Abstract
Abradable coatings have been proven to significantly improve the performance of gas turbine engines by serving as a protective barrier between rotating blades and stationary casing. While a significant amount of research has been performed on the development of novel abradable coatings over the last few decades, there is limited work focusing on the wear mechanisms within the abradable-blade tip interaction. Therefore, the main purpose of this study is to critically review alternative methodologies to assess abradable coatings and their interactions with the blade tips, simulating an application-relevant environment. Various abradable test rigs are discussed with a wide range of inputs and outputs, such as blade tip velocity, incursion rates, incursion depths, reaction forces, rubbing temperatures, and smoothness of cutting. Throughout this study, by a meticulous selection of mechanical and electronic components, low-cost promising equipment was designed and developed. The cost-effective abradable test rig can provide valuable insights into the wear behaviour of abradable coatings and can aid in the development of more effective wear-resistant coatings by a pre-screening methodology.
