Embodiments of the present disclosure generally relate to enclosures and casings for electronic devices and memory devices, and more particularly to such enclosures and casings having a
nickel-
boron coating and methods for forming such a
nickel-
boron coating. In one embodiment, an article for housing at least a portion of an electronic device is provided, the article comprising a
metal-containing substrate and a layer comprising
nickel and
boron disposed on at least a portion of the
metal-containing substrate, wherein: the amount of nickel in the layer is about 95 wt% or greater based on the total amount of nickel and boron in the layer, and the amount of boron in the layer is about 5 wt% or less. The article has a
thermal conductivity of about 25 W / mK or greater, a
scratch hardness of about 0.5 GPa or greater, a
coefficient of friction of about 0.4 or less, or a combination thereof.
