利用电子显微分析技术研究了金属 /陶瓷梯度热障涂层中粘结金属的微观组织特征 .试验表明 ,粘结金属呈层状或颗粒状 ,有明显的塑性变形 ,其变形方式主要是位错运动、形变孪晶和生长孪晶 ;粘结金属中元素分布不均匀
The microstructure of the bond metal in the metal / ceramic gradient thermal barrier coatings was studied by means of electron microscopy (TEM) .Experimental results showed that the bond metal was layered or granular with obvious plastic deformation and the deformation mode was mainly Wrong movement, deformation twins and growth twins; uneven distribution of the elements in the bond metal
