The crystallographic aspects of zinc and zinc-nickel alloys on steel sheets have been studied by means of transmission electron microscopy (TEM) and the O-lattice theory. TEM observation shows that the pure zinc and zinc-nickel hcp η-phase electrodeposits grow epitaxially on α-iron substrates with the Burgers alignment in keeping with the O-lattice theory, although the dimensions of the a-axis and c-axis vary with the Ni content. For the nickel-rich γ-phase, a cube/cube orientation relationship is observed. The relationship can also be interpreted in terms of the O-lattice theory.
