论文简介
Abstract The elastic modulus of plasma-sprayed top coating plays an important role in
thermal cyclic lifetime of thermally sprayed thermal barrier coatings (TBCs), since the
thermal stress is determined by the substrate/coating thermal mismatch and the elastic
modulus of top coating. Consequently, much attention had been paid to understanding the
relationship between elastic modulus and lamellar structure of top coating. However,
neglecting the intra-splat cracks connected with inter-splat pores often leads to poor ...
