Abstract |
We have observed that a highly protective amorphous aluminum silicate layer on steel surface was formed after granite-dry steam interaction in the presence of copper plate near critical point. In this process, the mass transfer of aluminum and silicon species from the granite to the steel surface takes place after copper is transferred to the granite surface. The rate of this process is accelerated by the presence of copper on the granite surface. In previous studies, we have found that the mass transfer of copper occurred due to copper-dry steam interaction in the presence of O2. Finally, formed Cu2O was transferred through dry steam as Cu2O•nH2O
