Gas-theem oxidation feem ntau yog ua los ntawm qhov kub qis lossis siab siv cua, O2, lossis oxygen-muaj roj (xws li ozone thiab CO2). Nws yog tus cwj pwm los ntawm cov cuab yeej siv yooj yim, tus nqi qis, thiab muaj kuab paug tsawg. Piv nrog rau cov kua -theem oxidation, roj-theem oxidation yog yooj yim dua los siv kev lag luam los ntawm kev tswj xyuas nruj me ntsis xws li lub sijhawm thiab kub. Txawm li cas los xij, nrog rau lub sijhawm thiab qhov kub thiab txias, oxidation etches carbon fibers, ua rau lawv qhov chaw ntog tab sis kuj cuam tshuam rau lawv lub zog tensile. Yog li ntawd, kev tswj xyuas meej ntawm lub sijhawm ua haujlwm thiab qhov kub thiab txias yog qhov tsim nyog kom tsis txhob muaj kev puas tsuaj rau cov pa roj carbon fiber ntau thiab txo qis hauv cov khoom siv sib xyaw ntawm cov khoom sib xyaw.
Ua kua-theem oxidation yuav tsum muab cov pa roj carbon fibers tso rau hauv cov kua tshuaj tiv thaiv kab mob, tso cai rau cov oxidant nyob rau hauv cov kua system los teb cov carbon fibers, yog li etching cov pa roj carbon fiber nto. HNO3, KMnO4, NaOCl, thiab NaClO3 feem ntau siv oxidants. Piv nrog rau cov pa roj-theem kev kho mob, ua kua-theem kev kho mob feem ntau mob me me, tsis ua rau pitting ntau dhau, thiab muaj lub sijhawm ua haujlwm ntev dua, ua rau nws tsim nyog rau kev kawm txog cov txheej txheem ntawm kev kho deg.
Anodizing, tseem hu ua electrochemical oxidation, yog ib txoj kev kho mob uas siv cov pa roj carbon fiber ntau li cov anode thiab siv lub peev xwm rau cov pa roj carbon fiber ntau los tsim cov pa oxygen ntawm nws qhov chaw. Nascent oxygen yog reactive heev thiab tuaj yeem oxidize thiab etch carbon fiber. Cov electrolytes siv hauv anodizing feem ntau suav nrog HNO3, H2SO4, NaCl, KNO3, NaOCl, NH4OH, NH4HCO3, NH4HS, thiab NaOH. Hauv kev tsim khoom tiag tiag, NH4HCO3 cov tshuaj tau dav siv vim nws cov tshuaj tiv thaiv siab thiab tsis muaj zog corrosiveness. Anodizing muaj cov tshuaj tiv thaiv me me, ua haujlwm siab, thiab nrawm thiab sib xws oxidation, ua rau nws haum rau loj- nplai ntau lawm thiab yog li siv dav hauv kev kho cov khoom lag luam carbon fibers. Hauv kev siv tswv yim, cov neeg ua haujlwm feem ntau kho cov khoom kawg ntawm cov pa roj carbon fiber ntau kom ua tau raws li qhov yuav tsum tau ua los ntawm kev hloov hom electrolyte lossis kho qhov tam sim no.
