Electroplated nickel coatings containing second-phase particles are usually applied on the surface of carbon steels to improve corrosion and wear resistance. However, the incorporated particles whether in the form of metallic elements or the form of compounds are often not sustainable, not environmentally friendly, and sometimes not cost-effective. This research is focused on the replacement of common secondary phases with particles that come from agro-waste, as a sustainable material. Cow bone ash particles with a size of 63-75 µm were produced by the calcination of cow bones at a temperature of 800°C. The particles were then incorporated into nickel coatings through an electroplating technique in a Watts solution containing 0-50 g/l CBAp. The surface and cross-section of coatings were studied using SEM, EDS, and XRD techniques. SEM images showed a uniform distribution of the particles in the nickel matrix. The size of incorporated particles was measured to be ten to hundreds of nanometres, much smaller than their initial size. This is probably related to the chemical reaction of the particles with the solution that also caused an increase in the pH of the solution from 4.5 to 5.3-5.7. The results also showed that increasing the particle concentration in the bath up to 25-30 g/l caused an increase in the volume percentage of particles with a maximum value of 4.5 vol%. This also resulted in an increase in the hardness of the nickel coating from 220 HV to around 300 HV. With a further increase in the particle concentration, the particle volume percentage and the hardness of the coating didn’t significantly increase.
