Ha forgings e futhumatsoa, ​​nako ea bolulo e telele haholo mochesong o phahameng, oksijene e ka seboping le oksijene e mouoane oa metsi li kopana le liathomo tsa tšepe tsa forgings 'me ketsahalo ea oxidation e bitsoa oxidation.Fusible e entsoeng ka tšepe ea oxide e khomaretseng holim'a letlalo la tšepe le tiileng la oxide, joalo ka ho qhekella pele ho tlosa litšila, e ne e tla hatelloa ka holim'a litlolo, e hloekise kapa ka mor'a ho khetha, ho thehoa ha karolo e itseng ea peeling.forging surfacepitting, e tebileng ha ho etsoa boholo ba geometry, tumello ea ho sebetsa, kapa ka lebaka la ho se lekane le ho etsa likarolo tse nang le sefahleho se letšo holim'a sekhechana, ho tla ba le phello ho nepahala hashoa forgings.

Mekhoa ea ho thibela oxidation ke:
(1) fokotsa nako ea ho lula mochesong o phahameng ha forging e futhumala, etsa ho futhumala ka potlako, 'me u leke ho sebelisa mokhoa oa ts'ebetso oa ho kenya le ho kenya khafetsa.
(2) boloka moea o monyane oa oxidation ka seboping, fokotsa mouoane oa metsi ka seboping, ho futhumatsa oxidation e nyane kapa ho sireletsa kalafo ea ho roala,
(3) boloka khatello e nyenyane e ntle ka sebōping ho thibela moea o batang hore o se ke oa kena ka sebōping.
(4) ka mor'a hore lefu la forging le futhumale, borashe, metsi a khatello e phahameng (khatello ke bonyane 10Mpa) punch kapa sebelisa deformation (hafeela ho na le 0.05% ea tšepe ea mohaho? 0.2% ea tekanyo ea deformation) ho tlosa tekanyo ea oxide.
