unyango ubushushu carburizing

1. Inkcazo: Ukwandisa umxholo wekhabhoni womgangatho ophezulu we-workpiece kwaye wenze i-carbon content gradient kuyo, i-carbon steel ephantsi ifudunyezwa kwaye igcinwe ishushu kwi-carburizing medium kwisithando somlilo, ukuze ii-athomu zekhabhoni zifudumale. ukungena kumphezulu we-workpiece, kwaye emva koko ukucima kuqhutywe. inkqubo unyango ubushushu imichiza.

2. Injongo: ukunyusa umxholo wekhabhoni womgangatho wekhabhoni yentsimbi ephantsi ukuya kwi-0.85-1.10%, kwaye emva koko ucime kunye nobushushu kwiqondo lokushisa eliphantsi ukuphelisa uxinzelelo kunye nokuzinzisa isakhiwo, ukwenzela ukuba umgangatho ophezulu wensimbi unobunzima obukhulu. (HRc56-62) , ukonyusa ukumelana nokunxiba kunye namandla okudinwa. Intliziyo isagcina iplastiki yayo yasekuqaleni kunye nokuqina.

3. Isicelo: I-Carburizing isetyenziselwa ngokubanzi iintsimbi ezinomxholo ophantsi wekhabhoni ezifana ne-15Cr kunye ne-20Cr. Ubunzulu be-carburizing layer buhluke ngokweemfuno zamacandelo, ngokubanzi kwi-0.2 ukuya kwi-2 mm.

Izinto kunye nobunzulu be-carburizing layer bunokukhethwa ngokobungakanani bomsebenzi kunye neemfuno zamandla angundoqo ngexesha loyilo.

Ukukhethwa kobunzulu be-carburized layer kufuneka kuyilwe ngokweemfuno zangempela zokugcina iindleko.

Ukonyuka kobunzulu bomaleko kuthetha ukongezwa kwexesha le-carburizing, kwaye ubunzulu begiya buyilwe ngokubanzi ngokwefomula yobungqina.
