Preparation of laminar α-ZrP nanosheets enhanced Ni[sbnd]W nanocomposite coating and investigation of its mechanical and anti-corrosion properties.

The laminar α-ZrP nanosheets were synthesized through hydrothermal method and were added in the Ni W nanocomposite matrix act as reinforcement. The phase composition, microstructure, elemental composition and chemical circumstances of the composite matrix were analyzed by SEM, EDS, XRD, XPS and AFM. Vickers hardness test, and wear test were used to investigate the mechanical and surface properties of the composite coating. The wear characteristics of the deposited coating are studied in detail. The corrosion resistance of electroplating composite matrix was analyzed by EIS, potentiodynamic polarization and SECM. The testing displayed that the use of α-ZrP to the matrix can enhance the wear resistance, hardness and corrosion resistance of the electrodeposition coating. Among them, the optimal addition of α-ZrP nanosheets was 1 g/L, and the prepared nanocomposite matrix exhibited the excellent friction resistance, and the brilliant impedance value. • The Ni-W/laminar ZrP composite matrix is successfully manufactured via PED technology. • The composite matrix exhibits the brilliant anti-wear and anti-corrosion performance. • The enhancement mechanism of laminar ZrP particles in the alloy matrix has been explored in detail.
