Title: Method and apparatus for ultrasound phased array testing of bearing balls

Abstract

An automated scanning system and method, utilizing specialized dual phased array ultrasonic transducers for producing and detecting Rayleigh waves in ceramic bearing balls are provided for nondestructive, non-contact inspection of ceramic bearing balls. The phased array ultrasonic transducer utilizes a complex curvature configuration that enables the dual phased array ultrasonic transducers to focus ultrasonic energy onto the ball to optimally generate and receive Rayleigh wave signals in the spherical objects.
