Tsib qhov teeb meem tseem ceeb ntawm cov hlau hose

Lub corrosion kuj ntawm stainless hlau hose nyob ntawm cov ntsiab lus ntawm chromium. Thaum qhov sib ntxiv ntawm chromium nce mus txog 10.5 feem pua, qhov atmospheric corrosion kuj ntawm hlau nce ntau, tab sis thaum cov ntsiab lus ntawm chromium siab dua, txawm tias qhov corrosion kuj tseem tuaj yeem txhim kho, nws tsis pom tseeb. Yog vim li cas yog vim li cas thaum alloying hlau nrog chromium, hom oxide nto yog hloov los ua zoo ib yam li cov nto oxide tsim ntawm cov ntshiab chromium hlau. Qhov no nruj me ntsis adhered chromium nplua nuj oxide tiv thaiv saum npoo ntawm oxidation ntxiv. Hom oxide txheej no nyias nyias. Los ntawm nws, koj tuaj yeem pom lub ntuj ci ntawm stainless hlau nto, uas ua rau cov hlau tsis muaj qhov tshwj xeeb nto. Ntxiv mus, yog tias cov txheej txheej saum npoo raug puas lawm, cov hlau tsis zoo yuav hnov ​​​​mob nrog cov cua los kho nws tus kheej, rov ua qhov "passive film" thiab txuas ntxiv ua lub luag haujlwm tiv thaiv.
