The thickness of protective coatings (insulation, corrosion, wear) is very small in the turbine blade, and is about 1% of the blade thickness. It usually gains a significant damping effect only when coating thickness is about 2¡«5% of the blade thickness. Therefore, the coating itself is not able to meet the requirements of the damping vibration because of its very low damping vibration capabilities. The introduction of interface of metal coating may increase its damping capacity. In view of this, the interface of the metal coating structure is one of the key constraints which affect its damping performance. |

Ref: The thickness of the protective coatings (for heat insulation, corrosion and wear resistances) on the turbine blade is as small as 1% of that of the blade. Since the damping effect usually becomes significant only when the coating thickness is about 2¡«5% of the that of the blade, the coating itself, which provides a very low damping vibration capabilities, cannot meet the requirements for the damping vibration. However, the introduction of metal coating interface may increase the damping capacity. In point of this view, the interface of the metal coating structure is one of the key constraining elements influencing (affacting) the damping properties. |
