Real-time wear and corrosion measurement provides crucial information in determining an optimal schedule for corrective maintenance and is a powerful tool to maximize equipment availability and reliability. This paper presents integrated ultrasonic transducers (IUTs) that—when incorporated into structures to accurately measure the remaining thickness—can determine wear or corrosion losses. Transducers have a small footprint, perform comparable to other commercial ultrasonic transducers, and can withstand temperatures up to 400ºC. Results show that thickness changes of a few micrometres can be detected. Applications of this technology to mining equipment and its potential benefits are discussed.
