Blak Ɔksayd vs. Galvanizing .
Di men tin dɛn we difrɛn:
Tiknes: Galvanizing deposits a much thicker layer of zinc, tipikli de frɔm 5 to 25 maykron, usay blak ɔksayd de ad ɔl 1-2 maykron. Dis mek blak ɔksayd fayn fɔ prɛsishɔn pat , we galvanizing bɛtɛ fɔ hevi-duti protɛkshɔn ..
Corrosion Resistance: Galvanizing de gi supia koroshɔn resistans , patikyula na ɔda ɛn harsh ɛnvayrɔmɛnt . Difrɛn frɔm dat, blak ɔksayd nid fɔ de ɔyl ɔ sial ɔltɛm fɔ mek dɛn kɔntinyu fɔ protɛkt di kɔrɛshɔn.

Black Oxide vs. peint .
Di men tin dɛn we difrɛn:
Durability: Blak oksayd de fom wan tin, durable layer we no flake or peel, we de mek i mo wear-resistant pas plenti peint. Peint , na di ɔda say, kin chip ɔ krak ova tɛm, mɔ na ay-stress aplikeshɔn dɛn.
Aesthetic: Blak ɔksayd de gi yunifom, mat blak finish , we yu kin mek glos wit ɔyl ɔ waks. Paint de gi yu bɔku bɔku kɔlɔ opshɔn dɛn bɔt i nɔ kin gi di sem smol, kɔnsistɛns finish.

Blak oksayd vs. anodizing .
Di men tin dɛn we difrɛn:
Material compatibility: Dɛn kin yuz blak ɔksayd fɔs fɔ mek dɛn yuz am wit mɛtal dɛn we gɛt fɛro , lɛk ayɛn ɛn stɛl, usay anodizing na spɛshal wan fɔ aluminiɔm . Dis de mek di tu prɔses dɛn we dɛn kin yuz fɔ difrɛn matirial ɛn industri dɛn.
Koroshɔn protɛkshɔn: Anodizing de gi wan strɔng protɛktiv layt agens kɔrɛshɔn ɛn wear, patikyula fɔ aluminiɔm pat dɛn. Blak ɔksayd nid fɔ gɛt ɔyl ɔltɛm ɔ sial fɔ mek dɛn protɛkt am fayn fayn wan.
Aesthetic and Application: Ɔl tu di prɔses dɛn de gi dɛkɔretiv finish , bɔt anodizing de gi kɔlɔ difrɛns ɛn i fayn fɔ aluminiɔm prɔdak lɛk kɔshɔma ilɛktroniks . Blak Ɔksayd de gi yu wan kɔnsistɛns blak finish , we de mek i fayn fɔ tul ɛn hadwɔd ..
