摘要

摘要: 在封严涂层弹性模量试验的基础上，建立封严涂层摩擦有限元模型，对民航发动机铝硅聚苯酯封严涂层的摩擦过程进行有限元分析。分析了摩擦系数、涂层厚度和粘结层厚度等参数对涂层/粘结层/基体系统应力分布的影响。分析结果表明：在切向载荷的作用下，随着摩擦系数的增大，涂层表面、涂层与粘结层的界面以及粘结层和基体界面处的应力峰值均增大；随着涂层厚度的增大，涂层表面及两界面处的应力峰值均减小，但当涂层厚度达到一定程度后，继续增加涂层厚度对降低应力峰值的效果不明显；粘结层厚度在一定范围内的变化对涂层表面和涂层与粘结层界面处的应力变化影响不大，但随着粘结层厚度的减小，粘结层与基体界面处的应力峰值均增大。

Abstract: On the basis of the seal coating elastic modulus experiemnts, the model for seal coating friction via finite element method was established, and the analysis on the stress distribution of AL/BN abradable sealing coating used in aeroengine was carried out. The influence of the friction coefficient, coating thickness and bonding layer thickness on the coating/bonding layer/substrate system was analyzed. The results show that under the tangential load, the peak stress on the coating surface, the interface of coating and bonding layer and the interface of bonding layer and substrate increase with the increasing of friction coefficient. The Peak stress on the coating surface and two interfaces decrease with the increasing of coating thickness. But when the thickness of coating reaches a certain degree, to increase the thickness of coating can't effectively decrease the peak stress. The thickness of bonding layer has small effect on the variation of stress on the coating surface and the interface of coating and bonding layer. But with the decreasing of bonding layer thickness, the stress peak on the interface of bonding layer and substrate increase.
