This specification establishes the requirements for electrodeposited palladium-nickel (Pd-Ni) coatings for engineering applications. Composite coatings consisting of palladium-nickel and a thin gold over-plate for applications involving electrical contacts are also covered. The classification system for the coatings covered here shall be specified by the basis metal, the thickness of the underplating, the composition type and thickness class of the palladium-nickel coating, and the grade of the gold overplating. Coatings should be sampled, tested, and conform to specified requirements as to purity, appearance, thickness, composition, adhesion, ductility, and integrity (including gross defects, mechanical damage, porosity, and microcracks). Alloy composition shall be examined either by wet method, X-ray fluorescence (XRF), scanning electron microscopy (SEM), energy dispersive spectroscopy (EDS), Auger or electron probe X-ray microanalysis (EPMA), or wavelength dispersive spectroscopy (WDS). Coating adhesion shall be analyzed either by bend, heat, or cutting test.View Less
