A study was conducted to examine the effects of selected alloy constituents, particularly copper and iron in greater detail to more closely monitor define their effects on filiform corrosion behavior. Apart from filiform corrosion on painted samples, the corresponding corrosion behavior of unpainted samples was also evaluated to determine whether or not the same effects of alloy constituents on filiform performance were observed on more general corrosion behavior, such as pitting. Painted and unpainted samples were tested. Testing consisted of 6 hours exposure to copper acidified salt spray followed by four weeks at 60 C, 85% relative humidity. After corrosion testing, the unpainted samples were cleaned using the ASTM G1 procedure to remove corrosion products. The results show that the corrosion behavior of unpainted specimens in terms of maximum pit depth exhibit the same general trends as filiform corrosion of painted samples.
