Abstract
Although a number of suitable methods for plating other metals on aluminum have recently been developed, few researchers have investigated plating on aluminum and its surface roughness. It is also true, today, that it is sometimes necessary to get the surface as smooth as possible, keeping up the initial surface roughness of aluminum basis, as in the case of electroforming industry.
The authors experimented plating on aluminum pretreated by means of zinc immersion method, and examined the surface roughness of basis and plated coatings at each stage of the plating process.
The result is as follows:
If the suitable conditions for plating on aluminum are selected, it is possible to deposite the other metals on aluminum, where the plated coatings show the same surface roughness as that of the aluminum basis.
