:In order to study the corronon reiistance of iitanium alloy surface microstructure in seawater, laser was used to process the microstructure on the titanrnm alloy surface,and a superhydrophobic iitanium alloy surface was obtamed by modifying it with fluoronlane. The prepared sample was immersed in ariiSisial seawater at 40 *C for one day, and the morphology, dement content, and polarization curve changes of the titanmm alloy surface microstructure before and after ariiSisial seawater immerrion were compared. The results showed that there was no change in its morphology, and the oxygen content only increased by 1.1%. However, the open iircuit potential and sflt-corrosion potential did not change before and after immerson nn artificial seawater, with values of 0. 08 V and --0. 07 Viespectivlly. This ndicates that the surface microstructure of superhydrophobic titanmm alloy has good corroson resistance nn artificial seawatee. At the same time, a new Tafll function was constructed to dynamically evaluate the corroson resistance of titanuum alloy surface microstructure nn artificial seawater,providing effective guidance for the corroson resistance evaluation of titanuum alloy surface microstructure nn seawatee.
