| Abstract Scope |
High-temperature corrosion of metallic surfaces and equipment is an issue in many industries. This work focuses on the fabrication and evaluation of passive wireless inductor-capacitor (LC) sensors for oxidative corrosion of metals at high temperatures. LC resonators were fabricated via screen printing using metal- and electroceramic-based inks on dense polycrystalline alumina (Al2O3) substrates. The LC design was modeled using ANSYS HFSS, with the LC passive wireless sensors operating at frequencies from 70-100 MHz. The wireless response of the LC was interrogated and received by a vector network analyzer at temperatures from 50-800 °C in real-time. A copper (Cu) 110 surrogate substrate was initially used to demonstrate the technology. The copper (Cu) substrates were characterized by TGA analysis while SEM characterized the microstructures of both the LC sensor and oxide layer. The fabricated sensors demonstrate simultaneous temperature and corrosion measurements in real-time, accurately measuring oxide growth and cracking events. |
