摘要： An ultrasonic inspection apparatus includes: an acquisition unit acquiring a signal indicating a fundamental wave and a second harmonic of an ultrasonic wave, which are obtained by the ultrasonic wave being scanned over an inspection object through a medium, at each scanning position; a calculation unit calculating a value obtained by dividing a second harmonic amplitude by a square of a fundamental wave amplitude, at each scanning position; and an output unit outputting information on a defect of the inspection object, based on the value obtained by dividing the second harmonic amplitude by the square of the fundamental wave amplitude.

摘要： A method of manufacturing a composite member including an aluminum member and a resin member that are bonded to each other, the method including: performing blasting on a surface of the aluminum member; modifying the surface of the aluminum member into aluminum hydroxide, the modifying including causing the surface of the aluminum member having undergone blasting to react with water vapor by applying a pressure exceeding an atmospheric pressure; and directly bonding the resin member to the surface of the aluminum member modified to aluminum hydroxide.
