對(duì)于渦輪葉片原有的功能（隔熱、耐蝕、耐磨）防護(hù)涂層厚度很小，涂層與葉片厚度比平均在1%左右，通常只有當(dāng)涂層厚度為葉片厚度的2～5%時(shí)才可獲得顯著的阻尼效應(yīng)。因此，涂層自身的阻尼減振能力很低，不能滿足其阻尼減振要求。金屬涂層界面的引入可能會(huì)提高其阻尼能力。由此看來，金屬涂層結(jié)構(gòu)的界面是影響其阻尼性能的一個(gè)關(guān)鍵制約因素。 The thickness of protective coatings (insulation, corrosion, wear) is very small in the turbine blade, and coating thickness is about 1% of the thickness of the blade. It will usually gain a significant damping effect, only when coating thickness is about 2～5% of the thickness of the blade. Therefore, the coating itself can not meet the requirements of the damping vibration because of a 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.

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. |
