The autocatalytic deposition of nickel from aqueous electrolytes containing reducing species such as sodium hypophosphite has greatly evolved since its inception in 1946, establishing electroless nickel as a crucial technology across multiple industrial sectors. This study aims to enhance the practical application and longevity of electroless nickel coatings through the continuous regeneration process facilitated by electrodialysis. Employing a systematic approach, we assessed the physical properties and deposition characteristics of nickel-phosphorus alloys under various conditions, emphasizing their superior performance relative to electroplated nickel. Our experimental results demonstrate that the optimized deposition parameters yield coatings with excellent uniformity, enhanced corrosion and wear resistance, and adjustable magnetic properties. Notably, the high-phosphorus electroless nickel coatings found extensive application in rigid memory disks, particularly discerning the necessary correlation between substrate characteristics and coating quality. Ultimately, this research affirms the robust industrial relevance of electroless nickel, revealing opportunities for its application in advanced engineering fields aimed at improving surface performance and durability.
