수용액에서 pH와 일정공급전위 변화에 따른 강철심에 도금된 놋쇠의 안정성을 교류 임피던스로 측정하여 연구하였다. 일정 pH에서 일정공급전위가 양전위로 감에 따라 코팅기공저항은 감소된다. 그 사실은 일정공급전위가 양전위로 감에 따라 도금된 놋쇠층이 용액에 더 용해됨을 나타낸다. 강철심에 도금된 놋쇠의 안정성은 pH
The stability of brass coated on steel cords with pH and applied constant potential changes in aqueous solution has been investigated by AC impedance measurements. In solutions of the constant pH, as a applied constant potential is shifted to positive potential, the coating pore resistance is reduced. The fact indicates that as a applied constant potential is shifted to positive potential, the brass coated is dissolved more in solution. The stability of brass coated on steel cords decrease in the order pH
