Abstract Scope High-phosphorus nickel is a widely recognized protective coating for metallic parts subject to wear and corrosive environments. The process is autocatalytic, non-line-of-sight, provides uniform coatings to ferrous and non-ferrous surfaces. However, despite the above benefits, nickel plating has a tendency to sporadically flake in oilfield environments, creating challenges to equipment manufacturers, and a need to further improve existing procedures and standards. Increasing interfacial bonding via thermal diffusion is investigated to reduce nickel plating flaking. Specifically, this study evaluates the effects of time and temperature on the interfacial diffusion forming between nickel and 4140 steel plated with high phosphorous-nickel. SEM and EDS analyses reveal that a thin inter-diffusional layer formed and grew over time resulting invariably improved adhesion. Complementarily, micro and indentation revealed changes in hardness and mechanical properties across interfacial layer and plating, while electrochemical tests confirmed the nickel plating corrosion properties only varied slightly in the tested conditions.
