Xa i-forging ifudumala, ixesha lokuhlala lide kakhulu kwiqondo lokushisa eliphezulu, i-oksijini kwisithando somlilo kunye ne-oksijini emphunga wamanzi idibanisa kunye ne-athomu yentsimbi ye-forgings kunye ne-phenomenon of oxidation ibizwa ngokuba yi-oxidation.I-Fusible eyenziwe nge-iron oxide adhesion kumphezulu wesinyithi eyomeleleyo yesikhumba se-oxide, njengokwenza ngaphambi kokususa ukungcola, iya kucinezelwa kumphezulu we-forging, icoceke okanye emva kokuchola, i-sag yokuxobula inxalenye yenziwe.umphezulu wokwakhai-pitting, enzulu xa kusenziwa ubungakanani bejometri, isibonelelo somatshini, okanye isiphumo sokungonelanga kunye nokwenza iindawo ezinobuso obumnyama kwi-scrap, kuya kuba nefuthe ekuchanekeniukufa forgings.

Iindlela zokuthintela i-oxidation zezi:
(1) Nciphisa ixesha lokuhlala kumaqondo obushushu aphezulu xa ukufutha kushushubezwa, qhuba ukufudumeza ngokukhawuleza, kwaye uzame ukusebenzisa indlela yokusebenza yokulayisha okuncinci kunye nokulayisha rhoqo.
(2) gcina umoya we-micro oxidation eziko, unciphise umphunga wamanzi eziko, wenze ubushushu obuncinci be-oxidation okanye ukukhusela unyango lokugquma;
(3) gcina uxinzelelo oluncinci olulungileyo kwiziko lokuthintela umoya obandayo ukuba ungangeni ezikweni.
(4) emva kokuba i-faging forging ishushu, ibrashi, uxinzelelo oluphezulu lwamanzi (uxinzelelo luyi-10Mpa ubuncinane) i-punch okanye ifake i-deformation (ukuba nje kukho i-0.05% ye-structural iron? 0.2% ye-degree of deformation) ukususa oxide isikali.
