Ngaphantsi kweemeko zendalo, ifilimu ye-oxide ye-10-20A iya kwenziwa phezu kwendawo yentsimbi ngenxa yokudibanisa ne-oksijini emoyeni.Ngethuba lokubunjwa kwefilimu yendalo, kuxhomekeke kwiimpawu ezibonakalayo zetsimbi ngokwazo, umgangatho ophezulu kunye neemeko ze-oxidation, ezinye zeefilimu ze-oxide ezenziwe zincinci, ezinye zixinene kwaye ziphelele, kwaye ezinye zikhululekile kwaye aziphelelanga.Kwiimeko ezininzi, ifilimu ye-oxide yendalo eyenziwe ayikwazi ukuthintela ngokufanelekileyo isinyithi ukuba singagqwali.
Zininzi iindlela zonyango lwe-oxidation yentsimbi, kubandakanywa i-alkaline chemical oxidation, i-alkali-free oxidation, i-oxidation yegesi ephezulu kunye ne-electrochemical oxidation.Okwangoku, indlela ye-alkaline ye-oxidation yeekhemikhali isetyenziswa kakhulu kwishishini.(Kwakhona indlela ye-asidi oxidation)
Iimpawu zefilimu ye-oxide: umbala omhle, akukho hydrogen embrittlement, elasticity, ifilimu encinci (0.5-1.5um), akukho mpembelelo ibalulekileyo kubungakanani kunye nokuchaneka kwamalungu, kwaye inefuthe elithile ekupheliseni uxinzelelo oluveliswa emva kobushushu. unyango.
Unyango olumnyama luhlobo lwendlela yonyango lwe-oxidation yomhlaba.Iindawo zentsimbi zibekwe kwisisombululo esigxininiswe kakhulu sealkali kunye ne-oxidant, ifudunyezwe kwaye ifakwe kwi-oxidized kwiqondo lobushushu elithile, ukwenzela ukuba umaleko we-uniform kunye nomphezulu wesinyithi oshinyeneyo uqulunqwe kwaye uboshwe ngokuqinileyo kwisiseko sesinyithi.Inkqubo yefilimu ye-ferric oxide ibizwa ngokuba yi-blackening.Ngenxa yempembelelo yezinto ezahlukeneyo ekusebenzeni, umbala wale filimu unombala ohlaza okwesibhakabhaka-omnyama, omnyama, obomvu-obomvu, obomvu, njl.
Injongo yonyango olumnyama ikakhulu inezi ngongoma zintathu zilandelayo:
1. I-Anti-rust effect kwi-metal surface.
2. Ukwandisa ubuhle kunye nokukhanya kwendawo yesinyithi.
3. Ukufudumala ngexesha lobumnyama kunceda ukunciphisa uxinzelelo kwi-workpiece.
Ngenxa yokuba unyango olumnyama lunemiphumo ekhankanywe ngasentla, ixabiso liphantsi, kwaye umgangatho uphezulu, usetyenziswa ngokubanzi kunyango lwesinyithi kunye nokuthintela umhlwa phakathi kweenkqubo.
