| Abstract: | This paper primarily discusses the feature of residual thermal stress on the interface between ceramic particle and matrix of laser cladding layer.The residual stress results from the difference of thermal expand coefficient of two phases.Under certain hypothesizes,the results of finite element calculation and stress strain analysis demonstrate the influences of volume fraction ( f v) and the shape of ceramic upon the stress distribution on the interface between ceramic and matrix. |
