Abstract It is important to prepare protective coatings for providing suitable treatments for the device surface. Herein, as a ceramic material, Ti3C2Tx particles are covered with TiO2 and MoS2 particles (Ti3C2Tx@TiO2/MoS2), which are successfully incorporated into Ni-P coatings by the electroplating technique to prepare excellent protective coatings. Compared with the Ni-P coatings, the surface of Ni-P-Ti3C2Tx@TiO2/MoS2 coatings becomes rougher and the wettability has changed from hydrophilic to hydrophobic with increasing the addition of Ti3C2Tx@TiO2/MoS2 particles, due to the gathering of Ti3C2Tx@TiO2/MoS2 particles on the surface and coarse texture. In addition, the result of microhardness for Ni-P-Ti3C2Tx@TiO2/MoS2 coatings can be up to 1050 kgf mm−2, verifying that the incorporation of Ti3C2Tx@TiO2/MoS2 particles can improve the microhardness, which has relation with the additive amount of these particles. As results of electrochemical tests shown, the addition of Ti3C2Tx@TiO2/MoS2 particles can increase the capacity of corrosion prevention and decrease the corrosion rate for the Ni-P coatings. Therefore, the Ni-P-Ti3C2Tx@TiO2/MoS2 coatings can be promising protective coatings.
