiv yog cuam tshuam nrog kev ncaj ncees ntawm cov yeeb yaj kiab, thiab nws kuj tseem cuam tshuam txog seb nws puas ruaj khov rau cov hlau tseem ceeb, txawm tias qhov nthuav dav coefficient zoo sib xws, thiab lwm yam.
Yog hais tias cov oxide yog ntxeem tau, xoob, thiab tsis sib raug zoo nrog tus tswv tsev hlau, cov khoom tiv thaiv ntawm zaj duab xis yuav tsis zoo. Muaj zog, nyias zaj duab xis zoo dua los tiv thaiv cov hlau vim tias cov yeeb yaj kiab zoo li no feem ntau ua rau ntawm cov hlau du, muaj qhov adhesion zoo rau cov hlau, thiab lawv cov thermal expansion coefficients ze dua.
