Abstract With galvanizing coatings of high strength IF steel as the research object, the microstructure, phase and textures of galvanizing coatings were studied by SEM, EDS and XRD. The orientation relationships between galvanizing coatings and substrate were also analyzed. After galvanizing at 470 ℃ for 120 s, the galvanizing coatings from the inside to the outside are as follows: the compact layer of δ phase, the columnar crystal layer of ζ phase and the small sticks of ζ phase. The main texture components of the columnar crystal layer and small sticks of ζ phase are {010} and {201} plane textures, and the texture strength of columnar crystal layer of the ζ phase is stronger. The main texture components of the compact δ phase are {1010} and {1120} plane textures. The semicoherent interface is formed between {111} planes of the α-Fe and the {1010} or {1120} planes of the δ phase, the {111}〈110〉 and {111}〈112〉 are correspond to the {1010}〈1120〉 and {1120}〈1100〉, respectively. Due to the lower interfacial energy of semicoherent interface, the structure is more stable and the associativity of coatings and matrix is better.
