Measuring the elastic properties of a green ceramic as it is being fired can be difficult and often requires sophisticated non-destructive testing (NDT) techniques. One effective method is called the the impulse excitation technique (IET).
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.
