Abstract

Terahertz (THz) waves are electromagnetic waves in the frequency range of 0.1 to 10 THz (wavelength of 3000 to 30μm). At present, terahertz technology is widely used in security inspection, temperature sensors, biosensors and other fields. Ceramic coating has the characteristics of high hardness, high wear resistance, high corrosion resistance, etc., and is widely used in many field. However, the damage of the ceramic coating will affect the protective performance of the coating and may even cause damage to the equipment. In this study, the thickness and erosion damage of ceramic coating are measured by terahertz technology. The results show that the terahertz detection technology can effectively detect the coating thickness and erosion damage.
