Chii chinonzi hydrogen yemukati mesimbi yakanyungudutswa neyakanyungudutswa muvira?

Mune grey cast iron, haidrojeni chinhu chinokuvadza, iyo yakaderera zviri mukati, zviri nani. Nekuda kwehuwandu hwekabhoni nesilicon musimbi yakakandwa, kunyungudika kwehydrogen mairi kwakadzikira. Musimbi yakanyungudutswa yakanyungudutswa mucupola, iyo hydrogen zvirimo kazhinji 0.0002 ~ 0.0004%. Musimbi yakanyungudutswa yakanyungudutswa nechoto chekunyunguduka, nekuti chinongedzo chiri pakati pesimbi negasi rechoto idiki, iyo hydrogen yemukati inowanzodzika, ingangoita 0.0002%. Iyo haidrojeni inogadzirwa nekukandira kashoma kukonzeresa porosity uye mapinikoni mukukanda.
