Description

Ceramic materials keep high strength under high temperature and nonlubricative environments. Ceramic bearing balls are more commonly used now to replace steel bearing balls to sustain high loads under such hostile environments. However, because ceramics are brittle, surface defects of ceramic bearing balls can cause total mechanical failure of the whole mechanism. In this paper, we shall discuss a quick, efficient, and accurate method for performing nondestructive testing of spherical objects. Currently, there are several techniques being used to inspect spherical objects. Here, we introduce a new noncontacting technique, the optical probing technique of spherical resonance. This technique has great potential in the surface defect inspection of spherical objects.

Optical probing of spherical resonance applied to surface defect inspection
