摘要
Abstract
A coating constituted of MoSi2 and melted glass with the high emittance was prepared.The effects of the coating on the microstructure and performances of the rigid tiles were investigated.The results indicated that thewaterproof coating was dense with an emittance of about 0.85.After coating process,the flexural strength and shore hardness of the rigid tiles increased.The tensile strength in transverse orientation was about 50％ of that without coating.The back side temperature of rigid tiles with coating was higer than that without coating,when rigid tile was exposed to the radiation heat.However,the back side temperature of rigid tiles with coating was lower than that without coating,when rigid tile was exposed to the simulative heat of re-entry.The rigid tiles with coating created a little hole after the chip attack.关键词
