The distortional fields of interface-U-field and V-field-have been obtained after the mechanics property for the geometric distortion of interface of cracked zinc alloy ZAS35/carbon steel is analyzed by means of a laser moire interferometry. The optimum cast preheating temperature has been decided in the light of the experiment of shear strength. After the microstructure of interface of bimetal composite of zinc alloy ZAS35/carbon steel is analyzed and studied with a X ray diffraction and an electronic scanning mirror (ESM), the phase component of metallurgical bond of interface of zinc alloy ZAS35/carbon steel has been gained, and the results of interface scan of distribution of elements Fe/Zn have been obtained with the dip coating temperature of 700(C. The above working theory, the experimental technology and its results will be introduced in this paper, and its results will be analyzed.
