| Abstract | ||||
| Electroless Ni-P coatings use in engineering applications due to its ability to alter and improve the surface properties of the steel substrate. The present study investigates the influence of bath composition, which included nickel sulphate, sodium hypophosphite, and glycine on the deposition rate, coating roughness, and final coating microhardness with using of Taguchi techniqe. The results reveal that final coating roughness and hardness can be optimized by controlling bath composition. The achieved minimum average surface roughness (Ra) was 80.7 nm and the highest coating hardness was 1145 HV. | ||||
