Abstract: A non-cadmium multi-layered composite coating is disclosed. Such coating achieves desirable lubricity, retains electrical conductivity, meets high performance industry standards for corrosion resistance, and avoids certain environmental and health hazards. Further disclosed are methods of applying such coating on various substrates using a combination of electrolytic and electro-less plating techniques. Such coating may be advantageously applied in machining and electrical interconnects, and are particularly useful in the defense and consumer electronics and appliances industries.
