Another mullite coating was then deposited on the ZM inner coating by the second step of APS with the parameters listed in Table 1.Fig.3a displays the SEM images of the coated mullite.The surface of the coating exhibits a homogeneity structure without crack,as well as a low porosity It is well known that good melting degree,narrow size distribution and high kinetic energy of feedstock particles can all reduce porosity.As shown in Fig.3b,the multilayer coating exhibits typical two-layer structure:the outer mullite layer(60~80μm)and inner Zr B2-Mo Si2 layer(100~120μm).
