ukwelashwa ukushisa carburizing

1. Incazelo: Ukuze kwandiswe i-carbon content of the surface layer of the workpiece futhi kwakhiwe i-carbon content gradient ethile kuyo, i-carbon steel ephansi iyashiswa futhi igcinwe ifudumele endaweni yokufihla i-carburizing esithandweni somlilo, ukuze ama-athomu e-carbon. ukungena ebusweni be-workpiece, bese ukucisha kwenziwa. inqubo yokwelapha ukushisa kwamakhemikhali.

2. Injongo: ukwandisa okuqukethwe kwekhabhoni yongqimba olungaphezulu lwensimbi ephansi ye-carbon ku-0.85-1.10%, bese ucisha futhi uthukuthele ekushiseni okuphansi ukuze uqede ukucindezeleka futhi uzinze isakhiwo, ukuze ungqimba olungaphezulu lwensimbi lube nobulukhuni obukhulu. (HRc56-62), khulisa ukumelana nokugqoka namandla okukhathala. Inhliziyo isabambelele epulasitiki kanye nokuqina kwayo kwasekuqaleni.

3. Isicelo: I-Carburizing ngokuvamile isetshenziselwa izinsimbi ezinokuqukethwe kwekhabhoni ephansi njenge-15Cr kanye ne-20Cr. Ukujula kongqimba lwe-carburizing kuhlukile ngokuya ngezidingo zezingxenye, ngokuvamile ku-0.2 kuya ku-2 mm.

Ukujula kwesendlalelo se-material kanye ne-carburizing kungakhethwa ngokuya ngosayizi we-workpiece kanye nezidingo zamandla ezibalulekile ngesikhathi sokuklama.

Ukukhethwa kokujula kongqimba lwe-carburized kufanele kuklanywe ngokwezidingo zangempela zokonga izindleko.

Ukwenyuka kokujula kongqimba kusho ukunwetshwa kwesikhathi sokungcwatshwa kwe-carburizing, futhi ukujula kwegiya ngokuvamile kuklanywa ngokuya ngefomula yokuhlola.
