Kev sib piv ntawm corrosion kuj ntawmtitaniumthiab stainless hlau:
1. Titanium yog cov hlau nquag heev, nws cov peev xwm sib npaug yog tsawg heev, thiab nws cov thermodynamic corrosion nyiam nyob rau hauv nruab nrab yog loj. Tab sis qhov tseeb, titanium yog ruaj khov nyob rau hauv ntau yam xov xwm, piv txwv li,titaniumyog corrosion resistant nyob rau hauv oxidizing, nruab nrab, thiab tsis muaj zog txo xov xwm. Qhov no yog vim titanium muaj kev sib raug zoo nrog oxygen. Nyob rau hauv cov huab cua los yog oxygen-muaj nruab nrab, ib tug ntom, muaj zog adhesion thiab inert oxide zaj duab xis yog tsim nyob rau hauv titanium nto, uas tiv thaiv titanium matrix los ntawm corrosion. Txawm tias vim muaj kev siv tshuab, nws yuav rov qab los yog rov tsim dua sai. Qhov no qhia tiastitaniumyog ib tug hlau nrog ib tug muaj zog passivation nyiam. Cov oxide zaj duab xis ntawm titanium khaws cov yam ntxwv no thaum nruab nrab kub qis dua 315 degree.
2. Lub corrosion kuj ntawm stainless hlau feem ntau nce nrog cov ntsiab lus chromium. Lub hauv paus ntsiab lus yog tias thaum muaj cov chromium txaus nyob rau hauv cov hlau, ib tug nyias thiab ntom oxide zaj duab xis yog tsim nyob rau saum npoo ntawm cov hlau, uas yuav tiv thaiv tau ntxiv oxidation los yog corrosion. Lub oxidizing ib puag ncig tuaj yeem ntxiv dag zog rau cov yeeb yaj kiab no, thaum qhov kev txo qis ib puag ncig yuav inevitably rhuav tshem cov yeeb yaj kiab no, ua rau corrosion ntawm hlau.
