RESIDUAL STRESS AND STRESS RELAXATION IN CVD SiC-C GRADIENT COATINGS ON ZrB_2 CERAMICS
CVD·SiC-C 梯度涂层中的残余应力及应力缓和

SiC-C gradient coatings were prepared by using thermal Chemical VapourDeposition (CVD) method.The residual stress,microstructure and composition of the gra-dient coatings were inerstigted.It can be indicated that thermal stress and interface stressbetween
