Novel Sensors for Harsh­Environment Energy Generation

PI: Jon Longtin

Direct-Write Thermal Sensors fabricated using thermal spray technology have several unique advantages over traditional sensors that have to be mechanically attached to engineering components. The unique microstructure and nanometerscale features associated with thermal spray coatings, including pores and cracks, voids, the presence of many splat-splat interfaces and micro cracks all result in unique thermal, mechanical, and electrical properties that result in excellent performance at very high temperatures (1000+ oC) and in harsh environments. These sensors can be fabricated directly onto engineering components for outstanding reliability. A key application for these sensors is their use in land-based turbines and high-temperature, high-pressure boilers for more efficient power generation, condition-based (vs. failure-based) maintenance, and optimal performance. The work is funded by federal and industrial sources.
