The invention discloses integration equipment and a detection method for evaluating
coating bonding strength based on interface
fracture toughness, belonging to the technical field of material
surface engineering. With the equipment, a computer is used for controlling operation of four functional modules, including an
ultrasonic detection module, a
hardness testing module, a continuous press-in testing module and an interface crack detecting module; a man-
machine interactive software system is used for
processing acquisition and transmission of data of the functional modules and analysis operation and
data display and output of an interface press-in mechanical model in an integrated manner; and through ultrasonic
nondestructive measurement on elasticity modulus of a
coating and a matrix and continuous press-in testing on a
coating-matrix interface, quantitative detection on all parameters of an interface
fracture toughness formula is completed in one equipment, and the
critical load PC of coating-matrix interface fracture and the corresponding interface
fracture toughness Kca are obtained. The equipment and the detection principle are clear, the
modular design is beneficial to updating and expanding of a mechanical model
library, and a detection sample is simple and convenient to prepare.
