Abstract
© 2022 Elsevier B.V.Ti3C2Tx, as a promising material, has attracted extensive attention due to its excellent properties. At the same time, Ce3+ is also a very effective corrosion inhibitor, which can play huge roles in anticorrosion. In this study, Ti3C2Tx-Ce powders were synthesized successfully by doping Ce3+ into Ti3C2Tx powders through a simple reaction. In addition, the Ni-P-Ti3C2Tx-Ce composite coating was synthesized by adding Ti3C2Tx-Ce particles into the Ni-P coating via an electrodeposition technique. Meanwhile, wear resistance performance studies have shown the coefficient of friction (COF) of the Ni-P-Ti3C2Tx-Ce composite coating is about 0.10, which is much lower than that of the Ni-P coating. The wear amount of Ni-P-Ti3C2Tx-Ce composite coating is only about 0.60 mg after 5 min of dry grinding under a load of 5 N and a radius of 5 mm. The microhardness of this composite coating has also been greatly improved, up to 3200 kg·mm−2. Furthermore, electrochemical corrosion behavior studies have shown the corrosion resistance (Rp) of the Ni-P-Ti3C2Tx-Ce composite coating is 120 times higher than that of the Ni-P coating, and 19 times higher than that of the Ni-P-Ti3C2Tx composite coating. The corrosion current of Ni-P-Ti3C2Tx-Ce composite coating is 3 orders of magnitude lower than that of Ni-P coating. Therefore, Ni-P-Ti3C2Tx-Ce coating is a promising material for device surface protection.
