While WC and Cr3C2-based coatings are known to be suitable materials for low and high temperature, respectively, there is the need to know their behavior at intermediate temperature to make a proper selection in these cases.
The spraying materials were two spherical sintered powders of composition: WC-10CoCr (86/10/4) and NiCr–Cr3C2 (75/25), with a nominal powder size in the range 45±15.

The dispersion characteristic of Lamb wave makes it very complicated to be used in material Nondestructive Testing (NDT).
At present, Lamb wave is mainly used in NDT and evaluation of composite materials and colloform textures etc.
Based on the analysis of frequency dispersion property of multi-mode Ultrasonic Lamb wave, the frequency dispersion curve in the certain material was obtained [2].
