MORPHOLOGY AND CRYSTALLOGRAPHY OF HCP ZN CRYSTALS ELECTRODEPOSITED ONBCC FE-3-PERCENT-SI SINGLE-CRYSTAL SUBSTRATES

The morphology and crystallography of Zn crystals electrodeposited on Fe-3mass%Si ferrite single crystal substrates were examined for variou s substrate orientations. The epitaxy between the Zn crystals and the ferrite substrates exists on both polycrystalline and single crystal s ubstrates. Zn crystals deposited on the (100)(b), (110)(b) and (111)(b ) substrates have four, one and three variants of the habit plane, res pectively, fn crystals on the (510)(b) substrate exhibit more than two variants of the habit plane. Zn crystals deposited on the (110)(b) su bstrate have the Burgers orientation relationship with the substrate. The morphology and crystallography of Zn crystals can be explained by the formation of invariant lines on the microscopic {110}(b) facets of etch pits formed prior to the deposition.
