This study proposes a bi-layered Ni/Ni-P electrodeposited coating for application in microelectrochemical systems (MEMS). The Ni layer, which possesses high levels of stiffness and toughness, was used as the structural constituent, whereas the Ni-P layer, which demonstrates high levels of hardness and corrosion resistance, served as the surface coating. Therefore, the combined coating demonstrated superior mechanical properties and tunable internal stress capabilities. The Ni-P layer was prepared with pulse plating and consisted of amorphous phase with 14.3wt% P. The DC-plated Ni layer consisted of columnar grains embedded with both twin and dislocation defects. The results of nano-indentation demonstrated that the Ni layer had higher Young's modulus and the Ni-P layer had higher levels of hardness. Finally, the tribocorrosion test in 5% NaCl solution confirmed that the Ni-P layer had superior corrosion and wear resistance to its Ni counterpart.
