Paper Abstract

The U and V distortion fields at the interface of cracked zinc alloy ZAS35/carbon steel have been obtained by means of a laser moire interferometry. The optimum cast preheating temperature has been decided based on the experimentally determined shear strength. The microstructure of the interface of bimetal composite of zinc alloy ZAS35/carbon steel is analyzed and studied using X-ray diffraction and Scanning Electron Microscope (SEM). The phase component of the metallic interface bond of the alloy has been determined and the results of interface distribution of elements Fe and Zn have been obtained with dip coating at a temperature of 700°C. The above theory, the experimental technology and the results will be introduced and analyzed in this paper.
