Pob zeb diamond hnav mechanisms txawv ntawm qhov kub thiab txias

Cov kws tshawb fawb siv cov molecular dynamics thiab kev sim corrosion los simulate cov txheej txheem hnav ntawm cov cuab yeej pob zeb diamond. Cov txiaj ntsig tau pom tias pob zeb diamond hnav mechanisms txawv ntawm qhov sib txawv. Thaum qhov kub siab tshaj 1000 K, cov cuab yeej hnav yog tshwm sim los ntawm kev sib pauv ntawm cov pa roj carbon atoms ntawm pob zeb diamond nto nrog hlau atoms hauv cov hlau alloy; Thaum qhov kub thiab txias poob qis dua 900 K, cov cuab yeej hnav feem ntau yog los ntawm nag lossis daus ntawm oxides hauv cov hlau ua haujlwm los ntawm cov tshuaj tiv thaiv oxidation.

Molecular dynamics simulation tau lees paub tias nyob rau hauv qhov kev txiav txim ntawm hlau, cov qauv ntawm pob zeb diamond ntawm lub txiav ntug pib hloov los ntawm lub pob zeb diamond mus rau hexagonal graphite, thiab ces graphitic carbon diffuses rau hlau nto.
