The composition of a complex electrolyte for producing nickel coatings with a high molybdenum content has been optimized in this work . It has been shown that the optimal electrolyte composition for producing defect-free coatings containing more than 40 wt .% Mo includes 0 .2 M NiCl₂, 1 .0 M Na₃C₆H₅O₇, 1 g/L saccharin, 1 g/L Na₂MoO₄, a saturated solution of SrMoO₄, and a pH of 9 .0 . Such coatings demonstrate increased corrosion resistance compared to Ni–Mo with lower molybdenum content and Ni–Mo–B, as well as improved electrocatalytic characteristics, confirming their promise as inexpensive cathodes for alkaline electrolysis and a potential alternative to Hastelloy alloys and hard chromium plating .
