Acoustic micro-imaging tools perform the non-destructive imaging and analysis of internal features (including anomalies and defects) in advanced ceramics and other materials by pulsing ultrasound into the sample and receiving the return echoes.

Various types of polycrystalline diamond (PCD) cutting tool inserts are made from a wafer in which tungsten carbide (WC) serves as a substrate. The PCD provides the hardness and durability that makes cutting possible, while the WC provides a strong base.

An internal structural defect in a ceramic chip capacitor becomes activated when it expands to create an electrical leakage path between two adjacent electrode layers.

A new imaging process can identify extremely small surface or sub-surface cracks in silicon nitride bearing balls.
