Thus, potentiodynamic polarisation tests revealed the Ni plating behaviour with respect to the electroless plating time. For plating times less than 60 s, the plating layer was affected by the substrate microstructure, resulting in a combination of the corrosion characteristics of the substrate and Ni.
Through finite element simulation and experiments, Li metal was found to propagate along the direction perpendicular to the electrode plate and form a linear feature when there is no pressure. Under pressure, lateral growth of lithium plating on the plane of the electrode plate is observed .
Furthermore, the EIS results showed the characteristics of the Ni plating at 60 s, whereas the active polarisation in the potentiodynamic polarisation curve contained a dual loop in the plating layer at 60 s, suggesting an insufficient thickness to act as a plating layer and showing the characteristics of the substrate [ 31 ].
In addition, the galvanic corrosion induced by the Ni plating layer increased the corrosion rate, leading to uniform corrosion on the surfaces of both austenite and ferrite, thus reducing surface pitting. In addition, it accelerated the corrosion rate of the secondary phases.
