The invention provides an ultrasonic non-destructive abrasion-resistant coating thickness and elastic modulus measuring method, which belongs to the technical field of ultrasonic non-destructive detection. The method is based on a pulse echo technology and uses a single immersion focusing probe to acquire an echo signal of an abrasion-resistant coating / metal matrix specimen once to effectively extract longitudinal wave and transverse wave signals of back and forth interfaces of the coating. Spectral analysis is carried out on longitudinal wave and transverse wave signals to acquire corresponding ultrasonic reflection coefficient amplitude spectrum (URCAS).
