Qhov Kev Cuam Tshuam Tsis Zoo ntawm Cov Hlau Stainless Tee Nyob Rau Ntawm Chromium

Txhua cov hlau cuam tshuam nrog cov pa oxygen hauv cov cua ua ib txheej oxide zaj duab xis rau saum npoo. Hmoov tsis zoo, cov hlau oxide tsim los ntawm cov pa roj carbon hlau zoo li qub tseem ua rau oxidize, ua rau lub pob zeb txuas ntxiv mus txuas ntxiv thiab thaum kawg tsim cov qhov. Qhov saum npoo ntawm cov hlau stainless tee tuaj yeem tiv thaiv los ntawm electroplating nrog cov xim pleev xim lossis oxidation-resistant (piv txwv li, zinc, nickel thiab chromium), tab sis, raws li paub, qhov kev tiv thaiv no tsuas yog nyias zaj duab xis. Yog tias txheej tiv thaiv kev puas ntsoog, cov hlau hauv qab pib xeb.

Kev tiv thaiv corrosion ntawm stainless hlau tees nyob ntawm chromium, tab sis vim tias chromium yog ib qho ntawm cov hlau, tiv thaiv txoj kev sib txawv.

Thaum cov nqi ntawm cov chromium ntxiv nce mus txog 10. tsis yog yooj yim. Yog vim li cas yog tias thaum alloying hlau nrog chromium, hom ntawm oxide saum npoo yog hloov mus rau qhov zoo ib yam li cov uas tsim ntawm cov ntshiab chromium hlau. Qhov no nruj khi cov chromium-nplua nuj oxide tiv thaiv lub ntsej muag thiab tiv thaiv oxidation ntxiv. Qhov txheej txheej oxide no tsis tshua muaj nyias, dhau los ntawm qhov koj tuaj yeem pom cov lus ntxig kom zoo ntawm cov nplaim ntawm cov hlau stainless, tee kom cov hlau stainless tee muaj qhov tsis zoo tshwj xeeb. Ntxiv mus, yog tias cov txheej txheej saum npoo av tau raug puas ntsoog, qhov cuam tshuam los saum npoo steel yuav hnov ​​mob nrog cov cua txhawm rau kho nws tus kheej, rov ua cov ntawv no oxide" zaj duab xis passivation", thiab txuas ntxiv ua lub luag haujlwm tiv thaiv. Yog li ntawd, txhua yam stainless hlau tee cov ntsiab lus muaj cov yam ntxwv tsis sib xws, uas yog, cov ntsiab lus chromium yog siab dua 10. 5%.
