the corrosion resistance of silver plated carbon aluminum composite with matrices of aluminum alloys in the al-si(1), al-zn-mg(2) and al-mg-si(3) systems was studied. silver plating was performed in a cyanide-thiocyanate electrolyte over a sublayer of nickel and copper precipitated from an ethylene diamine electrolyte. study of microsections showed that delamination of the matrix, pitting at points where carbon fibers protrude, occurs during its preparation and nickeliding, resulting in precipitation of chemical nickel, copper and silver at such defects, with porosity greater than that of the same coatings on uniform surfaces. it is concluded that gool quality coatings on carbon aluminum composites, providing good corrosion resistance and functional properties, can be obtained only if the thickness of the surface layer of aluminum containing no carbon fibers is at least as great as the thickness removed upon preparation for nickeliding, i.e., at least 30 to 40 microns
