Study of solid particle impact effects and coating thickness on the erosion damage

摘要: The development of high performance coatings for the protection against erosion requires understanding their complex failure mechanisms occurring during solid particle impact. In present work, a numerical analysis is carried out to study effect diameter, velocity, and coating thickness on damage gas turbine blade caused by erosion. For this purpose, assessment done using scanning electron microscopic testing. Furthermore, simulation impact plate performed finite element method commercially available software ABAQUS. particular, following values diameter (dP), velocity (VP), (tC) have been analyzed: 20 µm ≤dP ≤80 µm, 80 m/s ≤VP ≤120 m/s 5 µm ≤tC ≤12 µm. results demonstrate that in 1.6 times more effective than di...
