A novel Ni-Co-P alloy coating and Ni-Co-P nanocomposite coating were prepared by jet electrodeposition. The influence of jet electrodeposition processing parameters on the microhardness and wear track width of the Ni-Co-P alloy coating was investigated. Additionally, the cross-section morphology, EDS spectra, XRD patterns, microhardness and wear resistance of the coatings under the optimum jet electrodeposition parameters were evaluated. The BBD analysis results revealed that the established mathematical model was reliable. Furthermore, the optimum Ni-Co-P alloy coating parameters optimized through the response surface method were as follows: jet voltage: 12.14 V, plating solution temperature: 61.60 °C, reciprocating sweep speed: 173.19 mm·s
