Abstract:

Porous metal coatings are produced by multi-step electrodeposition method involving application of higher current density at lower duration and lower current density for longer durations. During higher current step, the evolved hydrogen bubbles serve as the self-collapsing templates to deposit the metal ions and during lower current density at longer duration step, the coating is applied to improve the bond strength. The multi-step depositions by alternating these steps provides the development of more complex porous structures that can have desired interconnectivity between the pores and have desired morphology, and desired wettability and wickability characteristics, and have a good bond strength between the coated layers as well as coated layers and the base substrate.
