摘要

The zeolite membrane as a corrosion-resistant membrane has green environmental protection, high-temperature resistance, high-mechanical strength, and other characteristics, which has attracted much attention. However, due to the very different surface properties between metals and inorganics, the embodiment of high-binding force membrane is a major difficulty in the current zeolite membrane synthesis technology. Research has been conducted on the silane (YDH-151)/zeolite (TS-1) composite anticorrosive membrane in Ti-6Al-4V alloy surface, and on the modification effect by using graphene oxide (GO), as well as the membrane formation mechanism after being modified. Scanning electron microscope and 3D laser confocal microscope (3D LCSM) were used to study the effect of GO on the modified silane/zeolite composite anticorrosion membrane, and electrochemical methods, contact angle, bonding force, Fourier transform infrared ray were used to study the modification effect and the membrane formation mechanism and process after being modified. Microscopic observations show that GO causes the zeolite particles to accelerate to accumulate, hinders the lateral membrane formation of TS-1 zeolite which forms thus non-negligible pores or defects. It also reduces the density of the zeolite membrane, and the hydrophobicity and binding force of the composite membrane. However, GO can effectively decrease the corrosion current density and greatly enhance the corrosion resistance of the membrane. YDH-151 undergoes dehydration condensation reaction with metal surface and zeolite, and graft reaction with GO, forming a dense YDH-151/GO/TS-1 composite membrane on the surface of Ti-6Al-4V alloy, with a corrosion resistance rate of 99.8%.
