The (heptadecafluoro-1,1,2,2-tetrahydrodecyl)trimethoxysilane (FAS) is the most auspicious material for corrosion protection application due to its highly hydrophobic and self-cleaning nature. A facile electroless codeposition process was employed to construct a (3-glycidyloxypropyl) trimethoxysilane/graphene oxide/FAS (GPTMS/GO/FAS) coating on AZ91 Mg alloy after hydrolyzing and soaking the substrate in the solution for 12 h followed by drying at 120 degrees C. The presence of graphene oxide (GO) and both silanes developed a more compact, uniform and thick coating on the surface, confirmed by SEM. The investigated electrochemical results revealed that the GPTMS/GO/FAS showed excellent corrosion protection properties with the lowest current density value of 5.03 x 10-10 A cm-2. Moreover, the coating exhibited good mechanical properties (hardness: 52.3 HV & adhesion: 1.34 MPa) and depicted a highly hydrophobic surface (110.4 degrees) which endorsed the remarkable corrosion protection of the AZ91 Mg alloy substrate.
