The timely detection of microcracks is of great significance for ensuring the safety of key components. In this paper, colinear wave-mixing technology using the ultrasonic surface wave was applied for the detection of microcracks on metal surfaces. The propagation model of colinear wave-mixing surface wave was first established by the finite element method, and the effect of propagation distance was studied to determine an appropriate observation point to receive signals. The effect of the size of the microcracks on the nonlinear coefficient was then studied. The simulated results show that the nonlinear coefficient decreases with the increasing width of the microcracks and increases with increasing length within a certain range. The results provide a useful reference for the quantitative nonlinear ultrasonic wave-mixing testing of microcracks.
