Abstract
A method and apparatus for molten salt electroplating a steel member are disclosed, in which the surface of the steel member is activated by anodic treatment and the molten salt electroplating is performed on the activated surface of said steel member.
Claims10
A molten salt electroplating apparatus comprising:
- means for drying and preheating a previously cleaned steel member;
- anodic treatment means for activating the surface of said steel member after it has been preheated;
- iron ion removing means connected to said anodic treatment means and containing a packed layer of metal particles having a greater tendency to ionize than iron;
- and electroplating means including an electroplating zone defined by an unimmersed anode and said steel member and further including a means for introducing a molten salt into said electroplating zone wherein said steel member is electroplated in said electroplating zone after its surface has been activated.
