Ngaphansi kwezimo zemvelo, ifilimu ye-oxide ye-10-20A izokwakhiwa ebusweni bezingxenye zensimbi ngenxa yokuxhumana nomoya-mpilo emoyeni.Ngesikhathi sokubunjwa kwefilimu yemvelo, kuye ngokuthi izici ezibonakalayo zensimbi ngokwayo, isimo esingaphezulu kanye nezimo ze-oxidation, amanye amafilimu e-oxide akhiwe mancane, amanye aminyene futhi aphelele, kanti amanye akhululekile futhi awaphelele.Ezimweni eziningi, ifilimu yemvelo ye-oxide eyakhiwe ayikwazi ukuvimbela ngokuphumelelayo insimbi ukuthi ingagqwali.
Ziningi izindlela zokwelapha i-oxidation yensimbi, okuhlanganisa i-alkaline chemical oxidation, i-alkali-free oxidation, izinga lokushisa eliphezulu legesi oxidation kanye ne-electrochemical oxidation.Njengamanje, indlela ye-alkaline chemical oxidation isetshenziswa kabanzi embonini.(Futhi indlela ye-acid oxidation)
Izici zefilimu ye-oxide: umbala omuhle, akukho embrittlement ye-hydrogen, ukuqina, ifilimu elincanyana (0.5-1.5um), alinawo umthelela obalulekile kusayizi nokunemba kwezingxenye, futhi libuye libe nomthelela othile ekuqedeni ukucindezeleka okukhiqizwa ngemva kokushisa. ukwelashwa.
Ukwelashwa kokumnyama kuwuhlobo lwendlela yokwelapha i-surface oxidation.Izingxenye zensimbi zibekwe kusisombululo esigxilile kakhulu se-alkali ne-oxidant, sishisiwe futhi sifakwe i-oxidized ekushiseni okuthile, ukuze kwakhiwe ungqimba olufana nolwensimbi oluminyene futhi luhlanganiswe ngokuqinile nesisekelo sensimbi.Inqubo yefilimu ye-ferric oxide ibizwa ngokuthi i-blackening.Ngenxa yethonya lezici ezihlukahlukene ekusebenzeni, umbala wale filimu uhlaza okwesibhakabhaka-omnyama, omnyama, obomvu-obomvu, o-tan, njll.
Inhloso yokwelashwa kokumnyama ikakhulukazi inamaphuzu amathathu alandelayo:
1. Umphumela wokulwa nokugqwala endaweni yensimbi.
2. Khulisa ubuhle nokucwebezela kwendawo yensimbi.
3. Ukushisa ngesikhathi se-blackening kusiza ukunciphisa ukucindezeleka ku-workpiece.
Ngenxa yokuthi ukwelashwa okumnyama kunemiphumela eshiwo ngenhla, izindleko ziphansi, futhi ikhwalithi iphezulu, isetshenziswa kabanzi ekwelapheni kwensimbi ebusweni nokuvimbela ukugqwala phakathi kwezinqubo.
