Mo uʻamea lafo poʻo le ogaumu eletise faʻafefeteina i totonu o le fale gaosi oloa, o le autu o tekinolosi carburizing o le faʻaaogaina o le sulfur maualalo, maualalo le nitrogen, porosity maualuga.so'o fa'a-carburizing.

Petroleum coking carburizer autu gaosia vaega o Liaoning, Tianjin, Shandong ma isi nofoaga.Faatasi ai ma i latou, o le Liaohe Oilfield o le lalolagi na mafua mai i le maualalo o le sulfur crude oil, o lona uiga o le sulfur i totonu o le suauʻu coke e sili ona maualalo.

Le porosity oso'o fa'a-carburizinge faia foi se sao taua i le carburizing aafiaga ma le absorption fua faatatau o carburizing sooupu.E ala i le faagasologa o le gaosiga, o le pores o le suauu coke carburizing agent e tatalaina uma e faʻateleina ai le vaega faʻapitoa o le carburizing agent, ma o le oloa o loʻo i ai le superpermeability ma e mafai ona vave faʻamavaeina i totonu o le uamea, ina ia faʻateleina le fua o le absorption ma lelei carburizing. .
