Abstract

Great potential has been exhibited by MXene (Ti3C2Tx) for improving the anti-corrosion property of polymeric matrixes. However, the anti-corrosion performance of Ti3C2Tx as a filler introduced into silicate bonded ceramic coating in H2SO4, NaOH and NaCl solutions still remains elusive. Herein, the effect of Ti3C2Tx introduction on the contact angle and water uptake of silicate bonded ceramic coatings was illustrated. The anti-corrosion property of ceramic coatings was investigated by using electrochemistry measurements. The results exhibited that the silicate bonded ceramic coating with 1.6 wt% Ti3C2Tx possesses the best anticorrosion in three different solutions respectively. Interestingly, it exhibited the highest impedance modulus (|Z|0.01Hz) of 3.45 × 106 Ω cm2 and the lowest corrosion current density (Icorr) value of 1.18 × 10−8 A/cm2 in the 5 wt% H2SO4 solution. This work also elucidated the anti-corrosion mechanism of Ti3C2Tx reinforced silicate bonded ceramic coating in three different solutions.
