Design threaded component models and pie and screw test pieces, simulate the use of cable anchorages, and conduct related anti-corrosion technology research. Propose the concept of powder zinc impregnation combined anti-corrosion technology, research and analyze the process methods for long-term anti-corrosion of bridge cable anchorages, conduct composition and metallographic analysis of anti-corrosion zinc impregnation coatings, and design powder zinc impregnation combined anti-corrosion technology. According to the service conditions of the workpiece, carry out process trial production, verify its anti-corrosion performance, study the process parameters of different anti-corrosion levels, so as to meet the anti-corrosion needs of bridge cable anchorages in different service environments.
