Resumen
Protective coatings have received considerable attention for the surface treatment of devices. Herein, in situ grown nanoparticles, TiO2 on Ti3C2Tx sheets (TiO2/Ti3C2Tx), are prepared by a simple hydrothermal oxidation method possessing the layer structure, which is applied to prepare protective coatings. The Ni?P?TiO2/Ti3C2Tx coating is prepared by electroplating technology, revealing more excellent properties than those of the Ni?P coating. Compared with the Ni?P coating, even though the Ni?P?TiO2/Ti3C2Tx coating holds the rough surface, the wettability is changed from hydrophilic to hydrophobic, owing to the gathering existence of TiO2/Ti3C2Tx on the surface and coarse surface texture. In addition, the participation of TiO2/Ti3C2Tx in the Ni?P coating can improve the capacity of corrosion prevention and decrease the corrosion rate. According to the results of hardness and wear tests, microhardness of the Ni?P?TiO2/Ti3C2Tx coating is approximately 1350 kg mm-2 and the coefficient of friction (COF) of Ni?P?TiO2/Ti3C2Tx coatings is about 0.40, which is much lower than that of Ni?P coatings. Thus, the Ni?P?TiO2/Ti3C2Tx coating can be a promising material to protect the surface of equipment.
