Title:
CONDUCTOR ROLL FOR ELECTROPLATING
Document Type and Number:
Japanese Patent JPS6046395
Kind Code:
A
Abstract:
PURPOSE:To provide the titled roll low in electric resistance, high in heat conductivity and further strong in corrosion resistance and wear proof property, by successively forming a Cu-plating layer, a Co-Mo-Cr alloy plasma spraying layer and a plasma spraying layer, wherein stainless steel is compounded in a W material, to the under coat surface of a main body. CONSTITUTION:Ni or Ni alloy plating is pref. applied to the surface of the barrel part of a conductor roll main body as under-coat treatment and, thereafter, Cu or Cu-alloy plating is applied to the plating layer in a thickness of about 0.1-10.0mm.. After this plating surface is subjected to blast cleaning, a Co-Mo-Cr alloy is plasms sprayed to the cleaned surface in a thickness of about 1mm.. Subsequently, a plasma spraying layer, wherein stainless steel is compounded in W or a W alloy, is formed to the previous plasma spraying layer by plasma spraying. Finally, the plasma spraying layer of the roll surface is subjected to polishing finish by a cylindrical polishing disc to obtain a conductor roll for electroplating remarkably extended in life.
