Abstract

PURPOSE: To improve corrosion inhibitive and adhesive properties as well as resistance against the peeling-off of an end surface by sandwiching a viscoelastic resin with a metal having an evaporated Al/Al alloy plated layer at the bottom of the surface and an SiOx layer at the top.
CONSTITUTION: An evaporated Al/Al alloy plated layer is formed as a bottom layer on the surface of a metal plate. Thus the corrosion inhibitive properties of the metal plate are enhanced. In this case, an evaporated Al alloy plated layer of Cr can be formed as a substitute for the evaporated pure Al plated layer. In addition, a required amount of the applied plating is approx. 5g/m2 min. The Al/Al alloy plated layer is protected against an corrosive environment by providing SiOx as the top layer of the metal-plated surface. The preferable thickness of this SiOx film is approx. 0.5μm min. The viscoelastic resin of polystyrene is sandwiched with this metal plate.
